I do not understand your remark as related to the DSCR loan.  2 ADUs are not allowed by f/f conventional financing but is not always enforced.Fortunately if you stay with the current tenant without a refi, by the time you pay principle it is likely the rent will have increased enough to absorb the increase mortgage payment. 

I like 3x gross rent scenario, no past evictions, and a credit score of 600+ 

I don't currently have any investment properties, but will likely work with a turn-key property managment in the Memphis/Little Rock area.My goal is to build a good cash-flow portfolio to ease into retirement. 

I think of it like an employee or personal assistant.

I suspect I can build this in 6 to 10 hours, but it is always helpful to have another brain on the job. 3) There is an advanced function I would like to build, but sadly I can't recall the mathematical functions necessary to make the calculations.

We're looking to gather info about likely cost, pitfalls, time required, considerations when obtaining financing, etc. 

Knowing the rent will likely show up each month—even if the tenant has challenges—removes a lot of the uncertainty that can come with rentals.The people listing this apartment as a “Section 8 property” are likely trying to target buyers who value that stability.
