Here's a Typical Story
Mark inherits a property, but he lives out of town and has no idea how to manage it or cash it out before the tax sale. The property needs repair. Taxes need to be paid.
Mark doesn't have the time or the money. So, he decides to just let it go to auction and be done with it.
You come in and offer him a couple hundred dollars in exchange for signing the deed over to you. You then resell for a tidy profit to a rehabber or landlord who is happy to do the repairs. Everybody wins!
