My walk-out basement has several large windows (32x50) above grade and a door leading to two steps to the door to the yard. The area is finished and heated and cooled with another staircase leading to the kitchen. We are relocating and the appraiser won't base upon 1916 sq ft to include the bsmt. This is obviously greatly affecting our appraisal amount and I'm trying to find any possible way to include this sq footage.
