@Gerald Evans,When looking for a tax professional with the expertise in REI the proximity would be of secondary importance.

Furthermore, businesses have an interest in keeping the space well maintained and professional at all time.Therefore, businesses will not trash your office building like people trash your apartments. 

Who would be the best professional to go to for paid advice?

Do some some due diligence, search and read previous discussions, select few professionals and then speak with them, then narrow down to the one you wish to work with.

And that means your investment becomes more valuable over time.BiggerPockets (of course) is an invaluable resource in connecting to local investors and professionals, who can tell you a lot more about the market (local blogs, Cromford type reports, etc.).You'd be amazed what you can learn by reading the local news.

's situation, it would be best to find a professional to handle your handyman and lawn care work.

Their involvement will mean the bottom line of what they get from the profit according to a professional appraisal after the repair/rehab or a resale to someone else. 

That's why such people called "professional Tenants"

Did you hire an engineer/professional to look at this and give you recommendations or did you go straight to a foundation company?

This will keep you organized, and professional in the eyes of your tenant(s).
