Pam,
Have been thinking about your challenge and your client's plight since yesterday......hmmmmm.
In addition to all the appraisal stuff, is there a "Consumer Watch/People Helper" reporter at the local TV station? (They're big in the Seattle area -- every station has one.) These people obviously got screwed. I agree with Chris that if a history of water supply has been established over the years, there might be an "adverse possession" situation. I also agree that what you're uncovering should go straight to the attorney general. The $1900 extra to the appraiser is unconscionable.
This is a case where suddenly, you've been thrust into a situation where you're being challenged to become more than an appraiser.
I fully believe that unethical, unscrupulous and fraudulent appraisers ought to be left twisting in the breeze for the vultures--along with the real estate agents and lenders who employ, enable, and encourage them,
BUT
I wonder if we aren't turning a critical corner by making the appraiser responsible for the legality of the water supply.
I consider myself reasonably adept at reading legal descriptions and title reports, but some of the "subject to's" in legals are next to impossible to decipher. We have a lot of shared wells up here and not all of them are written up in the legal description. I have to admit that, on occasion, I have taken the word of the homeowner and/or realtor because the reality of taking the time to got through all the legals (and that means researching each and every one of the documents which make up the "subject to's and any documents referenced therein) and then verifying everything with the county health/environmental resources dept. would result in the production of one appraisal a week or less!!
So (and not to defend this appraiser of yours), there are times when I look at a situation like this water issue and think "There, but for the grace of God, go I". Of course, if someone says it's town water and we're on the other side of the island, I'll know something's fishy, but, by and large, it's not realistic to think that in the scope of a URAR (much less a limited/summary 2055) you can research and verify every single item. That's the reason for the standard assumptions and limiting conditions. The agent has definite responsibility here, as does the seller as does the title company.
Now that I've stirred the pot some, I wish you the best with this difficult assignment. I'll also bet that it's one of those you will voluntarily be undercompensated for -- as you mentioned in a post I read this morning.
Good luck! We're all behind you.
Nancy
