Required good credit, adequate reserves, full doc commercial loan with a personal guarantee.  

@Enrique Toledo  If the seller is firm at 10% down, you can always get a personal loan for that 10%. 

However, I'm short on cash (will be putting $20k of my personal money into this)  and I am exploring creative ways to source funds for the project.I’ve been quoted for a $100K HELOC on my primary residence with a 30/1m ARM at a 13.25% rate and APR, with an interest-only monthly payment of $1,016 and $3,825 in points.

I personally would avoid over investing in this unit.

I personally like index fund investing in funds like VOO.  

Now the tenant may have a legitimate personal injury claim and more.3) "Citing Renters Insurance declined coverage"- So, tenant has Renters Insurance?

Whichever direction you go, be sure to work with folks who understand this and gives you the confidence to take reasonable action - I'd personally take an okay investment and weather the storm for a few years that will eventually perform well, and do that each year - rather than take 3 years to wait for the best deal possible.
