Run the math on a $500,000 home at today’s 6.53% mortgage rate and your monthly PITI lands around $3,450 — before maintenance, HOA, or the opportunity cost of a $100,000 down payment sitting outside a portfolio that has historically returned 7% annually. That opportunity cost alone adds roughly $7,000 per year to the true cost of owning. Whether buying actually beats renting over time depends entirely on how long you stay — and most financial coverage gets this calculation wrong by ignoring transaction costs at exit.

The Cost Structure of Buying
At a $500,000 purchase price — slightly above the current national median, representative of mid-tier markets for $150k+ households — a 20% down payment ($100,000) leaves an $400,000 mortgage. At 6.53% on a 30-year fixed, per Freddie Mac’s PMMS reading of May 28, 2026, the principal-and-interest payment comes to approximately $2,540 per month. Add property taxes at the ATTOM national effective rate of 0.90% ($375/month), homeowner’s insurance (typically $150–$200/month), and the full PITI sits around $3,100–$3,115 monthly before any HOA.
Maintenance is the cost buyers most systematically underestimate. The standard modeling assumption — and the one used here — is 1% of home value annually, or $5,000/year on a $500,000 property. That figure is a floor, not a ceiling: ATTOM’s 2025 property tax data showed average bills rose 3% in a single year, and deferred maintenance on older stock runs higher. Over a decade at 3% annual home appreciation, a $500,000 home reaches roughly $672,000, and 1% maintenance on that terminal value is $6,720/year.
Then there are transaction costs. Buying costs 2%–5% of purchase price in closing costs (Redfin, March 2026 data). Selling costs roughly 5%–6% in agent commissions — a figure that has become more variable post-2024 NAR settlement but remains the market norm — plus additional closing fees. On a $500,000 purchase, budget $10,000–$25,000 to get in and $25,000–$30,000 to get out. Those exit costs are why short holding periods almost always favor renting. For deeper analysis of how rent vs. buying economics shift for high earners moving in 3 years, the break-even math is even more decisive.
The Opportunity Cost Nobody Accounts For
Opportunity cost is the return foregone by committing capital to one use instead of its next best alternative. Here, that means the $100,000 down payment sitting in home equity rather than in an invested portfolio. Assuming 7% annual return on invested down payment, consistent with the S&P 500 long-term historical average (Federal Reserve long-term asset return data), that $100,000 grows to roughly $197,000 over ten years. The cumulative opportunity cost — the wealth not accumulated — exceeds $97,000 over that decade. The analysis of opportunity cost of a down payment in dollar terms shows this is frequently the largest single variable in the buy-rent comparison, yet it appears in almost no mortgage calculator marketed to buyers.
At $750,000 — a more relevant price point for $150k+ households in coastal or high-demand metros — the 20% down payment hits $150,000, and the ten-year opportunity cost at 7% compounded exceeds $145,000. This is not a rounding error in the analysis. It is often the difference between owning favoring and renting favoring, depending on how aggressively the home appreciates.
The Cost Structure of Renting
Renting’s cost stream is simpler but has its own escalator built in. BLS data shows CPI rent of primary residence rising 2.7% year-over-year as of February 2026 — down from 3.0% in November 2025, a deceleration consistent with the new-supply wave that hit many metros in 2024–2025. For modeling purposes, the base-case assumption of 3% annual rent growth is slightly above the current BLS pace, making it mildly conservative for renters. The bear case for renting uses 4% annual escalation.
At $500,000 equivalent home value, a reasonable market rent for a comparable unit runs approximately $2,000–$2,500/month in most secondary markets, rising to $3,500–$5,000+ in expensive coastal metros. For this analysis, the base-case equivalent rent on a $500,000 property is set at $2,200/month — a ratio of roughly 0.44%, within the historical norm of 0.4%–0.7% price-to-rent ratios nationally. Renter’s insurance adds roughly $15–$25/month. Total renting cost in Year 1: approximately $2,215–$2,225/month.
The renter also retains the down payment, invested at the stated 7% assumption. That retained capital is the primary mechanism by which renting can outperform buying over shorter horizons — even when rents rise faster than inflation. Understanding how current interest rate levels restructure the buy vs. rent decision helps clarify why this dynamic has intensified since 2022.
The Tax Benefit of Homeownership — Recalibrated
The 2026 tax landscape changed materially. The One Big Beautiful Bill Act raised the state and local tax deduction cap — the SALT cap, which limits the combined deduction for state income taxes and property taxes on federal returns — from $10,000 to $40,000 for 2025 and $40,400 for 2026 (IRS Revenue Procedure 2025-32). For the $150k+ household in a high-tax state, this expansion is significant. A household paying $18,000 in state income taxes and $8,000 in property taxes previously could deduct only $10,000; now they can deduct the full $26,000.
The catch for this audience: the expanded SALT cap phases down for MAGI over $505,000 in 2026, reducing by 30 cents for every dollar above that threshold, reverting to the $10,000 floor when MAGI reaches approximately $610,000. Households in the $500k–$610k MAGI range face a sliding benefit. Most $150k+ households who earn below $500k MAGI receive the full $40,400 cap, which meaningfully changes the itemization calculus. The 2026 standard deduction for married filing jointly is $32,200 (IRS). A household with $15,000 in mortgage interest, $8,000 in property taxes, and $18,000 in state income taxes — $41,000 in SALT-plus-mortgage-interest deductions — clears the standard deduction threshold and saves real money itemizing. The full dollar value of this benefit is explored in detail in our analysis of the tax benefit of homeownership in real dollar terms.
But the mortgage interest deduction is not what it used to be. At 6.53%, a $400,000 mortgage generates roughly $26,000 in interest in Year 1 — declining each year as principal is paid down. By Year 10, annual interest drops to approximately $20,000. This is still meaningful, but only to the taxpayer who itemizes, and only to the extent deductions exceed $32,200. A household with low state income taxes (think Texas, Florida, or Nevada) and modest property taxes may find the standard deduction superior regardless of the SALT expansion.
Finluxy Buy-Rent Break-Even Horizon
The Finluxy Buy-Rent Break-Even Horizon measures the number of years until cumulative cost of buying — including all transaction costs at both entry and exit — equals the cumulative cost of renting the equivalent property. Below are three scenarios calculated for a $500,000 home purchase with 20% down ($100,000), at the current 6.53% 30-year fixed rate. Equivalent monthly rent: $2,200. Maintenance: 1% of home value annually. Property tax: 0.90% of value. HOA: $0 assumed (single-family). Buyer closing costs: 3% of purchase price ($15,000). Seller transaction costs at exit: 5.5% of sale price. Investment return on down payment: stated per scenario.
| Scenario | Home Appreciation | Rent Growth | Investment Return (Down Payment) | Break-Even Horizon | Interpretation |
|---|---|---|---|---|---|
| Base Case | 3% / year | 3% / year | 7% / year | ~9–10 years | Market-dependent; location and tax profile are decisive |
| Bull Case (Owning Favored) | 5% / year | 4% / year | 5% / year | ~6–7 years | Strong buy case; buyers who stay 7+ years likely ahead |
| Bear Case (Renting Favored) | 1% / year | 2% / year | 9% / year | ~15–17 years | Renting likely better; equity growth too slow to overcome opportunity cost |
Finluxy proprietary model. Inputs derived from: Freddie Mac PMMS (rate, May 28, 2026); ATTOM 2025 Property Tax Analysis (property tax rate); Redfin (closing costs, March 2026); Federal Reserve / S&P 500 long-term historical return data (investment return assumption); BLS CPI Rent of Primary Residence (rent growth calibration). Appreciation scenarios bracket NAR’s 2026 full-year forecast (+4%) against current YoY pace (+0.9%). Bear-case investment return reflects equity bull markets of recent years. These are illustrative scenarios, not predictions.
What the Data Actually Shows That Most Coverage Misses
Most buy-vs-rent articles model a clean comparison at purchase and ignore what happens at exit. The standard NAR-adjacent framing — “buyers build equity, renters don’t” — is not wrong, but it omits the 5%–6% seller cost that vaporizes equity the moment you sell. On a $500,000 home appreciating at 3% annually, the gross sale price after 7 years is approximately $615,000. Seller transaction costs at 5.5% consume about $33,800. Net equity recovered: roughly $281,000 against a paid-in down payment of $100,000 plus seven years of principal paydown and maintenance contributions. That’s a meaningful gain — but the renter who invested $100,000 at 7% compounded for seven years has $161,000, plus avoided $25,000+ in transaction costs and $35,000+ in maintenance. The gap between the two outcomes is much narrower than either party’s advocate typically presents.
The overlooked insight in the current data: the SALT cap expansion from $10,000 to $40,400 meaningfully shifts the break-even horizon for $150k+ households in high-tax states — potentially shortening it by 1–2 years depending on marginal rate. A household in the 32% bracket (income $201,775–$403,550 for single filers, $403,550–$512,450 for MFJ in 2026) itemizing $40,000 in SALT-plus-mortgage-interest saves approximately $12,800 annually in federal taxes versus taking the standard deduction. Over ten years, that’s $128,000 in cumulative tax savings — enough to close a substantial portion of the opportunity cost gap. This makes the OBBBA arguably the most significant development for homeownership economics since the 2017 TCJA, yet it is barely mentioned in mainstream buy-vs-rent coverage.
Markets with structurally high rent growth — primarily supply-constrained metros — compress break-even horizons faster than appreciation does. When rents grow at 4%+ annually (above the current national BLS pace but not unusual in tight markets), the renter’s monthly cost escalates faster, making the fixed mortgage payment increasingly attractive by comparison. This dynamic is especially pronounced in markets like New York, where the buy vs. rent break-even math in NYC runs longer due to price levels but is partially offset by high rent escalation. Similarly, the San Francisco buy vs. rent analysis illustrates how extreme price-to-rent ratios can push break-even past 14 years even with strong appreciation.
Price Point Sensitivity: $400k, $700k, $1M+
The break-even horizon is not linear across price points. At $400,000 — below the current median but relevant in secondary markets — a 20% down payment is $80,000, the opportunity cost is lower, and equivalent rents in those same markets are often $1,600–$1,900/month. The base-case break-even compresses toward 7–8 years. Owning is more defensible at this price tier, particularly for buyers with stable 5–7 year horizons.
At $700,000, the 20% down payment reaches $140,000, opportunity cost at 7% compounded over ten years exceeds $135,000, and the monthly PITI at 6.53% approaches $4,300–$4,400 before maintenance. Equivalent rents in markets where $700,000 homes trade are typically $2,800–$3,600/month. The base-case break-even stretches to 10–12 years. For a granular walk-through of this specific tier, the renting vs. buying analysis at the $1M price point shows the math deteriorates further as price-to-rent ratios widen.
Above $1 million, the economics of renting luxury property deserve separate consideration. Price-to-rent ratios in high-end markets often reach 25–35x annual rent, implying gross rental yields of 2.9%–4.0% — barely above mortgage rates, with no maintenance included. The case for renting luxury when it makes more financial sense is strongest at this tier. At $1.5 million with 20% down ($300,000), the opportunity cost alone on the invested down payment at 7% over ten years exceeds $290,000.
How Current Rates Reshape Everything
The 30-year fixed averaged 6.53% as of May 28, 2026 (Freddie Mac PMMS), down from 6.89% a year earlier but still far above the 2.65%–3.5% range that defined 2020–2022. This rate environment matters not just for payment size but for the amortization structure: at 6.53%, only about 22% of the first year’s principal-and-interest payment goes toward principal. The equity buildup in early years is painfully slow. A buyer on a $400,000 mortgage has paid down only about $24,000 in principal after three years — roughly 6% of the loan — yet has absorbed three years of maintenance, property taxes, and the full opportunity cost of their $100,000 down payment sitting outside the market.
For $150k+ households, the rate sensitivity is material. A 1 percentage point drop in the 30-year fixed — to 5.53%, plausible if the Fed eases aggressively — cuts the monthly P&I on a $400,000 mortgage by roughly $275/month, or $3,300/year. That kind of rate shift shortens the base-case break-even by approximately 1.5–2 years. This is the calculation behind the widespread “marry the house, date the rate” advice — which is directionally correct but ignores refinancing costs (typically 2%–3% of loan balance) and the uncertainty of rate trajectories. The interest rate impact on the buy vs. rent decision shows how sensitive break-even horizons are to rate changes at different price points.
The $150k+ Household Context
A household earning $150,000–$300,000 is generally in the 22%–32% federal marginal bracket in 2026 (IRS). At these income levels, the SALT cap expansion to $40,400 restores a real tax benefit to homeownership in high-tax states — one that had been largely eliminated by the 2017 TCJA. For a 32%-bracket household in California or New Jersey paying $15,000 in property taxes and $22,000 in state income taxes, the ability to deduct $37,000 (capped at $40,400) generates meaningful federal tax savings versus the $32,200 standard deduction. This is not a marginal benefit: it can shift the base-case break-even by 12–18 months.
At household incomes above $400,000 — still within the $150k+ framing but at the upper end — the picture shifts. Mortgage interest deductibility phases out gradually through higher amortization, and households approaching $500,000 MAGI need to model the SALT phasedown. A couple with $520,000 MAGI in 2026 sees their $40,400 SALT cap reduced by 30% of the $15,000 excess over $505,000, leaving a $35,900 cap — still far more valuable than the prior $10,000 ceiling, but the benefit erodes toward $500k MAGI and vanishes near $610,000 MAGI.
For this income bracket, the buy-vs-rent decision is ultimately a portfolio allocation question. Buying a home concentrates capital in an illiquid, leveraged, single-asset position. In the base scenario, that asset delivers roughly 3% appreciation annually — below the long-run S&P 500 average and comparable to a bond portfolio but with leverage amplifying both upside and downside. Renting maintains optionality and liquidity, which has real value for high earners whose income might shift, whose careers might move them, or who want dry powder for other investments. The Austin post-surge buy vs. rent analysis illustrates what happens to break-even horizons when appreciation assumptions prove too optimistic — a cautionary case study in single-market concentration risk.
Markets matter as much as the macro inputs. The same $150k+ household will face dramatically different outcomes in Chicago — where property tax rates run well above the national 0.90% average (Illinois effective rate: 1.84%, ATTOM 2025) — versus Phoenix, where the Sun Belt supply wave has compressed rents and moderated appreciation. Chicago’s buy vs. rent break-even timeline is extended by property tax burden alone. Miami’s analysis shifts meaningfully as insurance costs — not modeled in the national framework here — add $3,000–$8,000 annually in coastal Florida markets; the Miami buy vs. rent impact of 2026 rate levels addresses this directly.
Methodology
The Finluxy Buy-Rent Break-Even Horizon is calculated by modeling the cumulative net cost of buying — including PITI (principal, interest, taxes, insurance), maintenance at 1% of home value annually, HOA (zero for this analysis), entry closing costs (3% of purchase price), and seller transaction costs at exit (5.5% of sale price) — against the cumulative net cost of renting the equivalent property, including rent growing at the stated annual rate, renter’s insurance ($20/month), and the opportunity cost of the down payment invested at the stated annual return.
Tax benefits are modeled for the itemizing scenario: mortgage interest and property taxes are deducted at the marginal federal rate, subject to 2026 SALT cap constraints. The analysis does not assume state income tax deductibility in the mortgage interest figure because state treatment varies. The break-even year is identified when the cumulative ownership advantage — equity built minus opportunity cost lost minus transaction costs — turns positive relative to the renter’s accumulated invested capital. Three scenario variants are presented to capture uncertainty in appreciation, rent growth, and investment returns.

Federal Reserve long-term asset return data informs the 7% S&P 500 return assumption. The NYT Rent vs. Buy calculator methodology is the industry standard for this type of analysis and was used as a structural reference for the cost stream framework.

Frequently Asked Questions
What does the SALT cap change mean for homeowners in 2026?
The One Big Beautiful Bill Act raised the state and local tax deduction cap to $40,000 for tax year 2025 and $40,400 for 2026 (IRS Rev. Proc. 2025-32), a dramatic increase from the previous $10,000 TCJA ceiling. For $150k+ households in high-tax states who itemize, this restores a meaningful portion of the homeownership tax benefit that was eliminated in 2017. The expanded cap begins phasing down at MAGI over $505,000 in 2026, reaching the $10,000 floor near $610,000 MAGI. The cap reverts to $10,000 in 2030 unless Congress acts again.
How long do I need to stay to justify buying at today’s rates?
Under base-case assumptions (3% appreciation, 3% rent growth, 7% investment return on down payment), the Finluxy Buy-Rent Break-Even Horizon for a $500,000 home at 6.53% runs approximately 9–10 years. In the bull scenario (5% appreciation, 4% rent growth, 5% investment return), it compresses to 6–7 years. Households planning to move within five years should almost certainly rent unless they are in a market with historically strong rent escalation and limited alternative investment returns. The detailed math for rent vs. buy for high earners moving in 3 years shows how transaction costs dominate over short horizons.
What is the opportunity cost of a down payment, and why does it matter?
Opportunity cost is the return foregone by committing capital to one use instead of its next best alternative. A $100,000 down payment invested at 7% annually — consistent with the S&P 500 long-term historical average — grows to roughly $197,000 over ten years. That $97,000 in foregone growth is the opportunity cost of homeownership, and it must be offset by appreciation, equity buildup, and tax savings for buying to win financially. At $150,000 down (20% on a $750,000 home), the ten-year opportunity cost exceeds $145,000.
Does the 1% maintenance rule hold at higher price points?
The 1% annual maintenance rule is a floor, not a ceiling, and it becomes less accurate at higher price points where finishes are more expensive but square footage doesn’t necessarily scale proportionally with cost. A $1.5 million historic brownstone in a coastal city will routinely cost more than $15,000/year to maintain. Some financial planners use 1%–2% of home value as the planning range, with older homes and larger properties trending toward the high end. For $150k+ households purchasing above $800,000, budgeting 1.25%–1.5% annually produces a more realistic ownership cost model.
