Rent vs Buy 2026 — The Real Math Nobody Talks About

Everyone tells you buying is always better. The numbers don't agree — at least not until year 5 or 6 in most markets. Here's the complete picture: what ownership actually costs, when the break-even happens, and the one number that determines everything.

The Myth: "Renting Is Throwing Money Away"

This is the most repeated — and most misleading — piece of personal finance advice. Let's look at what buying a $400,000 home at 7% actually costs in year one:

Renting a similar $400,000 home costs roughly $2,400–$2,800/month in most US markets — about $29,000–$33,000/year. In year one, renting the same home is often $6,000–$10,000 cheaper than owning it, even before accounting for the opportunity cost of the down payment.

The Hidden Costs Nobody Mentions

When people calculate whether they can afford a house, they look at the mortgage payment. Here's what they forget:

• Property taxes: 1–2% of home value per year. On a $400K home: $4,000–$8,000/year. This rises as your home appreciates.
• Maintenance and repairs: Budget 1% of home value annually. That's $4,000/year on a $400K home — and older homes easily run 2–3%.
• Home insurance: $1,500–$3,500/year depending on location, size, and coverage.
• PMI: If you put less than 20% down, add $150–$300/month until you reach 20% equity.
• Closing costs: 2–5% of purchase price upfront. On a $400K home: $8,000–$20,000 just to close.
• Selling costs: When you eventually sell, expect 5–6% in agent commissions. On a $500K sale: $25,000–$30,000 gone.

When Does Buying Actually Win?

Buying wins — but it takes time. The break-even point is when total buying costs (including opportunity cost of down payment) equal total renting costs. Here's how it looks by market:

The key insight: if you move before the break-even, you almost certainly lost money buying vs renting. The average American moves every 7–8 years. In expensive markets, buying barely breaks even by then.

The 5% Rule — A Quick Gut Check

Economist Ben Felix popularized this shortcut: multiply the home price by 5%, divide by 12. If your rent is lower than this number, renting is likely better financially.

Example: $400,000 home × 5% = $20,000 ÷ 12 = $1,667/month.

If you can rent a similar home for under $1,667/month, the math favors renting. In most US cities, the rent on a $400K home is well above $1,667 — which is part of why buying wins long-term in most markets. But in cities like San Francisco or NYC where a $1.5M home rents for $4,000/month, the math is much closer to the break-even threshold.

The Investment Alternative

A $400,000 home requires roughly $90,000–$95,000 upfront (20% down + closing costs). What if you rented and invested that money instead?

$95,000 invested in a low-cost index fund averaging 8%/year grows to:

• After 5 years: $139,600
• After 10 years: $205,200
• After 20 years: $442,600

That's the opportunity cost of buying — the wealth you could have built by investing the down payment instead. Our calculator accounts for this in the comparison.

How Much Do You Need to Buy a Home in 2026?

Note: at 7% interest on a $400K home with 20% down, that $2,130/month is just the mortgage. Add $433 property tax, $150 insurance, $333 maintenance = $3,046/month true cost. Compare that to your rent carefully.
