Can I sell my home if I still have a mortgage?

Having an existing mortgage does not stop you from selling a home, since the payoff amount simply comes out of the sale proceeds at closing, the same as any other lien. Your closing attorney orders a payoff statement from your lender and pays it directly from the funds the buyer brings. If the sale price does not cover the full payoff, that is a conversation your agent should flag early, not something you discover at the closing table.
