I live in West LA and work in commercial real estate finance so have experience with analyzing deals.

(West of San Mateo, East of Girard, North of Central, South of I-40).

There were zero comps pulled from west of Troost.

We currently live and invest west of Kansas City.

I already have a home in west Michigan and have given advice to clients regarding this.

Even all the west loop. 

Raleigh now joins Durham, Charlotte, and even Cary, which has long allowed one "utility dwelling unit" within the same structure.ADUs have long been popular on the West Coast, so there's already lots of people here on BP who know about them:https://www.biggerpockets.com/blog/accessory-dwelling-units-tipshttps://www.biggerpockets.com/blog/accessory-dwelling-unit-cash-flow

I'm assuming to make this feasible I'd have to stay true to the 70% Rule, but I'm unsure this will work in my area which is West Puget Sound WA (prices are still a bit nuts in some areas, but not everywhere).

Investment Info:Single-family residence buy & hold investment in West Valley. 4 bed, 2 bath, fenced in back yard, swamp cooler What made you interested in investing in this type of deal?

There are a lot of people actively investing in west Michigan on this forum, myself included, whom I'm sure would be happy to give you some feedback on the location.
