Many investors with purchase or refi into the DSCR loans to "free up slots" with Fannie/Freddie loans so they can continue to get the benefit of low down payment properties when house hacking. 

He sounds like a young version of me: I own a rental RE business, work a traditional full-time W2, teach adjunct university on the side, do some of the rehab work on my new units myself, and still find slots for family (wife, adult kids, siblings, parents), dog, playing in a professional band, and other stuff.

I can't afford liability insurance because my cash flow is razor thin.

I try to group say 4 or 5 tenants together for 1 time slot with the expectation of a bunch of no shows.

We plan on continuing to purchase properties in our individual names until we max out our available slots. 

Your margins will be razor thin even if it only needs paint and carpet.Ways to buy a BRRR in my order of preference: HELOC/LOC, private lender, bank loan, my cash, hard money lender.

If so, this might be a way to free up your FHA slot.

Leave an American flag on the front flag slot or install one with two screws.

I am a shark in the negotiation chair, and the example above is a simple examination of that.If you hire a agent to defend your interests, then by all means... go right ahead and direct them to get you the most possible.  

Also there are companies who run seminars and just license the names of famous people multiple Sharks from Shark Tank, almost anyone who has a show on HGTV etc.
