I would assume so, but it's best to check with the lender to see how they interpret official FHA guidelines which read:"Net Self-Sufficiency Rental Income is calculated by using the Appraiser’s estimate of fair market rent from all units, including the unit the Borrower chooses for occupancy, and subtracting the greater of the Appraiser’s estimate for vacancies and maintenance, or 25 percent of the fair market rent."

I self managed the property though I also had people in it that I knew pretty well and I made sure to have some other trusted agents in the area that could check on things for me when I was out to sea. 

A couple of great books on I'd recommend checking out on the topics of Acquisition using OPM and Creative Financing are below.The Book on Investing In Real Estate with No (and Low) Money Down - Audio BookWealth Without Cash - Audio BookHope these help you as much as they've helped me!

We found great tenants on Zillow, background checks from Avail.co were inexpensive and easy (you make the applicant pay for it).

Our current tenant moves out at the end of the month and we just visited the property to check out the condition for showing it to prospective renters.

I.e. a prospect has a background check that under the owner's screening criteria says it may require an additional deposit, the owner must communicate with that prospect regarding that you may not do so.   

Additionally, it might be worthwhile to check with your local housing authority or building department for specific regulations and standards for rental properties in your area.

I wanted to check if this is something I can hire someone else independently but then I worry that current plumber wont guarantee their service.

I have been on so many claims in Texas/Louisiana recently that folks end up getting a $1200 check for a $15000 roof!
