Quote from @Bonnie Low: I agree with Carolyn that MTR is a pretty safe pivot if the numbers work for you since the STR scene is still a little unclear.

I have a rental that has a great rate and low mortgage so I make a nice amount of income from it .

On one hand I don't file it as a rental property, on the other hand I file as a rental with the low rental income. 

If at all possible, I'd suggest beginning with a house hack because it should cut down your own monthly expenses while you build equity and there are great low down payment programs available for owner-occupied financing.

I think you can find high 300s, low 400s.

I do run credit & background checks that they pay for, but that is separate from just the application.

Rent rates were low for our area which we have been able to raise those higher than we even expected.

OR, if you're able to assume a low interest rate FHA or VA mortgage (but you need to have the difference in price vs the loan balance), that's an option too. 

With my low rent when I calculate the numbers for a duplex I would pay the same I pay in rent while I live there.

What's the best business bank account and the best business credit card?
