I've looked on here and can't seem to find anything about it. I had a new client email a look up and said they needed $400K or more, wanted me to get back to them with the value and then they will order the full appraisal. I remember reading in USPAP that look ups are illegal and especially meeting a pre-determined value. Another appraiser in my office found something in 2004 USPAP saying it's okay as long as you disclose this is an appraisal, keep it 5 years, etc with lots of assumptions and could change upon the actual appraisal of the subject. I have noticed that many appraisers will not do look ups saying they are illegal but will do an appraisal if the client wants to order one. So, what is true?? What should I do? Is there a certain way to do them that makes it legal?
