But if you ever get a damaged piece, you can heat gun it, chisel it out and lay a new piece right in the slot. 

I do not think there needs to be a dedicated time slots for laundry, but this is something you can communicate around having shared laundry area and talking about preferences around times and days.

The biggest impactor is where you've slotted yourself.

I know in Washington state, you can't rent out multiple slots to people with their own tiny homes unless you are classified as an RV park.  

The 83,000-square-foot casino houses 2,300 slots, 63 table games, and a high-limit room.

The old meter slot is covered and this now becomes the sub-panel servicing all the circuits in the existing houseCan't stress enough the importance of planning for all utilities (electric, water, sewer & gas) from the get-go because these can very easily become showstoppers. 

Look at 2 to 4 unit building that you can use your mortgage slots for.. cash flow is better and your there to over see it.. nothing worse than being 3 states away and your having issues.

I've found nice pool tables there too, as well as video games and slot machines....

Sounds like if you free up 1 conventional slot, you can buy 2 financed properties with a 1031 exchange. 

I installed a mail slot in my storage room and called it number 14!
