Well everyone...
Thanks for all the help and advice. You are all wonderful.
Unfortunately, we're going to have to try to walk away from this particular house. The sellers are just doing too much creepy shit- i.e. doing minor repairs or having services done to the property and insisting that we pay for it. This is all stuff that is above and beyond our accepted offer, and the property was being sold AS-IS. None of this is new, they've done other stuff that was sending up red flags. About a week ago I made a stand and I was firm with them (they didn't want to allow an inspection until AFTER we made an offer). They settled down and quit trying to do creepy stuff for about a week. The very day that we offered and they accepted, they started back up again. We've decided that we don't want to deal with these people anymore (they were also going to finance us).
Hopefully their actions have now rendered our signed and accepted offer null and void and we can cut and run 100% free and clear. We haven't closed on the house yet, but there are a few instances where we might be completely SOL and have now "bought the farm", whether we like it or lump it. We're going to pull an attorney out of the yellow pages first part of next week and run all this by him/her to see where we stand under the circumstances and within the laws of our county/state.
So thanks again for all the advice... I just might need it to maintain an investment i'm stuck with.
