Should You Buy a House if You Might Move in 5 Years?

You’ve found a home you like, but you’re not sure you’ll stay more than a few years. Maybe a job change, a growing family, or just a desire to move. Should you buy anyway?

In most cases, no. Here’s why.

The transaction cost trap

Buying and selling a home is expensive. On a $500,000 home:

Buying closing costs (2-3%): $10,000-$15,000
Selling closing costs + commissions (6-8%): $30,000-$40,000
Total round-trip cost: $40,000-$55,000

That’s 8-11% of the home’s value consumed by transaction costs alone. To break even after these costs, your home needs to appreciate enough to cover them. At 3.5% annual appreciation, a $500,000 home gains about $17,500/year. It takes roughly 2.5-3 years of appreciation just to cover the costs of buying and selling, and that’s before you factor in mortgage interest, taxes, insurance, and maintenance.

Front-loaded interest compounds the problem

In the first 5 years of a $400,000 mortgage at 7%, you’ll pay approximately $135,000 in interest and only reduce the principal by about $22,000. That means 86% of your mortgage payments in those years go to the bank, not to equity.

Your total cash spent on housing in 5 years of ownership (mortgage, taxes, insurance, maintenance) will be roughly $160,000-$180,000. Your equity gained from principal paydown: just $22,000. The rest? Gone.

A realistic 5-year comparison

Let’s model a $500,000 home purchase vs. renting at $2,500/month:

Buyer after 5 years:

Home value (3.5% appreciation): $593,000
Mortgage balance remaining: ~$378,000
Gross equity: $215,000
Minus selling costs (6%): -$35,580
Net equity: $179,420
Total out-of-pocket (down payment + 5 years of costs): ~$280,000
Net gain: roughly -$100,000 vs. what was spent

Renter after 5 years (investing $100K down payment + monthly savings at 8% return):

Investment portfolio: ~$195,000-$220,000
Total rent paid: ~$160,000
Net position: portfolio value

In this scenario, the renter comes out ahead by $20,000-$40,000 or more, depending on exact assumptions.

When 5-year ownership can work

There are narrow scenarios where buying for a short period makes sense:

Extremely low price-to-rent ratio (below 12): The math shifts when buying is unusually cheap relative to renting
Below-market mortgage rates (under 4%): More of your payment goes to principal, less to interest
High-appreciation markets: If you’re confident in 6%+ annual appreciation (risky assumption)
House hacking: If you rent out part of the home, offsetting your costs

But these are exceptions, not the rule. For most people in most markets, 5 years is not enough time for homeownership to pay off.

The break-even timeline

As a general rule using current market conditions (6-7% mortgage rates, 3-4% appreciation):

Under 3 years: Buying almost never wins
3-5 years: Buying rarely wins, requires favorable conditions
5-7 years: A toss-up depending on local market
7-10 years: Buying starts to gain an edge
10+ years: Buying wins in most scenarios

If “I might move in 5 years” is on your mind, that uncertainty alone is a strong signal to rent. You can always buy later when your plans are clearer. You can’t easily undo a home purchase that locks you into a location you need to leave.

The flexibility premium

There’s an underappreciated cost to owning: reduced mobility. If a job opportunity appears in another city, a homeowner faces months of selling, potential losses, and emotional stress. A renter gives 30-60 days notice and moves.

That flexibility has real financial value. Studies by economists at the Federal Reserve Bank of New York have found that homeowners in declining job markets are less likely to relocate for better opportunities, leading to longer periods of unemployment and lower lifetime earnings.

If your timeline is uncertain, rent. The math is on your side, and so is the option value of being able to move when opportunity calls.
