You would need to track down the homeowner and cure the foreclosure.

I'd post an appropriate Cure or Quit notice to change the locks back or give you a key.You can also post a Notice of Inspection (or Repair) or for whatever other reason you need to enter the home. 

The proper way to treat any unpermitted area is to make a cost to cure adjustment which brings down the value.

That can limit profits.So how do you cure that? 

TinGet your cash sources, whether it be banks, hard money, private lender IRA loans, etc, 10% plus down in escrow, contingencies only inspection by certified prop inspector, do a final walk thru before you release funds Don't cure notes, pay them offDon't do sub2 or wraps on NODsAll the seller needs to do is get a lawyer to try to get out of contract Then the AG gets involvedDon't say you are foreclosure counselorsIn short pay all cash for a vacant house for NODs

it appears there is already legislation proposed to cure the problem.TYLER v.

A 1970's cure was to dig out around all the basement walls coat them with a 1.5 inch layer of tar to seal it up.

Not trying to be crazy about this but a lot can go wrong and a sheet of paper won't cure everything.

You can't really cure it.  

Now, that may well mean that the investor has to come up with cash to pay on the deal giving the seller enough to pay his expenses.The really bad thing about forums is that I have clowns to the left of me and jokers to the right, and here I am having to post, spending time and effort correcting them so that the unknowing don't get in trouble or get their heads screwed up.No, you can not just do a quit claim deed and cure the fact that title was passed in violation of the deed of trust.
