Should I buy a home if I may move in three years?

If you may move in three years, compare buying and renting through that possible move date. Include purchase and selling costs, upkeep, the mortgage balance then due and an uncertain sale price. A smaller monthly loan payment alone cannot show which route leaves more money available.

The CFPB's homebuying preparation guide notes that a near-term move can make buying risky and expensive because of transaction costs. Your decision also includes what each home would make possible for the household; the site's home-and-the-week exercise explores that separate question.

Give both choices the same household

Use a wholly fictional comparison. The household has $100,000 assigned to housing and can supply another $2,100 at the end of each of the next 36 months. Other living costs and emergency money are funded separately. Both homes meet the household's stated needs equally for this financial exercise; utilities and the eventual moving cost are identical and paid from a separate common budget.

The rental costs $2,000 monthly plus $25 monthly renters insurance. A $2,000 deposit is paid at the start and returned in full at the end of month 36. There are no rent increases, fees or other differing rental costs in this example. Each month's unused $75 stays in cash.

The purchase costs $300,000: $60,000 down and a $240,000 mortgage. All purchase closing charges total another $9,000 paid at the start. The lender's supplied schedule requires $1,500 principal and interest monthly for the 36 months. Immediately after payment 36, the payoff amount is $225,000, with no extra accrued interest or payoff charge. These are invented quoted terms, not an interest-rate or market offer.

Ownership also requires $600 monthly in complete taxes, insurance and upkeep payments. Those costs are actually paid monthly under the supplied arrangements, with no separate escrow recovery or other balances at sale. Maintenance includes all required paid work; no unpaid owner labor supplies a hidden saving. There is no other differing cost.

Follow the money before the sale

The buyer pays $69,000 at the start: $60,000 down plus $9,000 closing costs. That leaves $31,000 cash. Monthly ownership payments use the entire $2,100 housing budget: $1,500 for the loan and $600 for everything else.

After 36 months, loan payments total $54,000. The supplied principal has fallen by $15,000, from $240,000 to $225,000, so $39,000 of the payments went to interest. Principal repayment is not rent or an additional cash asset; it lowers what must be paid from a later sale.

The renter pays the $2,000 deposit, keeping $98,000 in cash. Monthly rent and insurance use $2,025 of the same $2,100 budget. Saving the remaining $75 for 36 months adds $2,700. Immediately before the deposit returns, the renter has $100,700. After its return, cash is $102,700.

All cash earns zero in this comparison. There are no income taxes, investment returns or other cash flows. Adding them to a real analysis requires applying the relevant treatment consistently, not assuming that the renter spends money the buyer saves.

Use net sale proceeds, not the price

Assume the buyer sells immediately after payment 36 for the original $300,000. Complete selling charges are six percent of the sale price in this fiction, or $18,000. After those charges and the $225,000 payoff, the sale returns $57,000.

Add the $31,000 cash still held: the owner ends with $88,000. The renter's $102,700 is $14,700 higher under these assumptions.

A separate cost reconciliation reaches the same result. The owner paid $144,600: $69,000 initially plus $75,600 over 36 months. Receiving $57,000 back leaves $87,600 of net housing cash cost. Rental cost is $72,900: 36 times $2,025, with the deposit fully returned. The difference is $14,700.

This calculation has not treated the entire down payment or principal repayment as consumption. Both are reflected through the remaining loan and net sale proceeds. Subtracting another $15,000 for principal would count its benefit twice.

Test the sale price you are relying on

If the sale price is $285,000, six percent selling costs are $17,100. Net proceeds after the $225,000 payoff fall to $42,900. Adding the $31,000 held cash gives $73,900, which is $28,800 below the rental ending.

For buying to match the rental ending in this limited case, sale proceeds after costs and debt would need to be $71,700: $102,700 less $31,000. That requires a price of about $315,638 because 94 percent of the price, less $225,000, must equal $71,700.

That is a break-even input, not a forecast of appreciation. It does not prove the house can sell at that price or on that exact date. A delayed sale may leave mortgage and property costs continuing while the household also needs another home.

Choose the commitment you can carry

The household might still prefer owning for stability, control of its space or other reasons omitted by the matched-needs assumption. State those benefits honestly alongside the cost. A financial model cannot require you to value them at zero.

Before choosing, get the actual rental terms, loan and payoff schedule, purchase charges, maintenance evidence and realistic sale-cost assumptions. Run more than one sale price and move date, and check whether both the beginning and continuing payments are funded. Do not rely on a sale to supply money before it occurs.
