Question one: how much equity walks out the door after the sale closes. Question two: what does the monthly cost actually look like in the next home, including taxes, HOA, insurance, and the loan.
The first one is the Pocket Cash calculator. It runs your sale price against your loan payoff, closing costs, and concessions, and gives you the net cash you would have in hand. The second one is a quick lender conversation, which on this site means me.
One quiet detail most people miss: if you have lived in the home as your primary residence for at least two of the last five years, the IRS capital gains exclusion is $250,000 single or $500,000 married filing jointly. For Hurricane homeowners who bought before 2018, that exclusion is often the difference between a clean move and a tax bill. Worth a Capital Gains Estimator run before you list.
