Formula
Buy Wealth = Home Value - Remaining Balance; Rent Wealth = Invested Down Payment + Invested Savings
The buy scenario tracks mortgage amortization, property appreciation, and all ownership costs. The rent scenario assumes the down payment and monthly cost savings are invested at a specified return rate. The option producing more net wealth at the end of the comparison period is recommended.
Worked Examples
Example 1: Mid-Range Home vs Apartment Rental
Problem:$350,000 home, 20% down, 6.5% rate, 30-year term vs $1,800/month rent increasing 3%/year. Compare over 10 years.
Solution:Down payment: $70,000 | Loan: $280,000\nMonthly mortgage P&I: $1,770\nMonthly owner cost (with tax/maint/ins): ~$2,326\nTotal buy cost over 10 years: ~$349,000\nHome value at year 10: $493,713 (3.5% appreciation)\nHome equity: ~$374,000\nRent total: ~$247,000\nInvested DP at 7%: ~$137,700
Result:Buy wealth: $374K vs Rent wealth: $200K | Recommendation: BUY
Example 2: Expensive City with High Rent
Problem:$600,000 home, 10% down, 7% rate, 30-year vs $2,800/month rent at 4% annual increase. Compare over 5 years.
Solution:Down payment: $60,000 | Loan: $540,000\nMonthly mortgage: $3,593\nOwner cost: ~$4,443/mo\nRent at year 5: $3,407/mo\nHome value: $712,154\nEquity: ~$187,000\nInvested DP: ~$84,153
Result:Buy wealth: $187K vs Rent wealth: $165K | Tight comparison at 5 years
Frequently Asked Questions
How does the mortgage vs rent comparison work?
Mortgage Vs Rent Decision Wizard Calculator compares the total cost and wealth accumulation of buying versus renting over your chosen time period. For buying, it calculates mortgage payments (principal and interest), property taxes, maintenance, and insurance, then tracks equity buildup through principal payments and home appreciation. For renting, it calculates total rent payments with annual increases and assumes the down payment and any monthly savings are invested in the stock market. The net wealth comparison shows which option leaves you financially better off, accounting for home equity, investment returns, and total costs paid.
How does home appreciation affect the buy vs rent decision?
Home appreciation is one of the most influential variables in this comparison. The national average home appreciation is roughly 3-4% annually over the long term, though this varies enormously by region. At 3.5% appreciation, a $350,000 home gains about $12,250 in the first year, and the effect compounds over time. Importantly, appreciation applies to the full home value, not just your down payment, which creates leverage: a 20% down payment on a home that appreciates 3.5% yields a 17.5% return on your initial investment. This leverage effect is why buying usually wins in high-appreciation markets, even when monthly costs are higher than renting.
What credit score do I need for the best mortgage rates?
A FICO score of 760 or higher typically qualifies you for the lowest advertised mortgage rates. Dropping from 760 to 700 can cost you 0.25-0.50% more in interest — on a $400,000 30-year loan, that difference costs roughly $60-$120 more per month and over $25,000 in extra interest. Scores between 620-699 still qualify for conventional loans but at noticeably higher rates. Scores below 580 generally require FHA loans, which accept down payments as low as 3.5% but mandate mortgage insurance for the life of the loan. Before applying, pay down revolving balances to below 30% of credit limits — this alone can boost your score 20-40 points.
How do mortgage points work?
Mortgage discount points are prepaid interest you pay at closing to permanently reduce your loan's interest rate. One point costs 1% of the loan amount — on a $350,000 mortgage, one point costs $3,500 — and typically lowers your rate by 0.20-0.25%. To determine whether buying points makes sense, calculate your break-even period: divide the upfront cost by your monthly savings. For example, $3,500 paid to save $55/month breaks even in about 64 months (5.3 years). If you plan to stay in the home beyond that point, buying points saves money. If you may sell or refinance sooner, keep the cash. Points are tax-deductible in the year of purchase for a primary residence.
