Cool building for sure. But if it was bought for $35g's and now they want $97g's, I would really like to know where they are coming up with that figure at given the economy is pretty much in the tank as far as housing goes.
You can get on the County Auditors website and see the particulars about it as far as what it sold for, improvements, and so on.
It looks great, the foundation can be repaired, some of the building shows it needs insulation. Use all of that to your advantage to make an offer. Look into the reason they are selling. If it is something like the owner got transfered to another state for work, then they want to sell reasonably fast so as to not have two payments. If it is the case that they are moving around the corner, then you want to look into possible problems that could run into the thousands and they are trying to unload it.
Do your homework. If you really want it, find out about the septic and whether or not you can hook into city sewer. If not,l then you would be stuck with a hell of a bill if anything goes wrong.
Now if you could hook into the city as far as utilities, and you really like the place and want it, lowball them out of the starting gate. I'd start out at $50g's and see how upset they are and see if they counter. Then the games begin. Your realtor should be able to dig up the facts about it and relay the facts back to you.
Whatever happens and whatever you find out, please keep us informed. I'm sure I'm not the only one curious as to how everything shakes out. Even if you do lowball then and they would accept and you back out, it's a lot of info for the next person. It is a unique looking place though.
One other thing to consider, and it just came to me....a good friend of mine bought a one room schoolhouse when he was in out town. The building has a large two car garage added on and it had been remodeled inside. There was a kitchen, bathroom, dining area, living room, and a utility room down. The upstairs was an open loft for an office, a full bath, and a master suite. The house was heated with propane and electric. The propane bill for all winter was less than $100. That was for the complete winter. They had electric baseboard heat for when it got real cold and their electric was never more than $100/mo. The walls on that old schoolhouse were one foot thick. When the sun was out it would warm the bricks then radiate it out over a 24 hour period. One of the most comfortable homes that I have ever been in
