Should I sell my rental property or keep it if it has mold growth problems?
I'm going to assume that you will spend the money to fix the mold problem correctly.  Using your numbers, after that is done, the home is worth perhaps $280k. To evaluate whether or not to sell, the amount you have spent on the house is irrelevant. The only thing you need to ask yourself is this: Would I spend $280k to buy this house today? You might, if you were happy with the rental income that you were getting. If the house is fully rented, it earns you $24k/year, which is an 8.6% return if you had purchased the house today at $280k. Of course, you will have vacancies, taxes, and other expenses bringing that return number down. Figure out what that is, and see if you are happy with the return based on those numbers.  If you decide it would be a bad investment for you at $280k, then sell the house.  By the way, this question works for any investment, not just real estate. When deciding whether or not to sell stock, the same thing applies. It is irrelevant what your cost basis is. You only need to ask yourself if the stock would be a good buy for you at the current price.
