I wrote a completely different ad that focused on some of the buildings unique design features.

@Charles CooperHello and Welcome to BiggerPockets, the Best Real Estate site on the web.

My lease agreement has a clause that personal property may not be stored outside of the apartment or designated storage areas, and that anything other than a personal vehicle is not allowed to be kept on the outside on the property.  

Or search the web.  

If you built to sell right away, did you have an architect design the home or was a buyer lined up before-hand who designed their home?

There's many web sites to advertise your property, be sure to put in the body that a background and credit check are required.

I put together my first welcome kit, and included a handwritten note on a custom-designed card from my graphic artist sister. included a coupon card.....the new move-ins looked like they rather i gifted them a taser so i wouldn't come back

I get in there and they painted , designs on the walls , all the trim pink , and purple .

Just find an architect who has small multifamily experience, design your three units, and move ahead, forget the other property, you could be waiting and miss the market.My thread outlines the development process on a small project similar to yours from your description.

Why not design your floor plan in 2' increments?
