My concern is doing the cash out refi on my other rental and causing a new and much higher payment on it that I can't just pay off like a loan.

The lender may figure if the borrower had this kind of money they’d be making the mortgage payments. 

The new buyer puts down 10% as the option fee, ($50,000 fee to our buyer) in this case, and we make the rate 10% to the new buyer for the monthly payment. 

Here’s the situation:Purchase Price: $540,000Down Payment: 20%Mortgage Rate: 7.125% (30-year fixed)Monthly Expenses (Mortgage, HOA, Taxes, Insurance): $3,706Realistic Max Rent: $3,000As you can see, I’m currently short $706/month even with max rent.

She put a portion of the down payment (15K)...and of course there is a little equity...

It won't change the payment unless you refinance.

If you tried to use the app to look at photos of your ads or look at the "charges" for rent payments and such it was pretty much unreadable and would have several glitches making things overlay on top of each other and such. 

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.

Thank you and be well-ShawnT Buyers aren't necessarily interest rate shopping they are shopping for affordable payments.

Your payment went up $1,000/mo but the taxes only went up $5,200 which would be less than $450/mo.
