We have a 1970s mobile home given to us by my husband's mother. It is a nice home, the only problem is, it has so many problems and we have no money to fix them. The major issue is the sinking floors. We think it originated from an a/c unit that wasn't properly draining, as well as a closed off vent in the back bedroom. The floor is sinking in almost every room of the house, including a big spot in front of the window the bad a/c was in that extends to the middle of the floor which is the kitchen, as well as a soft spot in front of the fridge, a small sinking spot in our bedroom doorway, a small soft spot under our bed, in front of the toilet and the floor in the unused middle bedroom is sinking in as well. The floor is so uneven that when you put a ball on the floor it rolls as the floor is curved in and uneven due to the sinking floor. Honestly, if we could afford to we'd just move out as I think all the repairs would be more than the worth of the mobile home at this point. The only good thing I see about this is that my husband is able to make the repairs, we just literally cannot afford to save any money for it. Other issues include soft spots in the wall where the a/c was and what appears to be mold when you peel back the paint on the walls where any a/c unit is. There is also a leak in the roof that we keep having to patch. We are still using a/cs, but they are not contributing to the sinking floors anymore I don't think. For some reason, the floor keeps sinking more and more, could I literally fall through? Could the whole home just cave in on me one day as I'm sitting here? I am scared that I or someone else will fall through the floor one day, so I avoid walking on the soft spots. Any advice to make repairs as cheaply as possible, as well as how to go about fixing the floors, would be greatly appreciated.
