I also have been volunteering with a flooring company, a drywall person, and a house flipper who did the majority of the work himself to learn all of this. 

It does nothing but efficiently charge me a monthly fee of 29 dollars for NOTHING, as it only served to send random letters to the bureaus on my behalf that all got rejected because they were poorly written and devoid of proper identifying information to carry out the request which by the way, was pointless because it only sought to keep organizations from pre-approving me by denying them access to my credit report.

A repair allowance is one possibility, so don't volunteer to the next lender that the place is rent ready. 

Talk to a person, get their email, and send info only after verifying the person/organization really exists.

Maybe for tying the sport organization back to the market, maybe to have a good excuse to visit and see a game!

I'm sure in the meantime, you could let them know you will be doing some landscaping which involves using an organic fertilizer in the garden.

I looked up and I don’t see them as a part of a professional Managment organization like NARPM.

However, I'm a major volunteer of Information Technology professional services to a local non-profit Christian school for the last 13 years.

Other than the usual camaraderie that exists when you are active in any organization, there isn't much difference from my perspective, however it is a fair amount cheaper on an annual basis for a Non-Realtor. 

Some of the work has been done organically as my family has grown but I am looking to take an objective look and finish the project off so I can move to the next one.
