Tiled out walk in showers, huge custom walk in closet, kitchen backsplashes, and a lot more. 

Plus Home Depot has great prices on their Pro Pack bundles of the stuff.One word of caution though, be careful about using MDF on any hard surface flooring that is likely to be exposed to water (i.e. bathrooms) or mopped regularly (i.e. kitchens) as they can soak up water and get a little swollen/deformed. 

I walk into the kitchen, and a lady was in there, she went pale white in the face, she totally fell backwards and collapsed on to the kitchen floor hitting the stove and shelving.Not only did I scare her, she had a medical condition.

I visited the property yesterday, and both units are very nice (fully renovated, with very nice kitchens and baths...definitely not "builder grade" stuff), and the property is the last house on the cul-de-sac, surrounded by very nice properties, and this is the only multi in the neighborhood. 

This addition would be on top of slab/crawl (that we would have to lay) and would include an interior remodel of the kitchen, master bed/bath, and possibly another 1/2 bath. 

Also Would this be base on comps of like properties in the area, if not will it increase property value besides the usual kitchen and bathroom?. 

Since we purchased in July 2013 we gutted 1.5 bathrooms, renovated kitchen, new paint/trim and new floors.

Keep in mind rehab to prove increase in value- we've bought some really great deals that didn't need too much major work, but then when we hit appraisal time it was hard to prove a huge increase in value in 6 months time, because we hadn't put on a new roof or remodeled the kitchen.  

My guess is your asking price is too high.In my market, even if the house looks decent, rehabbers will generally be updating the kitchen and bathrooms, refinishing the floors, painting, etc. 

Your architecture skills will have greater leverage for bigger projects certainly, but the process for doing a kitchen rehab flip (for example) is a good incremental step in learning the buying-bidding-building-selling part of the market.
