Fannie Mae expressly forbids appraisers to include the square footage of a new ADU into the "Gross Living Area" of the property. That's why an average appraiser may give a $0 value to a 1200 square foot ADU.
We partnered with the Appraisal Institute to train our Appraisers on how to properly value ADU - and see the difference! #ADU#appraisal
