Some of the things I have done in the past in similar situations –
1) I have paid cash for the house, moved into it (no matter how much work it needs), since it is far from my house, and rented out the house I was living in before. Now I can orchestrate the work that needs to be done, sell the furnishings and the car, and when the house is rehabbed, I would either sell it or rent it.
2) I called a contractor who is a financial friend and offered him a stake in the profit in exchange for the work.
3). Do the foundation work, re-fi the house to get my cash back, and finish the rehab, again for rental or for sale.
