I doubt a Traditional mortgage would be an option, I purchased my home last year. 

Very light work needed here What was the outcome?

A bank with a traditional loan Will Not, and usually legally Can Not, negotiate on loan balance unless there is a Short Sale in place.

The properties I'm currently considering are in Michigan, mostly turn key or with light rehab/value add, 1-4 units under $200k.

I live in this multi-family so I take care of the grass/lawn, snow removal in the winter, etc - however, I plan on moving out this year so I'm in the middle of deciding whether to hire someone to take care of the outside work or include it into the lease for the tenants.For the lease agreement, I used the old one the previous owners had and made small changes but there's nothing specific to snow removal, lawn care, or other general household maintenance (changing light bulbs, air filters, etc.) 

Traditional How did you add value to the deal?

Nothing yet, when the tenant moves out I'll do a light remodel.

Part of the reason I’m looking into this is for speed over traditional stick built homes :)

I have seen a retrofitted single family home with a zoning change, which did require ADA compliant modifications; the same was not true for a large single family home with traditional zoning being operated similarly).

It can be a hard pill to swallow paying 2-3x more than a traditional PM, but the obvious is that there is much more work that goes into operations and you have constant eyes and maintenance on the property.
