Had the dealer go up with me on Sunday. He agreed that the home had not been well cared for and that it didn't look like they knew what they were doing. He indicated that most of the leaking was from the joint between the real logs (only going up 8 ft) and the log siding that continued up to the roof line. The outside logs hadn't been cleaned, stained, and sealed in many years. He felt things could be fixed without too much cost/effort and actually was interested in buying the place. He said he would be glad to help out in any way if I purchased the property. I Used 3+ hours of his time and all it cost was lunch.
Anyway, I had made a low offer on Saturday and after speaking with the dealer was ready for the sellers counter offer (I would go up a little). The counter was too high, but it was as low as they could go with out losing money on the deal. I could have come back to see if they would take a loss, but in the meantime (actually just today!), I found a beautiful 110 acres (closer to what I wanted in acres) just two miles from the log home. It was an excellent deal and I just signed the contracts a few hours ago.
Oh well, learned a lot about log homes, and I'll probably build one on the other place in a few years.
Thanks everyone for the help on this!
