Rent vs Buy Calculator

FAQ

Is it cheaper to rent or buy a house?

It depends on three key factors: how long you plan to stay, local rent-to-price ratios, and what return you could earn by investing your down payment. In expensive cities with high price-to-rent ratios (like San Francisco or NYC), renting often wins even long-term. In affordable markets, buying typically becomes cheaper after 5-7 years.

How long do you need to stay for buying to make sense?

The typical break-even point is 5-7 years, but this varies significantly. With 6%+ mortgage rates, it can take 8-10 years. In a strong real estate market with low rates, buying can win in 3-4 years. Use this calculator with your specific numbers to find your break-even point.

Is rent money really "thrown away"?

No, this is a common misconception. Rent pays for housing, flexibility, and zero maintenance responsibility. When you buy, a significant portion of your payment goes to interest (especially early in the loan), property taxes, insurance, and maintenance — none of which build equity. The key is comparing total costs, not just monthly payments.

What is opportunity cost and why does it matter?

Opportunity cost is what you give up by choosing one option over another. When buying, your down payment is locked in home equity instead of invested elsewhere. If your down payment could earn 7% in index funds but your home only appreciates 3%, you're losing 4% annually on that money. This hidden cost makes renting more competitive than most people realize.

Should I buy if mortgage rates are high (6%+)?

High mortgage rates significantly favor renting. At 6.5%, about 65% of your early mortgage payments go to interest, not equity. Consider renting and investing until rates drop, then refinancing. However, if you plan to stay 15+ years and expect rates to drop for a refinance, buying may still work.

How does home appreciation affect the rent vs buy decision?

Home appreciation is often overestimated. Historical average is about 3-4% annually (roughly matching inflation). In the short term (1-5 years), appreciation is unpredictable and can be negative. Don't buy expecting your home to be a great investment — buy for lifestyle stability if the numbers make sense.

What costs of homeownership do most people forget?

The biggest overlooked costs are: closing costs (2-5% at purchase), property taxes (1-2% annually), maintenance (1-2% annually), home insurance ($1,200-2,400/year), HOA fees ($200-500+/month), and selling costs (5-6% when you sell). These can add $15,000-25,000 per year on a $400,000 home.

Is renting better if I might move for work?

Yes, flexibility has real value. If there's a significant chance you'll move within 5 years, renting protects you from selling costs (5-6% of home value), potential market downturns, and the stress of selling quickly. Job mobility is one of the strongest reasons to rent.

Does the 5% rule for rent vs buy work?

The 5% rule (multiply home price by 5% and divide by 12 for monthly "true cost" of owning) is a good starting point but oversimplified. It assumes 3% opportunity cost, 1% property tax, and 1% maintenance — which may not match your situation. Use this calculator for a more accurate comparison with your actual numbers.

Should I buy a home as an investment?

Primary residences are mediocre investments. After accounting for all costs, mortgage interest, and inflation, most homes return 0-2% annually. Stock market index funds historically return 7-10%. Buy a home for lifestyle reasons (stability, customization, pride of ownership), not as a wealth-building strategy.

How much down payment do I need?

Conventional loans typically require 5-20% down. FHA loans allow 3.5% down. However, putting less than 20% down means paying PMI (Private Mortgage Insurance), which adds $100-300+/month. For the best financial outcome, aim for 20%+ down payment. On a $300,000 home, that's $60,000. Don't forget you also need 2-5% for closing costs on top of the down payment.

What is PMI and how does it affect buying?

PMI (Private Mortgage Insurance) is required when your down payment is less than 20%. It typically costs 0.5-1% of the loan amount annually ($125-250/month on a $300,000 loan). PMI protects the lender, not you, and adds to your monthly costs without building equity. It can be removed once you reach 20% equity, but it makes the early years of homeownership more expensive.

How does inflation affect the rent vs buy decision?

Inflation generally favors buying: your fixed-rate mortgage payment stays the same while rents rise. Your home value also tends to rise with inflation. However, high inflation often comes with high interest rates, which increases borrowing costs. The key metric is the real interest rate (nominal rate minus inflation). If real rates are low or negative, buying becomes more attractive.

Should I pay off my mortgage early or invest?

If your mortgage rate exceeds your expected after-tax investment return, pay it off early. At 6.5% mortgage rate vs 7% expected stock returns (roughly 5% after taxes), paying off the mortgage is nearly equivalent but with less risk. At lower mortgage rates (3-4%), investing the difference in index funds typically wins. Consider your risk tolerance and the guaranteed return of debt payoff.

What happens if home prices drop?

Falling home prices directly impact buyers: your net worth decreases while you continue paying the same mortgage. If you need to sell, you could lose your entire down payment or even owe more than the home is worth (underwater). Renters are completely unaffected by home price declines. This is one of the major risks of buying, especially short-term.

How do I calculate my price-to-rent ratio?

Divide the home price by the annual rent for a similar property. Example: $400,000 home / ($2,000 monthly rent × 12) = 16.7. Below 15 generally favors buying, 15-20 is neutral, above 20 favors renting. Major US cities range from 12-15 (affordable Midwest) to 25-35+ (San Francisco, NYC). This quick ratio helps before running detailed calculations.

Can I afford to buy a home?

General rule: your monthly housing payment should not exceed 28-32% of gross income (the 28/36 rule). You need at least 3.5-20% down payment plus 2-5% for closing costs and an emergency fund of 3-6 months of expenses. Realistically calculate all monthly costs: mortgage + property tax + insurance + maintenance + HOA. Many people underestimate the true monthly cost of ownership.

What are the tax benefits of homeownership?

US homeowners can deduct mortgage interest and property taxes (up to $10,000 SALT cap). However, since the 2017 tax reform doubled the standard deduction to $27,700 (married filing jointly in 2024), fewer homeowners benefit from itemizing. The tax benefit is smaller than most people think, especially with high mortgage rates where interest is high but you're also paying more overall.

Is it better to buy with a 15-year or 30-year mortgage?

A 15-year mortgage has lower rates (typically 0.5-0.75% less) and you pay far less total interest, but monthly payments are about 40% higher. A 30-year gives lower payments and more flexibility — you can invest the difference. Financially, a 30-year with disciplined investing of the difference often wins. But a 15-year forces savings and eliminates debt faster. Choose based on your discipline and cash flow needs.

Rent vs buy in a recession — what should I do?

Recessions typically favor renting: home prices may drop, credit standards tighten, and job security decreases. If you buy and then lose your job, you're stuck with mortgage payments. Renters have more flexibility to downsize or relocate for work. However, recessions can also create buying opportunities with lower prices. Wait until your employment and finances are stable before committing to a purchase.
