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:

- Rent is rising faster than mortgage costs
- You have strong credit and down payment
Factors that favor renting:

- 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:
One-time costs:
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:
But consider the flip side:
- Forced savings: Each payment reduces your loan balance
- Appreciation: Home values historically rise 3–5%/year
- 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
