Rent vs. Buy: How to Run the Numbers for Your Market

Deciding whether to rent or buy means comparing two sets of real costs over a defined time horizon -- not feelings about ownership or conventional wisdom about throwing money away. The core calculation weighs your total cost of renting (rent plus renters insurance plus fees) against your total cost of owning (mortgage principal and interest, property taxes, insurance, maintenance, and transaction costs) over the period you plan to stay, then asks which path leaves you with more money at the end.

The True Cost of Renting

Rent is the most transparent housing cost you will encounter. You write a check, you get a place to live, and you get your deposit back if you left the unit in good shape. That simplicity is one reason calling rent "wasted money" misses the point: rent buys a service -- housing, maintenance handled by someone else, and the legal right to leave when your lease ends.

Still, the full cost of renting runs slightly above the monthly figure. A complete accounting includes:

• Monthly rent -- the base figure
• Renters insurance -- typically $15 to $30 per month, according to the National Association of Insurance Commissioners, covering personal property and liability that a landlord's policy does not extend to tenants
• Application and move-in fees -- often one to two months' rent upfront (first month, last month, security deposit), depending on your state's rules
• Annual rent increases -- the U.S. Census Bureau's American Housing Survey has historically tracked these in the 3 to 5 percent range per year in most metros, though it varies by city and lease

What renting does not cost you: property taxes, mortgage interest, homeowners insurance on the structure, HOA dues, roof repairs, HVAC replacements, or the 5 to 6 percent agent commission you would owe when selling. Those costs belong to your landlord.

Renting also preserves optionality. If your job, family, or neighborhood changes, you can leave at lease end. That flexibility does not show up in a spreadsheet, but it has real financial value if the alternative is being forced to sell at a bad time.

The True Cost of Owning (Including Hidden Costs)

The sticker price of homeownership is the mortgage payment. The real price is considerably higher.

Mortgage principal and interest is the figure most buyers use to compare renting and buying. On a $400,000 home with 10 percent down ($40,000) and a 30-year fixed-rate mortgage at 7.0 percent -- near the 2024-2025 range tracked by Freddie Mac's Primary Mortgage Market Survey -- the principal-and-interest payment is about $2,393 per month. The first payment splits roughly $2,100 to interest and $293 to principal: in a mortgage's early years, most of your payment is interest, not equity.

Property taxes vary by state and county. The Tax Foundation reports effective rates from under 0.3 percent of assessed value in Hawaii to over 2.0 percent in New Jersey and Illinois. On a $400,000 home at a 1.1 percent effective rate (close to the national average), that is $4,400 per year, or about $367 per month.

Homeowners insurance typically runs $1,000 to $2,000 per year on a $400,000 home, according to the Insurance Information Institute, though coastal, older, and high-risk properties run higher.

Private mortgage insurance (PMI) applies if your down payment is below 20 percent and costs 0.5 to 1.5 percent of the loan annually, according to Freddie Mac. On a $360,000 loan at 0.8 percent, that is $240 per month until you reach 20 percent equity.

HOA fees apply to a condo, townhome, or home in a planned development. The Community Associations Institute estimates the average monthly condo fee in metro areas at $300 to $400, though the range is wide.

Maintenance and repairs are the cost most often omitted from these comparisons. Freddie Mac suggests budgeting 1 to 2 percent of a home's price per year -- $4,000 to $8,000 annually on a $400,000 home, or $333 to $667 per month for appliances, roof, plumbing, HVAC, and paint. The American Housing Survey confirms homeowners routinely spend in this range over time.

Transaction costs at purchase are a one-time but substantial expense. Closing costs typically run 2 to 5 percent of the loan, according to Freddie Mac -- $7,200 to $18,000 on a $360,000 loan, due at the table on top of your down payment. See our guide to Closing Costs Explained: What Buyers Actually Pay for a line-by-line breakdown.

Transaction costs at sale add another layer. Agent commissions have traditionally run 5 to 6 percent of the sale price, though buyer-agent compensation shifted after the National Association of Realtors settlement that took effect in August 2024. Even at 4 to 5 percent total, that is $16,000 to $20,000 on a $400,000 sale -- money out of your equity before you net a dollar.

The Break-Even Horizon Concept

The break-even horizon is how long you must stay before your total ownership costs (including transaction costs at entry and exit) drop below what you would have spent renting. Before that point, renting is mathematically cheaper. After it, ownership typically wins -- if your home has appreciated and you have built meaningful equity.

The concept matters because homeownership is not inherently superior to renting -- it is superior if you stay long enough. Most analyses, including those from the Urban Institute and the CFPB, put the typical break-even horizon between three and seven years, with the range driven by:

• Closing costs -- higher upfront costs push the horizon out
• Mortgage rate -- higher rates send more of each early payment to interest instead of equity
• Local appreciation -- faster-appreciating markets shorten the horizon; flat or declining ones extend it
• Rent trajectory -- if local rents are rising fast, buying looks better sooner

The price-to-rent ratio is a useful first screen for where your market sits. Divide a home's purchase price by its annual fair-market rent equivalent. Drawing on Zillow Research and analysis published by the National Bureau of Economic Research, ratios below 15 historically favor buying, 15 to 20 require careful individual analysis, and above 20 generally favor renting unless you stay long-term. Many high-cost markets (San Francisco, Seattle, New York) run above 25, meaning buyers need a very long horizon for ownership to win on pure numbers.

When Renting Wins

Renting is the financially sounder choice under several identifiable conditions -- not as a consolation prize, but as a deliberate outcome.

Short time horizon. If you expect to relocate within three to four years, buying is likely to leave you behind. Upfront transaction costs alone (closing costs plus eventual sale commissions) can run 8 to 10 percent of the purchase price across both ends -- a gap that appreciation and equity rarely close in under four years in a flat market.

High price-to-rent ratios. Where buying a comparable home costs 22 to 30 times annual rent, renting and investing the difference (in a diversified index fund, say) has historically produced comparable or better outcomes over 10-year periods, according to opportunity-cost research published by the National Association of Realtors Research Group.

Income volatility. Ownership concentrates financial risk. If your income is variable -- freelance, commission-based, or cyclical -- the fixed obligation of a mortgage, taxes, and insurance is a structural liability that renting does not impose. For this reason the CFPB recommends total housing costs (mortgage plus taxes plus insurance) stay under 28 percent of gross monthly income.

Lifestyle flexibility. If your life requires the ability to move on short notice, ownership is a constraint. That is not a flaw in renting; it is the product working as intended.

When Buying Wins

Buying produces better outcomes under a different set of conditions -- again, identifiable and worth specifying rather than asserting.

Long time horizon in a stable or appreciating market. If you plan to stay seven or more years, the amortization math works in your favor: you build equity with each payment, upfront costs spread across a longer period, and appreciation (if present) compounds. The Urban Institute's Housing Finance Policy Center has documented that ownership's wealth-building advantage over renting increases substantially beyond the seven-year mark.

Below-average price-to-rent ratios. Many secondary markets in the Midwest and Sun Belt run in the 12 to 18 range, where buying pencils out far earlier. Columbus, Indianapolis, Memphis, and several Texas cities have traded there in recent years, according to Zillow Research's metro-level data.

Rate lock in a rising-cost environment. A fixed-rate mortgage locks your principal-and-interest payment for 30 years. Where rents are rising 5 to 8 percent annually, that fixed payment grows comparatively cheaper each year. See our guide to Down Payment Requirements by Loan Type (2026) for how loan structure affects your monthly obligation and long-term cost.

Equity as forced savings. For buyers who would not otherwise invest the rent-versus-own difference, the forced-savings effect of a mortgage has real value. Each principal payment cuts your balance and builds equity -- a return renting does not provide, even though disciplined investment of the savings could theoretically match it.

Stability in daily life. The intangible benefits -- the freedom to renovate, security against non-renewal, the roots of longer tenure -- are real even if they do not appear in a spreadsheet. Name them honestly, without inflating them into a financial argument they do not fully support.

How to Run Your Own Numbers

Running the comparison for your market requires six inputs. No online calculator can do this without all six, and most use national averages that bear little resemblance to your situation.

Step 1: Establish your true monthly rent cost. Take your current or prospective rent and add renters insurance. Estimate a realistic annual increase -- ask what the landlord has charged in prior years, or check the Bureau of Labor Statistics rent index for your metro area.

Step 2: Calculate your full monthly ownership cost. Use Freddie Mac's current benchmark rate from its weekly Primary Mortgage Market Survey (published Thursdays at freddiemac.com) to model principal and interest. Add property tax (from the county assessor's website), a homeowners insurance quote, PMI and HOA if applicable, and a maintenance reserve of 1 to 2 percent of price divided by 12.

Step 3: Model the gap. Subtract monthly rent from monthly ownership cost. In the early years, that gap is what renting saves you each month. The question is what happens to it over time -- and what you would do with it.

Step 4: Add transaction costs to the ownership side. Pull closing costs from your lender's loan estimate (required by law within three business days of application, per the CFPB); our guide on Closing Costs Explained: What Buyers Actually Pay walks through each line. Add expected sale costs at exit -- typically 4 to 6 percent of the sale price.

Step 5: Estimate appreciation. Be conservative. The Federal Housing Finance Agency's House Price Index is a reliable historical reference, and regional Fed banks often publish market-specific forecasts. Avoid peak-market numbers from any single exceptional year. Run your figures at zero appreciation and at a modest 2 to 3 percent to see how sensitive your break-even is.

Step 6: Compare cumulative totals at your time horizon. Sum the total cost of renting over your planned stay. Sum the total cost of owning, minus the equity you will have built (principal paid down plus appreciation, less sale costs). The path with the lower net cost is the better choice -- for your numbers, in your market, at your timeline.

The rent-vs.-buy decision is not universal. It is specific to your income, savings, time horizon, local market, and tolerance for the risks on each side -- maintenance and downturns when you own, rent volatility and relocation disruption when you rent. Running the numbers honestly, with real inputs and named sources, is the only way to get an answer that is actually yours.
