Rent-vs-buy is both a math question and a life question. The math: over a 7-10 year horizon, buying usually wins if you put 10%+ down at a reasonable rate, stay long enough to amortize closing costs, and the rental alternative is at least 80% as expensive as the PITI. The life question: are you actually ready to own — financially, logistically, and emotionally? Most "I bought too early" regrets come from skipping the second question.
Worked example: $425,000 home, 20% down, 7% rate vs renting a comparable place for $2,600/mo. After 10 years, owner has ~$275,000 in home equity (principal paydown + modest appreciation). Renter invested the $85,000 down payment plus monthly-payment-delta at 7% return — ends with ~$245,000 in portfolio. Owner wins by $30,000 IF they stay 10 years. Sell in year 3 and the renter wins by $50,000 because of closing costs on both ends.
The numbers that matter
- Expected tenure. Under 3 years, always rent. 3-5 years, usually rent. 7+ years, usually buy.
- Rent/buy ratio. Annual rent for a comparable place divided by purchase price. Under 3% (monthly rent of 0.25% or less of purchase) strongly favors renting. Over 6% strongly favors buying. 3-6% is the gray zone.
- Maintenance. 1-2% of home value per year goes into maintenance, taxes on appreciation, and the boring cost of ownership. Most rent-vs-buy calculators skip this and bias toward buying.
- Opportunity cost of down payment. $80,000 in index funds at 7% doubles every 10 years. A rent-vs-buy comparison that ignores this is hiding the ball.
Readiness quiz — 10 life questions
- Will I stay in this metro 5+ years?
- Is my job stable, or am I in a high-volatility field (startup, sales, contract)?
- Do I have 3-6 months of emergency fund after down payment and closing?
- Is my down payment fully mine, or am I stretching with borrowed money?
- Can I handle a $5,000 surprise repair (new HVAC, roof leak, sewer line) without panicking?
- Am I comfortable spending weekends on home projects, or is that a nightmare to me?
- Is my relationship situation stable (not mid-engagement, mid-divorce)?
- Have I rented long enough to know what I actually like in a place?
- Am I buying a starter home I can live in for 7 years, not a stretch home I'll outgrow in 3?
- Would losing 15% of home value on paper cause me to panic-sell?
8+ yesses: ready to buy. 5-7 yesses: fine to rent another year and stack the win. Under 5: keep renting.
Markets where renting beats buying in 2026
San Francisco, Manhattan, Seattle, Austin and a handful of other metros have rent/buy ratios under 3% — meaning a $1.5M condo rents for $4,500/mo. Owning that condo costs roughly $10,000/mo in PITI + maintenance. Unless you expect 5%+ annual appreciation continuing, the math heavily favors renting and investing the difference.
Markets where buying wins hard
Much of the Midwest and South — Cleveland, Pittsburgh, Kansas City, Memphis, Birmingham — has rent/buy ratios above 7%. A $250,000 home rents for $2,100/mo. Owning is $1,700 all-in. Buying is a no-brainer if you plan to stay.
