To use conventional financing, you'll need to have owned the property for at least 12 months and you'd need to close in your name.

@Stacie Telles Assuming you took out a conventional mortgage on the property you won't be able to refinance for at least 12 months.

@Summer Shelton, FHA allows you to use rental income and so does Fannie Mae/Conventional loans.

Also for conventional financing, the DP can't be borrowed.

Your goal is to plant the idea in their mind and create a situation where selling to you feels like the easiest and most logical solution for them.If you haven’t already, the first step is to get pre-approved for a mortgage so you know what you could afford if you were to purchase the property conventionally.

Two separate property appraisers (at the direction of the lender) were sent out to appraise, and neither was willing to appraise it as a "residence", and thus financing fell through (conventional primary loan).

Conventional How did you add value to the deal?

On the consumer side with QM I can handle conventional, FHA, VA, and USDA.

My professional background is data science / analytics, which means analyzing cash flows will probably come more naturally than building relationships, which apparently, is how one finds deals worth making.Are there meetups in these areas I should attend (digitally at first, presumably)? 

Conventional (only Freddie Mac See Section 5102.4 of Freddie Selling guide).
