@Miho Y. if you have a $1500 water bill that is not the fault of a washer/ dryer, even $500 is crazy if that is per month, I'd start looking for leaks.

Items such as controlling the flooring on the inside of the unit (premise is noise abatement so some associations do not allow LVP), limiting rentals all together (premise owners take better care of the units), limiting certain bathtubs (premise: Common water heater and large jetted tubs use more water), limiting STRs (premise: they do not want strangers having unabated access), no washer/dryer in unit (premise they may leak resulting in damage to other units), etc. 

@Jennifer S. if you are living in CA you can refi with institutional lenders as looks like you were quoted a lite doc option.

The Duplex we have under contract had a roof leak during showings and the current owners insurance took care of a new roof and fixed the inside.  

Purchase price: $595,000 This was a cash-out refinance from a property that I purchased (with my partner) in 2005 (initial purchase price was $546K with only $5K down, the pre-bubble no doc good ole days).

Do you have something in the purchase paperwork or docs that specifies HOA fees? 

Not much doc prep needed if you use the AirBnb platform.  

During inspection period the other buyer discovered a gas leak and backed out.

What does the disclosure doc say?
