The gist.

We live on her parents property. They live on 12 acres. When we were looking for land to put our manufactured home on, he offered. Or i should say, begged us to move out here. Pretty much said we could do anything we wanted. Treat the land like its our own. He just wanted his little parcel to mess around on and didnt care what we did with the rest.

Turns out he definitely cared.

The only stipulation was that we couldnt get a loan and tie in the land. He wanted to keep it in his name and didnt want to risk losing it if I lost my job or whatever. After a LOT of debate I relented and we moved out here at the end of 2020 (brand new 2020 manufacturered double wide home). He cut out an acre to have rezoned to residential (but still in his name). However the home does not have its wheels or anything anymore. It sits on bricks. This was required by the county even with it being on a chattel loan.

Fast forward to now. Hes now refusing to let us do anything, and is growing increasingly toxic and unstable. Basically we need to leave and we have a strong suspicion that is his intent for reasons I wont go into. I know it wont be much longer until he forces the issue, and hes making things extremely miserable. Hes made mention of kicking us off the property because its "his land". Idk the logistics of that or the legality but I have no interest in fighting to stay.

My question is, what are my best options?

Land around here has skyrocketed the last few years. We need at least 2 acres (we are very rural and do a lot of homesteading) which is running 12-15k an acre even in rural areas unless youre buying 15+ acres. Im just trying to figure out the best way to go about it.

Im aware of the costs associated with moving the house (moving, septic, well, etc) which is another concern.

We are looking to do this in the next 12 months or so. I hope we can hold out that long. By that time we should have the credit cards and small loans paid off and another 5-6k saved hopefully.

Im just not sure the best way to go about doing this. Is there refinance options? Am I stuck with the chattel? Can I do a withdrawal against my 401k? USDA loans? I honestly dont know what my options are as I assumed this land was going to be my wife's inheritance. Hes now gone off the deep end and we are 99% certain hes going to lose the land in the next 5 years. If not sooner.

Any advice appreciated because im a little overwhelmed right now trying to figure this out. Though emotions are also running high so that doesnt help.

Honestly if I could just sell the damn thing for what we owe on it and get out of it I would love to do that too and just start over and find us a stick built home instead. But I assume that would be a huge deal with it not having its wheels anymore?
