Can we buy the next house now and put the sale money into the mortgage later?
The tool is called a recast, and it's one of the most useful moves almost nobody explains. You close on the new house with a bigger loan, sell your old house, then hand the proceeds to your lender as a lump sum. They re-amortize: same rate, same end date, meaningfully smaller payment. The fee is usually a few hundred dollars, not a refinance.
Two checks before you count on it. Not every loan allows recasting — confirm in writing before closing, because the ones that don't can't be talked into it. A recast keeps your existing rate, which cuts both ways. It helps when your rate is decent; it's no help if rates have fallen since you closed — that's a refinance question instead. Your lender owns the fine print; I own the sequencing.
For anyone buying before selling, this is the piece that makes the bigger interim payment bearable. Ask about it on the first lender call, not the last.
