Your son is responsible for making payments on time or ruining this seller's credit. 

Local banks and smaller credit unions are most aggressive in this space.

It’s not necessarily more difficult than market-rate rentals, just different.If you’re seriously considering this route, feel free to reach out.

Quote from @Argel Algura: Hey Bigger Pockets Community,A year ago I wrote about rebuilding and starting over in life and considering real estate investing as a path (see post here: "Bad credit, minimal cash and starting over in life . . .

Sounds like the person knew what was going on with their credit report as they have filed reports in the past. 

My credit score is currently 807 if that changes anything. 

If everything else checks out (credit, talked to her employer, background check, etc), I would try to validate the story with the landlord.

It may be worth letting them know about the prequalification requirements (credit score over xxx, salary above xx,ooo/year, etc.) in advance to weed people out.

You will report worldwide income on your federal and Kansas tax returns.You will also include the MO activity on your KS return.Your MO return will only include the acitivity within that state, which in this case, is the rental property.In the future, if you have income in MO(either through the sale of the property or through rental income), you will pay tax to MO but KS will give you a credit for any taxes you pay to MO.best of luck

For context I am a full time lender and understand DTI and have very good credit.
