These are a bunch of FEMA trailers but if they sell for under $2,000 pretty cheap since they are furnished and ready to be occupied.
They are in east texas area so need to figure out how much to have it delivered to your location.
Somebody should get a deal off of these FEMA things (can't really say what my opinion of FEMA is since we can't talk politics here) and if it is to be used just a few weeks a year there shouldn't be much of a formaldyhyde problem and that would probably all outgas over the next year anyway.
If you click on an individual trailer it shows some exterior and interrior shots. Heck new refrigerator and stove along with furniture would be worth more than some of the current bids.
