The main house is ready for rent, while I'm still working on getting the ADU ready. 

When applying for new loans at least from my experience its never been an issue with any of our clients getting a Heloc on primary then converting that primary into a rental. 

Any pointers as to where I can get some benchmark answers for these questions?

If we are interested, we will get in touch with you.

@Ivan WudexiRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

I am currently 21 years old, and have recently begun to get into what it would look like to invest in real estate.

If you invite the government into your business, you get the good and the bad.2) In my experience,(and I may get some hate mail for this) the average section 8 resident is harder on the property. 

I'd message the sponsor and tell them you'll be traveling to the area and it'd be nice to get a brief tour to see progress.

Easy to get someone on the phone, which is a big one for me and something I am willing to pay a reasonable premium for.
