That's not the same as paying cash.According to a different post, your credit card debt costs you $600/month.

Quote from @Na Wilson: I have a source (depending on credit score) that can do a 90% LTV DSCR loan on non-owner occupied real estate. 

I have them process credit card payments.

Quote from @Raymond Kalonji: In your opinion, what would be a reasonable minimum credit score?

Great Lakes Credit Union HSBC 70%, for premier clients only Huntington 75% LTV Hurst Lending and Insurance Investment property HELOC in Texas.

If you do not get that tax credit its usually not profitable.

If you're unwilling to charge a common fee, I wonder how you're going to handle a problematic tenant who is late on rent or responsible for paying the plumber to remove a kid's underwear from a clogged toilet.How will you conduct a credit/criminal screening without an electronic application?

Real estate investmnets are capital intensive and if you don't have extra money sitting around to make the emergency repair when it happens you'll find yourself in a terrible position.
