While I do not live in ID, I'd love to connect you with one of the best agents out there.

I lived there for a couple years and I met this guy who has bought and managed a ton of property there. 

I live in the Las Vegas market and have investments and a real estate brokerage in Henderson.

There's definitely a few things to note since you are residing in Europe, most of the investors we work with that live over there do put it in an entity but there are a few details for how that would work since you aren't necessarily local. 

He lives locally, is very responsive.

If I live a busy life and don't have the time or care to invest on my own, but want to put, lets say $200k to work, is a 15% cash flow return reasonable?

I'm imagining something more like add a wall, turn a bedroom into a kitchen-living on one side and a formal dining room into a bedroom on the other side, maybe add a half bath in each unit.

I live in a rural market and this type of issue with technology may not be as big a factor in urban areas.

Additionally, I am beginning to believe you don't live there to be the "house monitor" as this seems to be going on for a time period.
