So as suggested, I emailed the appraiser after measuring my house. Following is the response I got back (Yes, he wrote all in caps):
THANK YOU FOR YOUR CONCERNS.
APPRAISALS ARE DETAIL IN NATURE BUT OBJECTIVE IN RELATION TO COMPARABLES. WITH ALL THAT YOU MENTIONED AND ASSUMING IT IS ACCURATE WE ARE ONLY TALKING ABOUT MAYBE $10-20,000 IN DIFFERENCE IN YOUR FAVOR.
IN SHORT, WE CAN GO BACK AND FORTH BUT THE BOTTOM LINE IS TRULY $10-20 MAYBE $30,000 IN DIFFERENCE WHEN CONSIDERING SQ. FOOTAGE DIFFERENCES AND OTHER LOCATIONAL DIFFERENCES.... NOT TO SAY THE NEW LISTINGS ON [my street - name redacted] THAT HAVE COME ON THE MARKET.
MORE OVER THERE ARE OTHER COMPS. NOT USED THAT CAN ALSO SUPPORT MY VALUE. I AM NOT IN BUSINESS TO COME IN LOW, JUST THE FAIR MARKET PRICE BASED ON FANIE MAE AND USPAP GUIDELINES.
I respect the opinions that you have all shared with me concerning this matter and I will take your advice about how I should proceed from here. I do not want to cause any trouble for anyone if I am being treated fairly, but to me this is an unacceptable response.
Just to respond to a few of the other suggestions I received: Yes, I plan on writing Cuomo about this and will share any response I receive. Also, I would talk to other banks, but I have a HELOC with my bank also, and I have heard horror stories about people trying to refinance their first loans with other banks in terms of getting the subornation on a timely basis.
