Will the bank count our current mortgage against us when we buy the next house?
Most lenders count both payments against you — until your current house is sold or under a solid contract. It's the single biggest surprise for move-up buyers, and it's why strong households sometimes hear a 'no' that feels wrong.
The ways through are specific. A closed sale clears it completely. A signed purchase agreement on your house often lets the lender drop the old payment, depending on the program. Strong reserves — months of both payments in the bank — widen what underwriting accepts. Rental income on the departing house can count, but usually only with an executed lease in hand, not a plan to find a tenant. (Every program draws these lines differently; your lender walks you through the exact ones.)
The strategy answer: get pre-approved for the carry-both scenario before you fall for a house. If you qualify carrying two, everything after that is easier than you feared.
