Nuts for the stand have come loose over the years.

And I also find it ill advised to potentially lose earnest money and definitely loose Due Diligence money on a deal I have zero idea how to close.Any other questions?

But as @Etienne Martel said loosing $1800 is better than $10,000.Walk away from this deal.

Duplex 2-4 unit Advantages - better cash flow, less stress for the owner, one tenant can pay the payment while you turn the other unit, gives more income streams, if you own 2 duplexes that is 4 units, if you own two SFR it’s 2 units, if one is vacant and you loose half your income.

Have him hand over keys and release you and you cut him loose.
