If they can show their personal portfolio and how they and team are hands on at rehab and management over that time with high margins and conservative debt to value.   

Forgive me if these are dumb questions.

If I refi into a DSCR with 6.9% at $780,000 (75% LTV) I could pull $200,000 cash for leverage, pay $6,600 vs my current $5,600 and possibly free up some debt for another owner occ purchase.

If this is 100% your writing, please forgive me.

If the deal is residential 1-4 units, I'd aim for 30-year fixed-rate debt. 

The key is making sure the rental covers the extra debt and you have an exit plan (refi into fixed debt, pay down and etc.).

Who are the no upfront fee collections agencies that focus on consumer debt and back rent in North Carolina?

I’d rather not stretch myself too thin with debt, so I make it a priority to pay down a good amount of my portfolio.

I am working with someone right now who is equity rich cash poor and has no exit strategy except take on more debt that they cannot afford.

For instance, if there was a total of $250K of debt on those properties that woud leave you with $350K of proceeds to use to purchase $600K of real estate.
