Remember when choosing a property management company or any other contracting service for that matter, CHEAPER is not always (and usually NOT) the best.  

My company (Holton-Wise) for example sell offers a turnkeyesq service where we broker deal & then do everything you mentioned above in house.

Anyone who works for a financial institution can be a certified mortgage professional, which means they never got training in mortgages, and don't even know when they are breaking laws. 

Anybody have any thoughts on paying for cable vs. netflix (or other streaming service) in an Airbnb?

Also, if I do invest in these areas, I'd like recommendations for property managers, handyman services, and other professional references.Thanks.

May I also recommend that you suggest the services of an appraiser for your buyers before they make an offer on a home instead of suggesting they wait for the bank appraisal to screw them over!

To build trust I would like to VOLUNTEER my time and services to someone who could use the help.

There is no such thing as being a broker in DC without obtaining a broker license.The code provision you cite exempts certain people from needing to obtain a license, even though they appear to be providing what may be considered brokerage services under DC law.

Going off that train of thought I could also use the county auditor site and do the same search.

I've had some commercial lenders also look at my global debt service coverage ratio, but they don't reduce the income by 25% so my numbers are much better when a commercial underwriter is evaluating me than for a conventional loan.
