Hello, I am currently working on a 1004 for a large bed and breakfast in the Wasilla-Palmer area in Alaska
The fact that you describe this as a 1004 assignment means the lender assigned it as a residential SF property (which it may or may not be). Owners of mixed use or dual use properties want the lower interest rates of a residential loan, so they apply for, and hope to get, a res loan by passing their property off as a house for personal use with the commercial use more like a hobby..
Whether or not they get the loan is not your problem, but it shows why it was assigned by the lender as a res property, they also want to push the loan through as such.
Next question then is HBU...either you, as a res appraiser are familiar enough with the area and can make some form of study to find a supportable opinion, or you can't.
Do a quick sales comparison, if the data is there...what are B B's selling for, compared to similar size SFR? What is the marketing times of each? If the land were vacant, which type of buyer would most want that location? This property would need $ to convert it back to res use, is the location or land so desirable that it still would appeal to a res buyer?
If sounds extensively improved for B and B use, with a commercial kitchen, bedroom configuration for large groups, and lighted ski trails. The typical B and B is more or less a charming house with some changes made with bedroom egress to accommodate guests. This subject sounds almost more like a hotel or lodge ...is the owner might be trying to pass it off as a B and B to qualify for a res loan ?
