I would also like to know any relevant information as it regards to fees and procedures.

I have saved around $13,000 (I would be willing to part with probably $10,000 as a down payment leaving the rest for emergencies.) 

@Warner BellOthers can answer the technical-procedure questions for you, but I am curious as to your "subject to & buy and hold" clause.

I also have some cash put aside for emergency.

In terms of assets and liabilities I have no debt and paid off mortgage, $25k in emergency fund and decent IRA.  

Thought is to pay it to zero and then put a line of credit against it for emergency/killler deal funding cash.  

The first step is always the scariest, but as long as you're patient and sock away money for emergencies, you'll be just fine.  

Services includes: " marketing rentals, lease structure, collecting the rent, and being on call 24/7 for rental emergencies."

Is crowdfunding one of the newer emerging concepts?

You would think it would be standard procedure for any management company when they send out their maintenance guy for any reason to take 5 minutes and inspect the filters while there, at least just to report if tenant is not doing it, but we haven't found that to be the case.
