"Rent is throwing money away" is the most expensive bumper sticker in personal finance. So is "always buy a house — it's an investment." Both ignore the actual math, which depends on your rate, your timeline, your local rent-to-price ratio, and what your down payment would have done in the market instead.
This guide walks the calculation honestly, including the variables most rent-vs-buy calculators leave blank.
What changed in 2026
- Rates above 6%. Mortgage interest is the largest line item for years. The break-even point moved further out.
- HYSAs and T-bills pay 4–5%. That's the new opportunity cost on your down payment.
- Insurance and property tax inflation. Both have outpaced general inflation in most metros for three straight years.
The variables that actually matter
- Purchase price and down payment.
- Mortgage rate and loan term.
- Property tax (1–3% of price/yr).
- Insurance ($1,500–$5,000/yr depending on metro).
- Maintenance (1–2% of home value/yr).
- HOA, if applicable.
- Comparable rent on the same property.
- Down payment opportunity cost (4–7% in safe assets, 7–10% in stocks).
- Time horizon (years you'll stay).
1. The 5% rule — best quick gut-check
Multiply the home's price by 5%. If your annual rent is less than that number, renting is mathematically equivalent or better. The 5% comes from rough averaging of property tax (1.1%), maintenance (1%), and the cost of capital after appreciation (~3%).
Example: $500,000 home → $25,000/year → about $2,083/month. If rent on a comparable place is $2,000, renting wins until those numbers shift.
2. The honest break-even — best for actual decisions
Run a 10-year side-by-side. Buy column: down payment + closing + every monthly cost. Rent column: monthly rent + invested down payment compounding at 5–7%. Compare net worth at year 10 under both.
The trade-off: it's tedious. The NYT rent-vs-buy calculator is the fastest honest tool. Plug in your actual rate, taxes, insurance, and a realistic 1.5% maintenance number.
3. The non-financial factors — best not ignored
Stability, customization, control, school zones, the freedom to drill a hole in the wall. These don't show up in spreadsheets but they're real. They tilt the answer toward buying for some people regardless of what the math says.
The reverse is also true: career mobility, optionality, and not wanting to be a part-time landscaper tilt others toward renting.

Common mistakes to avoid
Comparing rent to PITI alone. PITI omits maintenance, HOA, lawn, and major repairs. Add 1–1.5% of price/year to PITI to get the true monthly cost.
Ignoring opportunity cost. A $100k down payment in a 5% HYSA is $5,000/year you're not earning if it sits in walls. Calculators that omit this make buying look cheaper than it is.
Assuming high appreciation. National average is around 3–4% nominal. Pricing in 6–8% to make buying "win" is wishful thinking.
FAQ
What's the simplest rule?
If you'll move within 5 years, rent. If you'll stay 10+ years and rent is more than 5% of price annually, buy. In between, it depends.
Does buying still beat renting in HCOL cities?
Often no. NYC, SF, and parts of LA have rent-to-price ratios under 4%, which means renting plus investing the down payment usually wins.
What if rates drop?
Refinancing is real. But banking on a future rate cut is speculation. Buy at a payment that works today.
