Buy vs Rent: Frequently Asked Questions

Deciding whether to buy a home or keep renting is one of the biggest financial choices you can make. Here are answers to the questions we hear most often.

Is it better to buy or rent a house?

It depends on your financial situation, how long you plan to stay, local market conditions, and your investment strategy. Buying builds equity and provides stability, while renting offers flexibility and frees up capital for other investments. In general, the longer you stay in one place, the more buying tends to favor you — but that's not always the case. Use our calculator to compare the numbers for your specific situation.

What is the 5% rule for buying vs renting?

The 5% rule is a quick way to estimate whether buying or renting is cheaper. Multiply the home's value by 5% and divide by 12 to get a monthly breakeven rent. If your actual rent is below that number, renting may be the better financial choice. The 5% accounts for roughly 1% property tax, 1% maintenance, and 3% cost of capital (the opportunity cost of your down payment and equity).

How much should I save before buying a home?

Most financial advisors recommend saving at least 20% of the home price for a down payment. This lets you avoid private mortgage insurance (PMI), which can add hundreds of dollars to your monthly payment. Beyond the down payment, budget 2–5% of the purchase price for closing costs, and keep an emergency fund of 3–6 months of living expenses. Our calculator defaults to a 20% down payment based on the median US home price.

Does renting or buying build more wealth over time?

Both can build wealth, but through different mechanisms. Homeowners build equity as they pay down their mortgage and if their property appreciates. Renters can build wealth by investing the difference between what they'd pay as a homeowner and their actual rent. The outcome depends on home price appreciation, investment returns, how long you stay, tax benefits, and your local housing market.

How do interest rates affect the buy vs rent decision?

Higher interest rates increase the cost of a mortgage, making buying more expensive relative to renting. A 1% increase in mortgage rates on a $400,000 loan can add over $200/month to your payment. When rates are high, renting and investing the difference may look more attractive. When rates are low, the math often favors buying sooner.

What costs of homeownership do people often overlook?

Beyond the mortgage payment, homeowners face property taxes (typically 1–2% of home value per year), homeowner's insurance, maintenance and repairs (budget 1–2% of home value annually), HOA fees, and closing costs when buying and selling. These "hidden" costs can add 30–50% on top of your mortgage payment. Our calculator factors in repairs and home value changes so you can see the full picture.

How long should I plan to stay to make buying worth it?

A common rule of thumb is at least 5–7 years, though this varies by market. In the first years of a mortgage, most of your payment goes toward interest rather than equity. Factor in closing costs (2–5% when buying, 6–10% when selling with agent fees), and you often need several years of appreciation to break even. Our calculator shows you the crossover point for your specific inputs.

What is the opportunity cost of a down payment?

Your down payment is money that could otherwise be invested. If you put $80,000 down on a home, that's $80,000 that isn't earning stock market returns. Over 10 years at a 7% average return, that could grow to roughly $157,000. The calculator accounts for this opportunity cost when comparing a renter's invested savings against a homeowner's equity.

How does the buy vs rent calculator work?

The calculator compares the total financial picture of buying a home against renting over a 30-year period. For buyers, it models mortgage payments, home appreciation, equity building, and repair costs. For renters, it models rent increases and investment growth on savings. It then compares cumulative housing costs, net worth, and liquid savings over time to help you see which strategy works better for your situation.
