I would be inclined to tell my wife to make the decision, it is her family...
Good golly, I'm looking for your hidden microphone! That's almost exactly what I did. What is surprising me is that the little lady who has always let her big brother run all over her has sprouted a spine. Well, maybe that doesn't sound right. I would be wrong to infer my wife is spineless. Just when it comes to family, she generally gives in and they know that fact. They've used that against her all her life. Now that she sees exactly how dirty her brother is willing to treat her, her attitude seems to have changed. Her last comment this afternoon was "Let's go ahead and buy it next week. When and if her brother comes up with enough money to get our attention, we'll agree to listen to what he has to offer; no promises.
Being the cynical type, I'm relatively certain that her brother has a buyer on the hook who is willing to pay him a handsome profit right away. Knowing that is a very real possibility, I have to agree with my wife's take on the matter. Go ahead and buy it. Just start clearing out some of the assorted out buildings that housed goats, cows, chickens, etc. and clean up the outside in general for the first month. If her brother hasn't come up with a cash offer by the time we've finished cleaning up the outside, make the decision at that time whether to fix it to rent or just tear it down. The two contractors and the one building inspector told me that it is worth saving. Also, if any of my kids decide to go to college here in town, it would make for a great place for them to 'rent' with some roommates. There again, maybe I'll already have it rented by then. One of the contractors has a long time employee who is going through a divorce and has asked to speak with me about a reduced rent amount if he works off the missing part of the rent by renovating the home. Normally I'd be extremely apprehensive about a deal like that, but this is the renter who found the sagging floor and this is an employee who has worked for him continuously for the last 9 years. My friend, his employer, seems to think his employee would hold up his end of the bargain.
I can't recall if I've mentioned it before, but I'm relatively certain it needs a new septic tank and field bed. Clearly I have plenty room. Would a 1000 gallon tank be a normal sized tank? I put in a 'huge' 2000 gallon tank when I built my home, but I have a total (including half baths) of 8 toilets feeding that tank and field bed. This older farmhouse only has one bath. I haven't even started pricing them, but I'm wondering if a 500 gallon tank would be sufficient. This part is where I asked in another thread about purchasing a compact excavator. As long as I have it inspected at the appropriate times during construction, my contractor friend would sign off on doing the job and mostly just supervise me as a trade off for giving him a year old computer system out of my office.
