Newer properties have been gut rehabbed with layout changes to accommodate a more modern floorplan with bigger bedrooms, but the smaller 2-4 units commonly have tiny bedrooms in those areas

It's a nice house but a 500K price yelds a pickier client range and not exactly the layout they may want. 

At 1800 sq ft, 2/1.5 each, Id be looking at how the layout lends itself to creating an additional bedroom to increase both the value and the rent.

@Mark Bookhagen - here is the basic layout of what we put together. 

I'll try my best as a novice to lay out the numbers of both: Based on today's values, I've been told by a couple of realtors that list price would be just under $400k, with the expectation that negotiations would bring that down to a conservative estimate of $365k (which seems high to me because it's almost $100k more than I bought the house for 3 yrs ago).

It's shocking especially because the website is amazing - layout, design and features. 

Secondly, I would assure yourself that your layout is good for a rental unit or is there any or a large number of people that demand that layout or that location. 

I am having trouble locating this home style on google, when searching for photos of similar homes.I would normally call it an "L-Shaped Tri-Level" or "L-Shaped Split-Level" but if you pull up a google image search with those phrases, nothing shows an attached garage in this manner.Is there a better name for this type of layout that I am missing, specifically, with a front-attached garage as shown?

Is an email enough for listing agent to send it to seller with purchase price, estimated closing date, and terms . if the email is your option can you gave me an idea of  how you lay out that email.

I'm still trying to learn the layout here on BP.
