Your credit score will be worth improving to acquire better financing options.

Caution:  Personal credit card financing is a huge risk and good luck finding 0 percent interest today.

The sub 550 credit score people come out of the woodwork to apply for this home. 

Hi Anthony, it sounds like you’re in a good position to start building your STR portfolio, especially with no debt, great credit, and rent-free living!

Quote from @Jaycee Greene: Assuming you pay asking price, I'd estimate the down payment for something like that using a hard money loan (HML) would be around 40% of the purchase price and your monthly payment would be $2,600 with an interest rate in the low 7% range (probably need a 700+ credit score to get that).

The credit score is the single best indicator of how one pays their financial obligations.

I would pay them separately rather than giving a rent credit.

Rate will be highly dependent on loan size, credit score, LTV, location, and property type, as well as a few other factors.

Since FHA is not an option, i would advise that your seller needs to work on their credit score and savings to qualify for a conventional loan.

Credit is in order and I have a steady income.
