Believe it or not, I actually prayed for Osama bin Laden.

Some of my favorite features: adding a few updated light fixtures (like a chandelier above the stairs, or wall sconces on a feature wall), adding an accent wall, including some floating shelves, exposing brick where possible, etc.

To be upfront and honest I am & will be a bit light on exact perfect detail and mechanics as 1) it is very detail laden, and 2) not really interested in broadcasting my hard earned "secret recipe" that have developed over the years. 

Ended up sinking about $3-4k to fix some of the interiors, take down a lot of crazy shelving, and paint just about the entire house.

I set up shelves.

Attitudes have shifted, and all but one of my drama-laden tenants have calmed down, and even explained to me that they now understand why rents have risen, and are happy to have a nicer place for their clients to come see them. 

Even though these are second tier markets, stuff is flying off the shelves.  

It looks good, but in the process they also took out two older cabinets that were hanging on the wall and installed metal shelves.

So I ripped all the sheetrock out of the room, they had screwed a pocket door closed on one wall and used a combo platter of spare lumber, particle board, shelving etc to close off the garage side wall. 

The crates are shelves.
