Apparently my guy used the wrong gauge wiring, junctioned off existing circuits for the GFI's & so now the backsplash needs to be torn out Other circuits were incorrect as were the lack of AFCI's & he had double tapped breakers.

Other than that, have your electrician make a homerun new circuit to the desired location. 

Here are my responses with deal breakers in bold:Install gutters - If there are no gutters at all? 

A solution I have used in the past is to make sure all knob and tube wiring is on a 15 Amp breaker.

@Sarah Byun You do have to remove them from the tenants circuit unless you compensate for them.

Although these $685 is nowhere near a deal breaker, it’s a small reminder to make sure that you are taking everything into account.

Some people do double close regularly but in general you hear wholesalers close only if a) they have to since the contract is not assignable, mostly REOs and Short Sales or b) they did such a good job that the fee they will be making is especially large and they don't want any issues with the buyer or seller getting POed if they see how much money they made.If they put the contract on it because they in fact think it is a good deal that they can easily sell then putting up a deposit should not be a deal breaker for them.  

I am from the midwest, wondering what people main concern / #'s that they look for when they do a rental calculator and what #/% they are trying to hit - basically what is your deal breaker.

Could this be a deal breaker? 

Secondly if the knob and tube is in good condition and isnt over fused or the  breakers are the proper size then its not a bad thing.
