The Rent You Weren't Wasting
"Renting is throwing money away" assumes owning isn't. But a big share of every mortgage payment (interest, property tax, upkeep, the return your down payment isn't earning elsewhere) is money you never get back either. Add those up and they come to about 5% of the home's value, every year. That number is the whole answer, and you can move it yourself.
The rent-vs-buy fight usually pits your rent against your whole mortgage payment. And rent loses, because part of a mortgage payment buys you equity. That comparison is rigged. The honest one is unrecoverable cost vs unrecoverable cost: the rent you'll never see again against the part of owning you'll never see again. Portfolio manager Ben Felix (PWL Capital) packed the owning side into one rule of thumb.
Layer 1: the 5% line
Owning's yearly unrecoverable cost ≈ property tax + maintenance + cost of capital. Felix's defaults: about 1% + 1% + 3% = 5% of the home's value. Divide the price by that 5%, then by 12, and you get the monthly rent that costs the same as owning. Below it, renting is the cheaper way to put a roof over your head.

of home value / yr
Annual cost of owning
$25,000
gone, never recovered
Break-even monthly rent
$2,083
price × rate ÷ 12
Set your rent to compare.
That's the crisp, extractable answer: for a $500,000 home at Felix's 5% defaults, owning burns $25,000/yr you never get back, so any rent under ~$2,083/mo is the cheaper roof. Renting isn't "throwing money away": it's often throwing less away.
Layer 2: where the fear is right, and the frame flips
The 5% line is honest about costs, but it isn't the whole story about wealth. And here the "throwing money away" instinct has a real kernel. An owner is leveraged: a 20% down payment captures the appreciation of the entire home. And one-time transaction costs (~5% to buy, ~5% to sell) are brutal over a short stay but amortize toward nothing over a long one. So the true test isn't just cost parity; it's a fair net-worth race. Give the renter the down payment to invest, and every month let whoever spends less on housing invest the difference. Then run the clock.

The renter's rent is the break-even rent from Layer 1 ($2,083/mo), so both sides carry the same housing budget: the race is decided purely by leverage, appreciation, returns and time, not by an unfair rent.
Try it: at the defaults (6.5% return beating 3.5% appreciation, a 9-year stay) the renter wins: the down payment compounding in the market outruns leveraged equity net of transaction costs. Now drag appreciation up toward the return: leverage takes over (the owner is earning that return on the whole home from a fraction down) and the owner pulls ahead. Two honest caveats the fifty thin explainers skip: while housing trails the market by those 3 points, the renter wins at every horizon (the "break-even year" reads >30). A long stay only rescues owning once appreciation is competitive, where round-trip costs make a short stay the real loser. And this model freezes your rent forever; a rising rent is precisely the inflation hedge a fixed mortgage payment buys, so long horizons favor owning by more than shown here.
Why the early years feel like "throwing money away"
On a fresh 30-year mortgage almost none of your first payment is equity: it's nearly all interest, which is every bit as unrecoverable as rent. Here's the split of your first payment at the current price, rate and down payment:
Only the principal slice builds equity; the interest slice is gone like rent. Early on, an owner really is "throwing away" most of the payment, just to a bank instead of a landlord. That's why a short stay favors renting.
The check: every number recomputed live
The 5% line is arithmetic; the race is standard mortgage amortization plus compound growth. Both are computed in your browser from the equations below; nothing is a stored answer. Press the button to re-derive the headline numbers two independent ways.
Free choices & uncertainties (dial them and the answer moves):
- The 3% "cost of capital" is the load-bearing assumption. It's Felix's blended figure from a low-rate era and bakes in that home appreciation trails a diversified portfolio: historically defensible (long-run US real house prices ≈ 0–1%/yr, well under equities) but a contested magnitude that's higher when mortgage rates are high. The race exposes it directly with separate rate / return / appreciation sliders.
- Property tax and maintenance ≈ 1% each are US-average heuristics; both vary widely by state, home age and condition (maintenance can top 2%). They're defaults, not your numbers.
- Transaction costs are fixed at 5% to buy + 5% to sell (~10% round-trip), essential, not optional. They're why a short horizon favors renting and a long one favors owning.
- The race credits the owner with appreciation on the full home (the leverage effect) and charges selling costs; it credits the renter with the down payment and every monthly surplus, compounded. It ignores mortgage-interest and property-tax deductions, primary-residence capital-gains exclusions, rent inflation and insurance: simplifications that can favor either side.

When each side wins
| Factor | Renting wins when… | Buying wins when… |
|---|---|---|
| Horizon | Short stay (a few years): transaction costs dominate | Long stay: one-time ~10% round-trip amortizes to near zero |
| Rent level | Rent below price × 5% ÷ 12 | A year's rent exceeds 5% of the price (hot rental markets) |
| Leverage | You'd invest the down payment instead | A small down payment captures appreciation on the whole home |
| Appreciation vs return | Diversified portfolio out-returns local housing | Local housing appreciates near or above the market |
| Taxes | Low bracket; little to shelter | High bracket: primary-residence gains are largely tax-free |
| Behavior | You reliably invest the difference | The mortgage is forced savings; the fixed payment hedges inflation |
The five cases Felix says buying wins
- Long horizon. Transaction costs (~5% buy + ~5% sell) are a fixed toll; spread over decades they shrink to a rounding error.
- High-rent markets. Where a year's rent already exceeds 5% of the purchase price, the unrecoverable-cost comparison flips toward owning.
- High-bracket taxable investors. Gains on a primary residence get preferential, often tax-free treatment that a taxable portfolio doesn't.
- Leverage. A mortgage lets a small down payment capture appreciation on the full home value: the one place the "equity" instinct is genuinely right.
- Forced savings + inflation hedge. A mortgage makes you save whether you're disciplined or not, and a fixed nominal payment quietly shrinks in real terms as prices rise.
What's exactly true here, and what's simplified
Exactly true. The 5% line is plain arithmetic and Felix's own headline: tax% + maintenance% + cost-of-capital% of home value per year, with break-even rent = price × that% ÷ 12. The mortgage payment and remaining-balance formulas are the standard closed forms, and the page cross-checks them against a month-by-month amortization that lands the balance on zero at term. The leverage and horizon effects in the race are real mechanics, not rhetoric.
Simplified. The race assumes a fixed-rate mortgage held to your exit, constant appreciation and constant returns (both are volatile in reality), a rent equal to the Layer-1 break-even, and no taxes, insurance, HOA fees or rent increases. It ignores the mortgage-interest and property-tax deductions, the primary-residence capital-gains exclusion, and PMI on small down payments: each of which shifts the line but none of which reverses the structure.
Contested magnitude. The single most debated input is whether housing appreciation trails a diversified portfolio. Long-run US real home-price growth is roughly 0–1%/yr (Case–Shiller / Robert Shiller's series), historically well below equities. But it's market- and era-dependent, and a decade of double-digit local appreciation flips the verdict. That's why appreciation is a slider, not a hidden constant.
