It could have taken the appraiser longer because there was not readily available data which met the lenders criteria. Its easy to turn an appraisal around quickly when the data is plentiful and readily available, not so when it is not. Many times the appraiser is forced to go to secondary or even third choices in searching for acceptable data.
The fact that "I was told by my mortgage agent that the appraiser had limited experience in this area", is more of an indictment on the lender that they chose to use that appraiser knowing this! Lenders like to throw it to the appraiser however the lender is ultimately responsible for the appraisal and the appraiser who performs it. If they knew the appraiser had only limited experience then you have to ask yourself why would they decide to use that appraiser?
Also keep this in mind, just because the appraisal did not support making the loan, does not mean the appraiser is at fault for the delay. Many times lenders will be, shall we say, less than truthful and not want to hear the appraiser saying ," there is limited data and it does not meet FHA guidelines or requirements so it will take some time for me to try some secondary sources for data".
Instead it becomes , the appraiser said it will take a little longer, the appraiser said it will be just a few more days, the appraiser said values not a problem. Then the Lender finally says, " Just give us the report with the data you have, I don't care what it is just give us a report!"
Only to receive the report and then be told by the underwriter it is unacceptable. They then use the excuse "the appraiser didn't do their job, I didn't know any of this, he just said it was going to take a little longer and value was fine"
Just one more thing. I don't know who told you it, but Well's is NOT the only lender doing FHA loans in your market.
While the appraiser may be wrong I tend to lean towards you are not being told the complete truth by the lender or AMC as to the communications from the appraiser.
The last time I informed a client the available data did not meet FHA guidelines, they still wanted the report with the best data available only to tell the agent and buyer "the appraiser couldn't appraise it out so we can't do the loan".
Well that wasn't the truth, the truth was at this time the sales data doesn't meet FHA guidelines. It's not the appraisers fault , we just report whats there. Some times those paid by commission just don't want to hear it and need to place blame.
