The flip was extremely challenging - original plaster walls, original mud bed tile and lathe, heavy ciggarette residue throughout, complete bathroom framing and subfloor replacement needed, and a challenging layout.

If you are having to do serious electric , plumbing, HVAC, or layout changes, it probably won't work out well. 

We flipped the layout and you can now see the bedroom entrance door across the way.

It was not done well, there is a hodgepodge of 'handyman/diy" work throughout, and I'm trying to decide if we fix it up right or just make do until we sell in 10-15 years.The two units are ~3bd, 1ba and about 950 SQFT each, with less than ideal layout but otherwise are ok cosmetically, and the property is fairly large and has a nice yard for the area (South Seattle near Light Rail).

This is a 100+ yr old brownstone, the layout of the basement does not allow for storage cages and with the 3 boilers, water heaters, and where the utilities/sewer line etc are arranged there isn't a way to accommodate storage without blocking access to the circuit breakers, meters, or the basement's bulkhead doors.

I'm looking for layout ideas and a design that looks a little nicer than a generic building and maximizes the limited space I have.

I should have made it a couple feet wider so the walk in closet didn't impede on the space so much and make it look like an awkward layout.

They have a very small but efficient kitchen layout. with everything you need and space for a bed.

Depending on size and layout of MH maybe get two smaller output units.  

Then we re-configured the layout, and used better material.
