while i don't like ROVs i have found that the vast majority of them are really easy to deal with. case in point i got one today.
the subject was listed on the market for 110 days (very abnormal for my market when typical listing time currently is 30 days or less) @ $172,000, contract price was $180,000 with $8,000 in concessions (not hard to see what is going on here). i appraised it at $173,000 with 2 comps in the same development and one that was 0.75 miles away, all sales in the past 6 months. got the ROV and laughed out loud - it was written by the listing agent, emailed to the borrower who then emailed it to the lender but wasn't smart enough to redact all the info about the listing agent (advertising, sig line, etc).
so here i am telling the borrower (in a roundabout way) that they are overpaying for the property and they enlist the help of the person selling them the house to attempt to justify why they should be paying more than the house is worth. the 3 supplied sales, and they were not comps, were all 2-3 miles away, different styles of housing and all had more GLA than the subject (fwiw the subject was a split level, all comps were colonials). it took me less than 10 minutes to write my reply.
this was from a direct engagement lender who i have worked with for more than 13 years. they are a good client, so while they never really review these requests and just send them on to me i make the business decision to respond to them in a timely fashion. you will find that there are some good clients out there, and for those i go above and beyond, but they won't come knocking at your door. you have to learn the craft, establish yourself and then market yourself. the last bit is where most appraisers run into problems. there are far too many of us who think that because we have a license we are automatically entitled to work, and that work should be everything we think it should be. it doesn't work like that in real life. it took me a couple years to change my work from 100% residential lending to now only having 50% or less of my total workload. eventually i will be out of residential lending work completely, but it's where almost every residential appraiser cuts their teeth and some stay there forever.
