Is tax liens a way to purchase a house with out alot of money and bruised credit?

Answer 1

Purchasing a tax interest in a property (IE buying a property at a tax auction) is just that. You're buying the taxes on the property.
And you'll probably get a tax deed recorded, and you'll have vesting along with the current owner of the property.

In order to obtain sole title to the property you may have to take the current owners to court and sue.

I would read up on this in your home state, different states have different practices.

Answer 2

Only way I found is to try getting an FHA loan. Ask your local bank about that.
