Rent vs buy a $650k house
Over 30 years, buying a $650k home comes out about $378,453 ahead — comparing buying (20% down, $130,000) against renting at $3,250/month and investing the down payment plus any monthly savings. Both paths start with the same money; the difference is where it goes.
Net worth over time: rent vs buy
Both start at age 30 with enough for the $130,000 down payment. The renter invests it (and any monthly difference) at 7%; the buyer puts it into a $650k home appreciating 3%/yr with a 30-year mortgage. In today's dollars:
| Age | Rent & invest | Buy |
|---|---|---|
| 30 | $164,390 | $161,051 |
| 35 | $384,035 | $420,744 |
| 40 | $648,614 | $731,403 |
| 45 | $967,658 | $1,104,050 |
| 50 | $1,352,742 | $1,552,015 |
| 55 | $1,817,849 | $2,091,356 |
| 60 | $2,379,881 | $2,758,334 |
What actually drives the answer
Rent vs buy is rarely about "throwing money away on rent." It hinges on a handful of levers this projection captures:
- Price-to-rent ratio. Here a $650k home is compared to $3,250/month rent. Where rent is cheap relative to prices, renting-and-investing can win; where buying is cheap relative to rent, owning pulls ahead.
- How long you stay. Buying carries big upfront costs (down payment, closing) that take years to earn back. The crossover in this scenario is around age 31. Move sooner and renting often wins.
- The invested difference. Renting only wins if you actually invest the down payment and monthly savings — not spend them. This model assumes you do.
Assumptions: 20% down, 6.5% mortgage, 30-yr term, 3% home appreciation, 1.1% property tax, 7% investment return, 3% inflation, single filer, no-income-tax state. Your local prices, rent, and how long you'll stay change the answer — model yours in the calculator.
What the down payment could have earned instead
At this price the cash required just to get in the door — a sizable down payment plus closing costs — is often the quietly decisive figure. Every dollar locked into home equity is a dollar no longer compounding in a diversified portfolio, and on a home this expensive that forgone growth adds up. The rent-versus-buy comparison only tilts toward renting when that freed-up cash, and any monthly savings, are actually invested rather than absorbed into everyday spending.
Equity also builds slowly at first, because early mortgage payments are mostly interest rather than principal. Buying carries real friction besides: closing costs going in, an agent commission going out, and ongoing maintenance that tends to run near one percent of the home's value a year. Those costs usually take several years to earn back — the familiar five-year rule.
The trade-off is genuine. A fixed mortgage locks your housing cost against inflation and quietly forces saving, while renting keeps a large down payment liquid and working elsewhere. Which comes out ahead depends mostly on how long you stay and whether the difference actually gets invested.
Common questions
Is it better to rent or buy a $650k house?
Over 30 years in this projection, buying comes out about $378,453 ahead — buying ends around $2,758,334 vs renting-and-investing around $2,379,881. It flips based on how long you stay, local price-to-rent, and whether you actually invest the difference.
How much do you need to buy a $650k house?
A 20% down payment is about $130,000, plus closing costs. Less than 20% down usually adds PMI. Renting frees that cash to invest instead — which is the core of the trade-off.
Does renting really mean throwing money away?
No. Rent buys housing without the costs of ownership (property tax, maintenance, transaction costs), and the down payment can be invested. Buying builds equity but ties up cash and assumes appreciation. Neither is automatically "throwing money away."
