Buying house after HOA foreclosure

[Mike Landry]

I have contacted a Real Estate Attorney but would like to get some thoughts from you guys here.  Here is the deal.

The person I am talking to owned a house free and clear. They never paid the HOA or the taxes. In november the HOA foreclosed (texas). An individual was the winning bidder and they also paid the back taxes to prevent a tax foreclosure. They were given a constables deed to the property and the original owner has about 60 days left to pay them back and redeem the property. They owe them around $40,000.

For all you deal experts, how do I buy this house?  They don't have title until they pay the redemption.  And they can't redeem it until I buy it.  I can't loan them the $40k secured by the house because its not in their name.  And I don't think redemption rights are transferable.

Has anyone dealt with something like this? The people that are owed the $40k are "not being nice" and are trying to force them out of the house or pay rent. ARV $200,000.
