Less inclination to sell so less inventory on the market yet and less people overpaying to find a home for 1031 money... maybe a wash?

Either way, like Roy mentioned you should be able to power wash or blast it off.  

In fact, you can offer a discount for an agreement that is secured by a solvent co-signer.  

I had a very similar situation recently (ironically on a 1008 sqft 3/1), and when I ran the numbers it was a wash (on a flip).The delays caused by designing, permitting, and inspecting the second bath would have increased my rehab and holding costs, and delayed other parts of the rehab, to the point that it didn't make sense to add the second bath. 

(Yes, we planned to power wash them.)There were ten down units  (Yes, the lender already knew that from our documents; we were getting $100,000 back from the seller in the deal to repair them and our contractor estimates were for $60,000 to do the work; that was the value-add in the deal!)

Was he advised that there would be a pet in the home.. prior... it is simply he's allergic to cats????

Yes, less profit but it's far more important now for me to stay solvent.

He wasn't directly targeting his clientele was he?

If the clothes dryer is electric (like ours), the tenant might be washing/drying clothes almost everyday. 

I'm thinking of smaller handyman type jobs like changing a switch, replacing hoses on a washing machine etc.Is there any potential for liability if something goes wrong and a non licensed person did the work?
