In my experience with residential, the more work that is needed beyond cosmetic the lower the profit at the end, which when coupled with the time required, ends up being a much worse hourly return on your time and money.With the added difficulty of the heirs not being in communication with each other and the rest of the hair on the deal, I would move on.When you first get started, I think most people don't respect the value of their time enough and haven't seen how high a percentage of deals apart. 

Additionally now one of the other tenants is complaining about a skin condition that she believes is developing from the cat (showed us a picture of a rash appearing on her face)I guess my question is, do we have any course of action here in terms of removing the pet.

Hi Mario,I know at Neu for a while they had so many leads that they were having difficulty keeping up with the demand. 

I want to see skin in the game from the buyer.

Not looking from the legal aspect but to see if any of these people have more skin in the game than just a  renter... 

Network with some colleagues there and see who they are using.If you are still having difficulty finding someone local - you may want to look for an accountant remotely.

You may also have difficulty getting a bank to finance anything if there is even a hint of a second.

In posting this, I hope to gain some insight into some of the difficulties and challenges experience real estate investors face on a day-to-day basis.

I am in the Portland, OR market and finding deals here that pencil out is extremely difficult.   

In general read these two links pretty much true for any market.https://www.biggerpockets.com/forums/311/topics/227602-difficulty-selling-rental-properties-at-loan-amounthttps://www.biggerpockets.com/forums/52/topics/402737-is-pm-responsible-for-bursting-pipes?
