What's Your Home Actually Worth as an Investment?

Ask someone how much money they made on their home and you'll almost always get the same answer: sale price minus purchase price. A couple buys a house for $320,000, sells it twelve years later for $510,000, and tells everyone they made $190,000.

They probably didn't.

The gap between what people think their home returned and what it actually returned is one of the most persistent blind spots in personal finance. And it matters — not because homeownership is a bad decision, but because making a major financial commitment with the wrong mental model is how people end up surprised.

The $190,000 gain above looks compelling until you start accounting for where the money actually went over those twelve years.

Interest paid on the mortgage. On a $256,000 loan at 6.5% over 30 years, you pay roughly $325,000 in total — more than the loan itself. If you sell after 12 years, you've paid the bank approximately $185,000 in interest, and only a fraction of that has gone toward paying down the principal. This is the single largest hidden cost most homeowners never add up.

Property taxes. As a rule of thumb, property taxes average around 1.25% annually of a home's assessed value.¹ On a $320,000 home over 12 years — with taxes rising each year — you're looking at $55,000 or more paid to the municipality. That money is gone at sale.

Maintenance and upkeep. Homeowners spend an average of $21,000 per year to maintain their property.² Even using a conservative 1% of home value annually as a baseline, twelve years of maintenance on a $320,000 home adds up to $38,000+.

Closing costs — twice. You paid 2–3% to buy. You'll pay another 5–6% in realtor commissions and closing costs to sell. On a $510,000 sale, that's roughly $30,000 off the top.

Add it up: $185,000 in interest + $55,000 in taxes + $38,000 in maintenance + $30,000 in selling costs = $308,000 in true costs of ownership. Against a nominal gain of $190,000, that's actually a net loss on paper — before even accounting for any renovations.

This isn't a knock on homeownership. It's a reminder that the math is more complicated than most people run.

Housing is the most unique of all financial assets. Over the life of your loan you have to pay interest, insurance, property taxes, maintenance and upkeep. The frictions are enormous.³ But — and this is critical — those frictions become less punishing the longer you stay.

Here's why: interest payments are front-loaded. In the early years of a mortgage, almost every payment goes to the bank, not to your equity. By year 5 on a 30-year loan at 6.5%, you've built roughly 8% equity through principal paydown. By year 15, it's around 26%. By year 25, you're over 60%. The longer you stay, the more favorable the math becomes.

The same logic applies to transaction costs. Paying 8–9% in combined buying and selling costs to flip a home in two years is financially devastating. Spreading those same costs over 20 years of ownership makes them nearly irrelevant.

Both real estate and stocks have yielded similar inflation-adjusted returns of around 5% annually over long periods — but they achieve this via very different paths.⁴ Real estate's return is heavily dependent on holding period, leverage, and location. A homeowner who bought in Phoenix in 2000 and held through 2025 likely did very well. Someone who bought in 2006 and sold in 2012 almost certainly didn't.

From 1991 to 2024, U.S. single-family homes experienced average annual appreciation of approximately 4.3%.⁵ That sounds reasonable — but it's a national average that masks enormous regional variation, and it doesn't account for any of the costs described above.

Stocks have returned, on average, about 8% to 12% per year while real estate has generated returns of 2% to 4% per year.⁶ The leverage inherent in a mortgage can boost those real estate returns significantly — but only if the home appreciates and only after accounting for true costs.

A property purchased for $153,500 in 1995 would have grown to $503,800 by year-end 2024. The same amount invested in the S&P 500 would have grown to more than $3.4 million.⁷ This isn't an argument against homeownership — you have to live somewhere, and the S&P 500 doesn't give you a place to raise your kids. But it is an argument for going in with clear eyes about what a home is and isn't as a financial asset.

A primary residence is not a pure investment vehicle, and it shouldn't be evaluated like one. It's a forced savings account — every mortgage payment builds equity you'd otherwise spend on rent. It's an inflation hedge — your payment is fixed while rents rise around you. It provides leverage — you control a $500,000 asset with a $100,000 down payment. And for most families, it provides stability, roots, and the ability to build something that can be passed on.

It's impossible to compute the psychic income you get from owning a home in the neighborhood and school district you desire.³ The financial return is only part of the story.

But the financial return still matters — and most people are calculating it wrong.

We built a free tool specifically for this: the True Cost of Homeownership Calculator at canweaffordthis.com.

Enter your purchase price, down payment, interest rate, annual property tax, maintenance budget, renovation plans, and how long you plan to own — and it shows you the full ledger: total interest paid, taxes paid, maintenance costs, renovation spend, and your estimated net position at sale across three appreciation scenarios (conservative, expected, optimistic). It also factors in extra principal payments if you're planning to pay down the loan faster, and shows exactly how many years early you'd pay it off.

The point isn't to talk you out of buying. It's to help you go in knowing exactly what you're signing up for — so the number you tell people in twelve years reflects what actually happened, not just the sale price minus the purchase price.

If you're also thinking through the monthly cash flow on a potential purchase — whether the payment fits your budget alongside your other expenses — the main Can We Afford This? simulator runs that analysis too. Free, no signup required.

What is the average ROI on a home? It depends heavily on location, holding period, and how you define ROI. Nominal home price appreciation has averaged around 4–5% annually in the U.S. since the early 1990s, but true ROI after accounting for interest paid, property taxes, maintenance, and transaction costs is significantly lower — and can be negative for short holding periods.

How long do you need to own a home for it to be a good investment? Generally, the longer the better. Short-term ownership (under 5 years) is typically unfavorable because transaction costs alone consume a large portion of any appreciation. Most financial advisors suggest planning to own for at least 7–10 years for the math to work meaningfully in your favor.

What costs reduce ROI on a home? The major ones: mortgage interest (often more than the loan principal over 30 years), annual property taxes, maintenance and repairs (typically 1–2% of home value per year), homeowners insurance, and transaction costs at both purchase and sale (combined 8–10% of the home's value).

Does paying extra principal improve ROI? Yes — significantly. Extra principal payments reduce the total interest paid over the life of the loan, build equity faster, and lower the remaining balance at sale. Even modest extra monthly payments can save tens of thousands of dollars in interest over a 30-year mortgage.

Is buying a home better than renting and investing? It depends on your situation, time horizon, and local market. Historically, stocks have outperformed real estate in pure return terms, but homeownership provides leverage, stability, and forced savings that investing alone doesn't replicate. The right answer is personal and depends on your specific numbers.
