Check local law, whether you have to accept varies by state.

And no, the purchaser would not have a viable claim over the incorrect record as all information concerning the subject property must be independently verified.Owner should have accepted the pre-auction offer which turned out to be ~2x the high bid.

When I have a situation like this, I give them a written notice to accept the property in its current condition or get out.

That being said, while the intent is that most investors in a 506(b) offering are accredited, the sponsor can accept up to 35 "sophisticated" investors into the offering and still be within the rules.All told, private offerings are 100% a buyer beware investment.  

So now I am 25 and I was finally presented with an opportunity (duplexes are super rare in my area/state btw) I put an offer in and it's looking like it's gonna be accepted!!

Accept it "as is" and fulfill the lease.By responding quickly, professionally, and confidently, they realize I am not an easy target and choose to move on.

CAPs are an individual investor's measure of acceptable risk for a given reward.

Down payment should be about the same (20% on a buy-and-hold) but you'll see an additional $3-$6k on average in CC and the ability to keep it off of your DTI/Personal credit along with hopefully no more hard inquiries on your credit (many lenders will accept/perform a soft pull).

When I read the bank would accept 91k I understood that to mean that was the 30 day payoff amount on the mortgage.  

I am not sure there would be enough margin in this to support your goal.We know people are not lining up to accept section 8 so you could build housing targeting that group in some locations.
