Cost of Waiting

This model assumes that if you buy today, you are eligible for a no lending cost refinance after 12 months into the same rate assumed to be available one year from now. This allows the comparison to isolate the true cost of waiting: higher home price, lost equity growth, and delayed principal reduction.

Buy Now + No Lending Cost Refi vs. Wait 1 Year

This model assumes that if you buy today, you are eligible for a no lending cost refinance after 12 months into the same rate assumed to be available one year from now. This allows the comparison to isolate the true cost of waiting: higher home price, lost equity growth, and delayed principal reduction.

Note: The "Wait 1 Year" scenario automatically uses the same No-Cost Refi Rate above — ensuring both buyers receive the same future rate and the comparison fairly isolates only the cost of waiting.
