Appraised value appeals

[Anita Fulton]

Help bigger pockets family! I’m attempting to do a cash out refi on my home that I purchased in 2005 for $749k in the champions area of northwest Houston. The appraised value came in at 633k.  The appraiser used comps in spring which is a totally different neighborhood.  Is this standard for a property to drop in value over 100k over a 15 year period? There is no structural damage, no flooding, etc and the appraiser stated the home was in good condition. What do I do to appeal the appraisers’ report? Clearly there was a mistake in his calculations.
