Most likely you will have to get another loan or try to do some of the work yourself. Better yet leave the renovations that can wait and only work on the things that may effect your living situation.
If you bring in a partner that person will most likely want their money back quickly. That means you'll have to refinance the house and if your home is already at the top of the market with all the money you put into it , then you will not have any equity.
Make smart decisions and don't let the house take over your life. Good luck.
