I originally thought you might covert it into a true duplex with two distinct units, was that not feasible for the house?

That would differ a bit from the wholesaling strategy I think you were mentioning, given that I don't have the funds to put properties under contract right now, but I'd be interested in hearing your thoughts on the distinctions between those two strategies.

I'm guessing that's still less than the maintenance costs of filing and maintaining 2 distinct LLCs, (75$ each) though we'll also pay someone to file those 1065s forms (at least in year 1 and 2 to be sure we're doing it right) which we wouldn't have to do if we had two LLCs. 

I think there is an important distinction between marketing and showings on a property.

Here's a possible legal distinction. 

This is a point that is distinctive for whole life.

Shawn:If you are renting by the room, lenders will be disposed to see it as a rooming house (whether it is zoned as such or not) - particularly if the appraiser finds distinct evidence (i.e. locks on all bedrooms). 

I don't understand the distinction between a showing agent and an agent when you passed the same test.

I don't even hear the nicknames "Methmont" or "Stabmont" being used much anymore ;) Not to be a stickler but I wouldn't really call it "outside Denver" as it's 45 minutes away and a distinct town from the metro, not a true burb like Arvada, Westminster, Lakewood, Littleton, Centennial, Highlands Ranch, Aurora, Greenwood Village, Commerce City, Northglenn, Englewood, Glendale, Thornton etc.etc.etc....
