Additionally we keep the total security deposit until ALL the tenants move out, so the leaving party won't get their security deposit back until the last party leaves. 

The property will last forever, but if rates go down, you can always refinance later.

I had to move twice already in the last 3 years, so when I move again, I want it to be in their forever home.I actually am already financially free.

@Allen L.i hear you on the hassle of conventional loans, my portfolio is not as large as yours but I applied for a HELOC last year and it was a huge pain. 

As best as I can tell on both sites, the algorithm looks something like this:Cheapest price>least restrictions (cancellation, # of days minimum, etc)>Premier/Super host>Review Scores>Most discounts (weekly, last minute, etc)>Regular revisions

Lastly, majority of of liens are posted in Judgement Lien Documents(JLD).

I’ve house hacked for the last 7 years and acquired a handful of properties this way.

My last Tax Deeded Property returned 233% ROI.

With my last (2 years ago), I had to take an alternative exit strategy to avoid a loss.

PLUS, if a bank decides at the last minute they don’t want to borrow you money for a new type and price range of property for you.
