Rent new house, move back to old house, or sell old house?

We have a 3+k sq foot home thats been paid off. About 15 yo. my husband wants to sell this house and use the money to invest. Reason is, he’s getting laid off soon. I recently got a FT job but it’s a little over half his salary. After much debate we found a smaller home and purchased it. I agreed to buy if we pay off this smaller home with the money Rhe buying process was bad. My guy instincts and questions weren’t answered. But I moved forward w it. We discovered the owner knew about a leak and didn’t let us know. She covered rhe area w boxes etc. in hindsight I wanted to leave the purchase. We spent over 11k fixing the leak. He now won’t pay off rhe smaller home. I am refusing to sell the old house and wanting to go back to it and rent out this new one and wait for rhe market to improve to sell it. What would you do next? BTW, we have about 50k in savings. Please don’t tell me I shouldn’t have bought the new house in the first place. … I know I should have been stronger.

Bottom line is: he was not honest and transparent with me during the time of the purchase/. I felt manipulated with this whole process of house buying.
