I have completed a lot of BRRRR projects and those are usually in the 50% range.  

Not 1 time has a standard rental poo-decorated a unit, not 1 time have I had dead bodies at a standard rental. 

I'm wondering if there are any non-conventional lenders who loan for this price range. 

This is for mid-range quality and minimal assembly items- what you save in purchase price you will lose in replacement and assembly costs!

PMI could be in the $80-$100/month range if you have fairly good credit so lets use $90/month.

Personally, in Worcester, I think $600Kish is a good range for a 9 bed 3 bath based off the revenue.

I don't have a problem with reasonable protections for tenants from slumlords but those should always be arbitrated by either a court, or maybe an extrajudicial body to free up the courts and hear issues. 

.$$ Range = max 350kDown payment = max 25%Goal = Positive cash flow and appreciation(if possible)I'm thinking about 2 options. 1.

For borrowers with low or mid-range credit scores, what are some strategies for securing hard money loans?

You mentioned rental opp by the room in the higher price range may be a good option.
