The first option is to use the "Cash for Keys" approach and offer them some money to move out and find somewhere else to live. 

Eventually you'll run out of money or lending potentials on your own which is usually when many investors start looking to partner up.

We all make money , good money at that .

So the landlord could charge (say) 3.5% and choose to make money on accepting cards… but rentec direct’s charge 2.95%.  

It's scary, money is real, and you have to run your own race based on your circumstances and finances. 

Bought it with hard money and then refinanced in a long term DSCR loan.

Then when you inform the newbie of the reality of dong subject to transactions, or I inform them about the pitfalls of originating hard money commercial loans, they accuse us of being bias, killing their dream, "hating" them, etc.  

I have a high credit score, good income, and money in the bank, but I have been having a difficult time finding a DSCR lender I feel like I can trust.

Unfortunately I've injected every last dollar that I have on this project so borrowing or putting in my own money is not even close to an option.

You can make or lose a pile of money in any of those.
