Waiting Calculator
Compare buying today with waiting, using assumptions you control. Results are estimates only.
What Could Waiting Actually Cost?
A lower future mortgage rate does not necessarily mean a lower overall cost. See how changes in home prices, rates, and equity can affect the numbers.

In Plain English
Under these assumptions, a $450,000 home would have an estimated value of $477,000 in 12 months. The hypothetical mortgage rate falls from 6.5% to 5.5%, and the future buyer would be financing a more expensive property. Buying today would also allow approximately $4,778 of mortgage principal to be paid during that period. After accounting for an assumed $4,000 refinance cost, the estimated financial opportunity associated with buying today is $27,778. These figures are hypothetical and depend entirely on the assumptions entered above.
The Rate Is Only One Part Of The Equation.
A future buyer may receive a lower mortgage rate but could also be purchasing a more expensive property. A current buyer could potentially benefit from appreciation and mortgage principal reduction and may have the option to refinance later if rates fall. This calculator allows you to change every assumption and see how the outcome changes.

How This Calculator Works
What Waiting for Lower Rates May Cost
This tool compares buying today, buying today and refinancing later, and waiting to buy, using the future rate and price assumptions you set.
What the inputs mean
Home price appreciation estimates how the price may change while you wait. Future rate is the rate you assume might be available later. Refinance costs cover what it may cost to refinance if rates fall after you buy.
How to read the results
The side-by-side table shows payments, loan amounts, and estimated APR for each path. A lower future rate on a higher future price does not always produce a lower payment. Estimated APR folds lender fees, discount points, and other prepaid finance charges into a single yearly cost figure, so it is usually a little higher than the note rate. Use it to compare scenarios, not as a quoted rate.
A note on forecasts
No one can reliably predict rates or prices. The tool is meant to show how the variables interact, not to recommend a timing decision.
