One side is obviously sinking and likely continuing to sink as we found a crack in a closet along the center wall.

. $3k for the bathroom, $2k to paint, $4k to repair the fencing and $1k for blinds, outlets and closet doors.

It has a closet, smoke detector, overhead light, multiple electrical receptacles, and two sets of windows. 

Closet organizer $5-10.

For instance the laundry room was divided into three closets and a very small “hallway” where the washer and dryer sat, so I took out some walls.

I'm going to be a bit of a contrarian to the above posters, but let me first qualify my post by stating that your market will determine what you should do.We frequently install en-suite laundry in our units - in fact, we have removed common coin-op laundry in most buildings of 6-units or less in favour of en-suite laundry - for the following reasons:electricity and, in most cases, hot water costs are transferred to the tenant;where water is sub-metered, water costs are transferred to the tenant;high-efficency residential laundry machines are about half the capital costs of commercial coin-operated machines;we can command $30 - $50/month in additional rent with en-suite laundry;by installing our own machines, we know they are installed property, with catch/drain pans and {going forward} leak detect shutoffs; andwith en-suite laundry vandalism of laundry machines has been non-existant ... and if a machine is damaged, we know who is responsible.We have a good rapport with a couple of local appliance suppliers and get called whenever they have "dinged and scratched" units to unload ... a small, cosmetic dent in the side of a washer - which will never be seen when it is installed in a laundry closet - can be worth a 40 - 50% discount.  

Do you know of any short-term or system that is portable if new owner does not want to assume a contract.  

@Ray Agosto, I would look into the permit costs to add bedrooms to the basement as well as the code requirements (i.e. having closets, recessed windows, alternate exits, etc).

Note that I turned my coat closet into my office :)           

I'm getting a stackable washer/dryer for my unit and the laundry closet is quite small with a depth of 28 inches for the dryer.
