Double-Payment Reserve Calculator

Before you plan to carry both homes "for just a few weeks," see the number in full. Overlaps run long.

Move-Up and Timing

Direct answer

Buying before you sell can mean carrying two homes. Manageable - if you've sized the reserve honestly and assumed the overlap runs longer than hoped.

Work through the decision in order

What to check

Input 1 - Combined monthly housing costs (both mortgages + taxes + insurance + utilities). Input 2 - Overlap months (be conservative).

Your next move

Use the framework before the property creates urgency.

Bring the actual address, timing, financing assumptions, and open questions into a buyer strategy call before urgency takes over.

Questions about Double-Payment Reserve Calculator

Clear answers first. If one question changes the deal, bring it into the review before you move money.

Q1What does the Double-Payment Reserve Calculator help me decide?+

Overlap reserve is [output]. Add one month and re-check - buy-first plans go wrong when they assume the sale closes on schedule.

Yes. The decision framework is shared across all three markets. Address-specific pricing, rules, schools, taxes, insurance, and property facts still need live verification.
