I think you're trying to fit a square peg into a round hole.
True, it has no functional or external depreciation. I'm a little gun shy on using those. I had an UW the other day who challenged my use of functional obsolescence in a similar situation. "How do you know there is FO? How did you calculate the FO?" If someone can help me with language to justify a functional or external obsolescence I would be very appreciative.Your cost approach is not considering functional or external depreciation. It is considering only physical depreciation.
Those are the comps that best match the condition and characteristic of the subject property. There aren't any that are higher priced in the same condition within a reasonable distance. In this area developers are buying up lots and replacing the homes with 4-8 unit detached townhomes. So $225k for a 20,000 sf lot is a bargain for them.
We can't distort the apprasial in order to avoid "deep sixing the loan." That said if the subject contribution is 5k to a land value of 225 k HUB is a teardown and then the HBU is not the current use it is as vacant siteFHA reverse mortgage. 1955 house on 20,000 sf lot. House has some unfinished work, missing door casings, etc. but pipes and wiring were replaced. Definitely livable. Sales price of comps is $215K, 214K, 212K, 155K, and 245K. Adjusted values are $232K, $237K, 241K, 210k, and 228k. My value opinion was $230k. Cost method comes in at $320k, mostly because site value is $225k. Five solid comps for land value between $190,000-235,000. UW is questioning land value. Have already set the effective age to 30 years so I cant get any more depreciation for cost approach without deep-sixing the loan. Any suggestions on how to reconcile the two approaches or explain to UW?
