Here’s the bottom line; unless the deal is VERY large, or the sponsor is going to syndicate a large number of deals, the investor will make more money purchasing the property theirselves with a option low to moderate interest rate loan.  

Private lenders tend to focus more on the value of the asset or project rather than your credit score or financial history.

I applaud you for putting it out there but 1) maintenance/cap ex is far too low for a duplex 2) no PM. 3) vacancy at 1% will be challenging if achieving near market rent.

The only example I can think of is that I asked an applicant questions about their credit report.

I was initially drawn in by the low fee, which has since fluctuated, but may still be the lowest out there.

This includes credit, criminal, and rental history checks for all parties.

Keeps costs low and guests satisfied!

Additionally, since my parents are nearing the retirement age, I'd like to prioritize low-debt, high-cashflow deals.

You can go as low as 2.5x in some cases but NJ tends to produce enough traffic/applicants where 3x should be minimum unless property is over priced.

Looking at this mathematically, if you assume a 50% non-renewal rate (industry standard) and use the low end of the range of $5,000 per non-renewal, there is a loss of $50,000 per year on a 20 unit property.
