Drew,It sounds like you need to make it out to some of our investor networking events here in Wichita. 

Being new to this can be risky.

More specific: He stole months of rent and utility payments from a tenant (and threatened to evict her!)

There are stated or no income 2nd mortgage loans but typically these are fixed term and fixed payment type second mortgages meaning the interest rate usually doesnt fluctuate like a HELOC or home equity line of credit would fluctuate (prime + margin = annual rate calculated based on a monthly basis). 

I had a decent set of renters that are leaving after their lease is up at the end of this month.

This is what I have done on all my other rentals, but am trying to maximize my cash to buy multiple properties. 

If you want to explore MF or any other asset class, the best course is to go to some training courses and get a coach or mentor. 

If this is a longer term hold and you don't need the extra $500 per month and you'd be fine with a $200 per month increase, go for that.

Want to store and spend $50,000-$100,000-$1,000,000 in cash every month. 

@Keonhee Cho1. to BRRRR you probably have to buy a deal off market.
