In general residential PM unless a full service company the brokers and agents tend to do it on the side out of necessity for another residual income stream.Some think of it this way.

Personally, I would create an amortization table and figure out at what interest rates and amortization periods you can handle the debt service.

Does anyone have any suggestions for a property manager or company that could provide services for a temporary/interim period of time?   

Utilities are generally public and you can call them to get averages, taxes are public as well and can be pulled either from a assessor website or at their office, insurance companies can give you cash value and replacement value quotes by giving them an address, general rule for running calculations for vacancy is 5-10% of gross income, I have seen maintenance expenses all over the map (anywhere from $300-750 or a % of the rent - those vary depending on the number of doors in the deal as well as how much deferred maintenance has to be dealt with or how much rehab you are going to do to negate the deferred maintenance), contracted services, call a few landscapers and get quotes and use those for your analysis. 

If you are currently using a skip tracing service please comment which one and how your experience has been with it!

There's a 25 dollar background check which goes to the service which runs the check.  

Then take debt service out of the NOI. 

A rehab should reduce your operating cost and offer the opportunity at higher rent, but it probably won't show up in the bottom line numbers until year 2-3.Same goes for replacement of major systems with a long service life.

Today I got notification from Gas Company that the service on the property has been shut off 2 days ago per tenant’s request and it’s now under my account because I have a continuous agreement as owner.

He's focused strictly on services for entrepreneurs.
