Housing Decision Guide
Rent vs Buy Explained
Buying can build wealth, but ownership also carries expenses that never come back. The right comparison is not rent versus mortgage payment. It is rent versus the full stack of ownership costs and benefits over the years you expect to stay put.
What matters most
- Time horizon is often the deciding variable.
- Owning creates both recoverable equity and unrecoverable costs.
- A good model should include maintenance, taxes, appreciation, and the opportunity cost of your down payment.
Holding-period comparison
$425,000 home, 20% down, 6.5% mortgage, $2,200 starting rent, 3% rent inflation, 3% appreciation, 1.2% tax, $1,500 insurance, 1% maintenance, 3% buy closing, 6% selling costs.
| Horizon | Cumulative rent | Modeled ownership cost | Advantage (rent minus ownership) |
|---|---|---|---|
| 3 years | $81,600 | $98,939 | $-17,340 |
| 5 years | $140,161 | $136,089 | $4,072 |
| 7 years | $202,289 | $170,299 | $31,990 |
| 10 years | $302,646 | $215,478 | $87,168 |
Positive advantage means the rent path costs more than the ownership path under these assumptions. The starter table uses a 0% alternative-return assumption. A non-zero rate is a hypothetical cost of cash tied in the down payment and buyer closing costs, not a guaranteed return.
Monthly payment is only the headline
A mortgage payment can look close to local rent and still produce a very different long-term outcome. Ownership includes property taxes, maintenance, insurance, transaction costs, and the cost of committing cash to a down payment.
That is why a credible rent-versus-buy comparison needs more than one monthly number. It needs a time horizon and a net-worth lens.
Unrecoverable ownership costs deserve more attention
Not every dollar of a mortgage payment builds equity. Interest, taxes, insurance, and maintenance are costs you do not get back. Equity growth comes from principal paydown and appreciation, but it takes time for those forces to overcome the upfront cost of buying.
For shorter stays, those unrecoverable costs can make renting the cleaner financial choice even when homeownership feels more permanent or prestigious.
- Closing costs and future selling costs compress near-term ownership returns.
- Maintenance is irregular, which makes ownership feel cheaper than it really is if you under-budget it.
- Opportunity cost matters when your down payment could have stayed invested elsewhere.
Why the time horizon often decides the result
If you expect to move in three to five years, buying has less time to recover upfront friction. If you expect to stay longer, appreciation and principal paydown have more space to compound in your favor.
A strong model is not trying to predict the housing market perfectly. It is helping you see how sensitive the decision is to assumptions you can actually control, especially holding period and budget tolerance.

Assumptions to check before using the estimate
| Assumption | How to verify it |
|---|---|
| Time in home | The comparison ends when you sell, so the holding period sets every total. |
| Unrecoverable costs | Interest, property tax, insurance, maintenance, and closing and selling costs. |
| Opportunity cost | The down payment and closing costs could earn a return if you rented instead. |
Common mistakes this guide helps avoid
- Comparing rent with the mortgage payment alone.
- Counting the whole home value as wealth instead of equity after selling costs.
- Leaving the alternative return at zero when you would invest the cash.
When this estimate may be misleading
- Home appreciation and rent growth are assumptions, and small changes can flip the answer.
- PMI is not modeled, so buyers putting less than 20% down pay more than shown.
Frequently asked questions
Does buying always build more wealth over time?
No. It often does over longer holding periods, but the answer changes with local rent levels, home prices, taxes, maintenance, rates, and how long you expect to stay.
Why does the calculator care about appreciation assumptions?
Appreciation influences future equity, which is one of the main financial benefits of owning. Small changes there can materially affect the long-run comparison.
