But I am looking to scale my portfolio more quickly which leaves me with a few options.

The other 1 out of 10 understood, told me there were no options, and then went on a rant about how most insurance brokers don't really know what they're doing and just care about making the sale.In most cases you have to find a small local company/agent for this kind of coverage. 

If you have no other options, sure, go for it; however, if at all possible, buy a single family home.

There are 80% options available, but often they come with chunky origination fees. 

I know I have other options like selling the notes or partialling, but this question is more focused on taking collateral based loans against the notes.

@Geraldine ChurchwellGo to youtube; search Joe Crump wholesaling lease options.   

Hence I’m still keeping DSTs as a future option.

I have non qualified stock options through my W2 employer now that has potential in about 5-8 years to exercise.

Is airbnb a good option here?

Evaluate your budget, savings, and potential financing options.
