I think I wasn’t clear, they are applying together as a couple who does not currently live together but would be moving in together.  

The real concern in the audit won't be the statements or checks but how what % of the expense you're applying as a business expense.  

If it is legally an SFR but is in a duplex zoning, you could apply to rezone it a duplex.

That’s nice that you want to help them @Tom Gorrell but I would suggest you have a Plan B besides Section 8.If you move them in tomorrow like you suggested, and hope to cover the rent for them until they apply for and receive Section 8, you could literally be waiting for years.

Applying with a hard money lender is equivalent to a bank as your getting a loan.

The HELOC didn’t cost us a single dollar to apply or for an appraisal of our house.

Does that mean the 90 days doesn’t apply currently?

I’m in Ontario, Canada, so a lot of the US regulations don’t apply. 

More specifically meaning if this was operated in one state on the west coast (Colorado) could you apply for a mortgage for a property on the east coast (Connecticut) and meet the mortgage requirements for pre approval.
