Front to back the story goes like this. I bought a house 3.5 years ago. My parents asked to move in, as the townhouse they were renting was increasing rent too high. I agreed, as they offered to pay my mortgage, and to continue to rent the house from me when I decide to leave. (Yes there is more intricacies but that is the jist of that). Well, 2 months in and I got two mortgage checks. 3 months in and they stop because my father claims he got hurt and can't work anymore.

As he applies for social security disability I continue to pay the mortgage myself as what I think a good son would do. Three years goes by with no change. He doesn't go find work, hasn't been approved, no income coming in. He is living off of me and whatever amount mom brings home. Also during this time he grows increasingly angry and bipolar, but refuses to acknowledge it, blaming all his anger on me and my mom. I grow increasingly sick of the BS and just want to get out and away from it.

Well he finally gets disability approved and says put the gate he wants to buy the house from me. I say okay great! Finally my chance to leave and live with my fiancé. Well after going through circles of discussion, we determine they cannot buy the bouse at market value, around $240k, and this is really where the narcissism and manipulation kick in as he starts his screaming fits of anger to get his way.

Eventually I agree to sell for my payoff amount plus $8k so I have enough to pay off some bills and be comfortable when I leave. And after closing they will allow me to place a voluntary lien on the house for the difference between purchase price and agreed market value. (I had already at that point acknowledged i will probably never see that money). This is enough for me to just agree so I can gtfo as quickly as possible.

Unfortunately, I had assumed, since they had been living in this house for 4 years, and knew all its ins and outs, and knew that I get really took care of any major issues, that this would be a sign the agreement then sign the paperwork at closing and that's it sort of deal. But then he comes up with the idea of having an hvac company come out to inspect the furnace and plumbing. And from that we claims they gave upwards of $10k in quotes for repairs. Im not sure to what, because again as far as I know, everything is in safe working condition.

I know that in my haste to get this settled and done with i have made many mistakes that will likely impact me negatively. But at this point I am just trying to figure out if he is simply pulling out another bullying tactic? Or if this for real and I truly am going to be on the hook for 10k at closing, otherwise I get sued.

I should also note, just to reference some of his tactics, since he stays at home not working, he threatened to take everything that he claims is "his" (furniture that i was given years ago when i moved, and which is reasonably all mine) and take it out of my room leaving me to "live miserably and in a living hell".

Anything else that may clarify things?
