No hot water, stove not working, no heat, broken windows, door locks not working, loose railing, no lighting in common areas, garbage not in dumpster, no smoke/co2 detectors, etc. anyway that has been our experience. 

Common sense and common math is the name of this game

I hope you have a big fat deposit.

Reset your personal goal from the fat double-end commission to not getting sued by either party.

It's two floors with the bedrooms upstairs and common areas downstairs (ie. kitchen, powder room, living room,etc..).

From what I’ve researched, blanket loans are fairly common, but I don’t know if the fact that one of the properties being refinanced instead of purchased makes a difference.

This is a common scenario where buyers ultimately are not approved for their mortgage. 2) Home Inspection Issues 3) Home Doesn't Appraise 4) Buyer Can't Sell His or Her Home 5) Liens or Title Issues. etc ...All lenders are VOE before closing, the new mortgage scenario we all must accommodate as of today as a lender I know this was not the norm 4 weeks ago, but now I do. 

Also I have common areas cleaned weekly now should that be sufficient as far as "my part goes" or should I have them cleaned more now?

Study up on what the common scams are that people might employ against you and be on guard for these. 

People still want to buy. 92% of new listings last week went under contract, bidding wars still common here.
