Financially speaking, unless it’s a superfund site which requires millions of dollars to remediate (or similar) it’s always more advantageous to own something than not to have it. So compare your situation to someone with similar earnings and assets except you own a percentage of a piece of property and they don’t. Clearly, you are better off.
Presumably you could sell your portion to one of the other heirs, no? Borrow against your equity in the property? It doesn’t need to be immediately liquid to have value.
