How to read it
Today’s payment: $2,528. Future payment if you wait: $2,734. The cost of waiting captures both higher prices and any rate changes you expect.
Counterargument: if rates drop while you wait, the future payment can be lower. Run multiple rate scenarios. Also consider the rent you'd pay during the wait period — that's a real cost too.
How to Use
- Enter today's price and your expected appreciation rate.
- Enter how many years you'd wait.
- Enter your down payment percent and current vs future rate assumptions.
- Read the monthly cost of waiting and lifetime interest impact.
Frequently Asked Questions
What if rates drop while I wait?
Run the future rate as lower than current. If the savings from a lower rate exceed the extra cost from appreciation, waiting wins. In rate-cut environments, waiting can be the right call.
How accurate are appreciation forecasts?
Long-term US home prices have averaged 3–5% appreciation but with significant year-to-year and regional variation. Use a moderate assumption (3–4%) for a reasonable baseline; bullish or bearish markets warrant adjustment.
Should I include rent paid during the wait?
Mathematically yes — that's pure cost during the wait period. The cost-of-waiting picture is incomplete without comparing to rent paid vs principal paydown plus appreciation if you'd bought now.
What if I don't have the down payment yet?
Then waiting is forced — but the appreciation still hurts. Run scenarios with smaller down payment options (10%, 5%, 3.5% FHA) to find an entry point sooner.
