This can open up for liability and lawsuits in the future against both the owner and the property manager.

This kind of plays into the booking issue many have alluded to here.

What made you interested in investing in this type of deal?

Using simple numbers, assume I want to purchase a $100,000 property using crypto as collateral:- I pay the closing costs with cash- I put down 10% down payment with cash ($10,000) - I utilize a crypto mortgage for the remaining 90% ($90,000) This way, I still keep my crypto and I have a property, both of which may accrue in value over the long-term.

This is a very personal question that is difficult to answer. 

Not able to buy in this area without going house poor.

I'd recommend this strategy for a new investor vs. doing a HML on your first deal. 

In this case, Vanessa is talking about paying 8%, or $8k, in a given year on a 100k investment, so 8%.Second, "avg cash on cash, excluding sale": in her example she assumes a flat 8% paid each year, so avg would be 8%. 

You can do this too! 

This will give you a great front row seat to learn.
