The Rent vs. Buy Decision

A data-driven framework for the biggest housing decision

Should you rent or buy? The answer isn't always 'buy' — it depends on your timeline, market, finances, and lifestyle. Here's how to make the right choice.

1The Break-Even Calculation

The key question: How long until buying costs less than renting?
Factors that favor buying:
  • You plan to stay 5+ years
  • Home prices are appreciating
  • Rent is rising faster than mortgage costs
  • You have strong credit and down payment

Factors that favor renting:
  • You may relocate within 3 years
  • The price-to-rent ratio is high (above 20)
  • You'd drain savings for the down payment
  • You value flexibility over equity

2True Cost of Ownership

Buying costs more than just the mortgage:
Monthly costs:
  • Mortgage (principal + interest)
  • Property taxes (~1–2.5% of value/year)
  • Homeowners insurance ($100–300/month)
  • PMI if under 20% down ($100–400/month)
  • HOA fees (if applicable)
  • Maintenance (~1% of value/year)

One-time costs:
  • Down payment (3–20% of price)
  • Closing costs (2–5% of loan)
  • Moving expenses
  • Initial repairs/improvements

3The Wealth-Building Argument

Buying builds equity in three ways:
  1. Forced savings: Each payment reduces your loan balance
  2. Appreciation: Home values historically rise 3–5%/year
  3. Leverage: A 20% down payment controls 100% of the asset

But consider the flip side:
  • Your down payment could be invested in the stock market
  • Home maintenance and repairs eat into returns
  • Homes aren't liquid — selling takes time and costs 6–10%
  • Past appreciation doesn't guarantee future returns

Pro Tips

  • Price-to-Rent ratio: Home price ÷ Annual rent. Below 15 = buying favored, above 20 = renting favored
  • Don't buy just because 'everyone says to' — run the numbers
  • Factor in opportunity cost of your down payment
  • Consider hybrid: rent now, invest the savings, buy later
