The same day they moved out, my property manager e-mailed me pictures of the now-vacant property, and said the bid for any "Make-Ready" items (paint, cleaning, yard, etc), would be coming soon.  

It is totally possible to manage booking/payment/access yourself and contract out the cleaning and maintenance.

In the end their investors will move on to the next thing the oracle talks about and you should be ready to clean up Wall Street's mess...again.

Maybe an electrical update.

Maybe our PM have bigger projects, maybe some of the investors want him and his team to do renovation so it is a bigger business for him, or maybe this is just the regular procedure, it is our first property and basically we are still learning about all of this, but the facts are that we are paying for the mortgage, electricity,water, somebody needs to cut the grass especially in this period of the year ( we don't even know is the grass cut or not) and so on.So I was trying to find out what is the normal period in which the professional PM is going to find tenants and rent the property?

There needs to be good light where cooking and food prep occurs.It is costly to add plumbing and electricity later, so placing such in the right places from the start, in anticipation of future needs, is a good idea.

What's even more crazy is that it was over a $58 electric bill.

If there is not separate electricity, I'd definitely factor in the cost of splitting that for whatever units don't have it, which may be somewhat high.

My contractor was cleaning out a property today, and I get back from the store where I was buying garbage bags for him to use. 

Assuming it is clean have the Seller sign a deed to you.
