Yes, they should be happy to do it and yes, you'll have to find alternative solutions for the buy and rehab.

I now have a solution for closing these deals without needing a more experienced partner.

However, your property manager should be able to guide you on legal options and solutions to secure the property and possibly help with claims for damages.

Even if the area is cleaned up, I wouldn't purchase any rental real estate in Kensington, Fishtown or Northern Liberties for a few years.

I also recommend including some move-out instructions for cleaning, how to turn in keys, when they will get the deposit back, etc. 

I would use cleaning services but it's my understanding I could use more than one company over the course of the year to limit how many hours one company spends on it.I'm looking into a utilitarian STR more for business travelers, so this won't be one where everything is perfect, it's bound to accumulate wear and tear I think.The STR would be out of state, but I plan to travel there for probably two weeks a year where I would perform many repairs myself.

In accordance with the lease agreement, the property shall be fully vacated, cleaned, and returned in the same show quality condition upon move-in.

Fast solutions have slow problems, tie yourself up in getting cute and the reward is you get a property and risk is you lose it all.

The other things to keep in mind utilities, cleaning before/after (fee, does it need to be dictated?)

Perhaps one level is just to clean up the unit and install new appliances.
