This depends on so many things, so it will be tough to give advice without knowing your situation or anything about the house.
If the house is worth more than the back taxes and the repairs and you have the money, pay the taxes, fix the house up and sell it or rent it out.
If you don't have the money, sell it to an investor. You can use that seed money to hopefully get going on a house that's in more rent ready condition.
If you need the cash for the repairs and taxes maybe get a Temp Job from a Temp Place.
There are 7 days in the week you could work towards this and getting the place in rent ready shape for only a few thousand dollars worth of spare time work is a GREAT opportunity to get a monthly rent check coming in with no mortgage.
