This might seem like a unique property, but actually, after looking at dozens of properties at the very lowest end of the price curve a definite pattern emerges in the pricing of homes similar to this. It is not that difficult to establish the value of the land, the value of the garage, and the value of the trailer. There are comparable sales that match one two of these vectors, and by comparing several sales with varying degrees of similar features and amenities, a triangulated value can be established. Whatever this buyer and sell end up agreeing on as the fair market value, it will impact future sales moderated by whatever factors are determined to have made the price go up or down regarding the expectation based on previous sales.
I am not going to link with all the videos that are in the data pool. I will just summarize:
Land Value- $100,000 to $125,000
Garage Value- $35,000 to $50,000
Trailer Value- $25,000 to $50,000
The land value and the garage value are easy to establish, the value of the trailer will depend on inspections and investigation. My visual inspection put it in a range that could be as high as $50,000 or as $25,000. If you take the high value on all three vectors, the price would be $225,000. The low value is $160,000. The rest will be determined by a buyer making a real offer and the seller responding.
