Cynthia,
Brad - gee, I didn't know that my H&B use analysis was supposed to be so detailed as to include/exclude features of the structure. If I determine that the H&B use is SFR, I don't get down to the number of bedrooms or verifying that the plans met the permit etc. Was the addition legally permissable? If it was NOT permitted, (records that far back aren't always complete) could it be brought up to code? Many questions to ask, but I never knew that H&B use considers whether you got permits for your addition.
If the loan goes bad, and the lender is forced to cure code problems that were nown and apparent, tear down unpermitted portions of the improvments, etc. etc. you would not be a happy camper.
I am helping to prepare a case right now specifically on this issue. One of the issues will be highest and best use.
The municipalities have lots of power over structures- not the least of which is to issue retro permits with really big fines, refuse them (and then what do you do- since you are not going to be able to
force them to issue a retro permit?), cite the illegal addition or conversion for demolition, etc.
I have one in LA where the borrower illegally converted it into a triplex. The city is willing to allow a duplex but the 3rd unit must be undone. It is zoned SFR. To complicate matters, all units were occupied by illegals and to evict them was not easy (there are actually CA laws that make that difficult) and it was far easier to to pay a ton of key money (yep they got a lawyer) to get them out.
Do you think I will not cite that the appraiser ignored H+B use due to illegal conversions and add on the key money to a claim?
Now, of course, you could cover this all with an EA- but on the forms in which you detail your scope such an EA is not permitted if your scope was a Fannie compliant assignment.
So, yes your analysis should be that detailed. This no different than a home having a granny unit that is illegal. It may add value to the typical buyer but H+B use will not be for it to have one.
I have seen cities go from requiring the decommission and capping of a second kitchen all the way to actually demolishing the entire home.
