I would have a leg up in that I am a professional photographer, and that my rental would have a large fenced yard, playset,and a playroom. 3 rooms with 4-5 beds.I did reach out to property managers and it seems i was undervaluing its revenue as an LTR.

Pretty rare from what I see that cities allow or want this....turns single family neighborhood into multi family and most of the zoning people don't like this.Plenty of issues from their point of few of why they don't like it.....parking is one...now no one parking in garage, and potential for more cars...so now 3-4-5 cars in the street.More taxing on the water/sewer/trash/police/fire/city services.I wish you the best of luck with this. 

There is a seller that needs to sell his rental property quickly (within ~45 days) as part of a divorce agreement.

You are happy to take charge, but they need to pay 50%.Can the split be like 45:55 for I pay 45% of the cost and my neighbor pays 55% of the cost because it's their dog that is lunging towards the fence when it barks and therefore reducing the fence's longevity?

I can even charge a $45 pet fee and add it to the cleaning bill.

You may want to check out the Detroit market as we beat Miami for highest appreciation last year, and the US Census Bureau finally recognized that Detroit's population is growing (they're about 4-5 years behind on that!).

I do not have a firm grip as to what the % is but I have had 3 accepted in this manner in the last 45 days

That will get you an additional 45 days (a lifetime in a transitional market in an election year) to identify that elusive replacement property. 

It seems like that they do not want to pay for the 45 dollars to go through it.
