I recently met with the owner of a property management company.

3.Any tips for managing cash flow and leveraging existing assets to keep growing my portfolio?

Does STR self management make sense (from a tax offset for W2 income) without accelerated depreciation? 

However, it was taken from one of his seminars so it is nice to have a live recording of him talking about it and such.Go to ronsgoldclub.com and you get a free 30 day trial along with his wholesale course....and anything else you can manage to download in 30 days.

@Adam SchneiderRecommend 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, 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.

That said, we do lending out of our SDIRA and there are some considerations about prohibited transactions and set up (checkbook control or custodian managed, for example) etc. that should be reviewed with a custodian or SDIRA expert.

Who can provide a referral or insight on managing this rental?

We use QB for accounting and Rent Manager for PM (I often feel like it uses us - although there customer service reps are great).

For a section 8 fund also ask about there experience in owning and managing section 8 housing as if it is not very hands on, it will not end well.

I would really recommend you hire a property manager.
