Denis,
The thought process is I think we take on more risk when we associate ourselves with certain types of assignments. Many appraisers feel FHA is a high liability/exposure type of assignment and have chosen not to complete that type of work as a result. I do FHA work.
Some feel complex properties open you up to more exposure. I live in a location where complex properties are a part of life.
Personally, I feel marginal borrowers and marginal properties can pose an uncomfortable level of risk. While I could care less about the FICO scores or employment history (not my business), I do care about the property condition when there is a greater chance of this loan going south. There's a greater chance everything about the file will be looked at under a microscope should the loan go bad. God help me if I missed the failing septic system that they carefully threw dirt over and hid with whatever they could....the weeds and debris is stacked up along the north side of the house such that you couldn't see the crack in the foundation....Can this happen with any place we look at? Of course it can, but the likelihood, in my opinion, is greater with B/C borrowers and their 'haven't had the money to fix it' properties. I will place my 'I'm not responsible for that which I can't see, not a professional in the field of plumbing, electrical, etc...' disclosures in my addendum, and cover myself as best as possible. Inspect as throroughly as I can, and by the grace of God, there go all of us who do these. It's not a wish of mine to make this type of deal a huge part of my business.
I'm not trying to be elitist or look down my nose at others. Hell, we've probably all suffered hard times at one point or another in our lives, and have needed a leg up a time or two. Everyone needs a place to live, and they all can't be the Taj Majal. But I also know I've been lied to or have had attempts at flat out deceipt by desperate people in desperate situations as well.
It has been my personal observation that 90% of the time, those who require a 'comp check' are what I consider the higher risk situations.
JMHO
So, fire away. If my thinking on this aspect is skewed, I'd be happy to hear your take.
