I've worked for Superstar Car Wash, Circle K, and The Carioca Company. 

If accepting the no parking MTR situation, then the MTR really needs to be pet-friendly (bonus if fenced-in yard) and have laundry (especially in-unit) to make up for the elimination of a key amenity.

Finished basement with an added bedroom and enclosed laundry area.

-If its a large house that has a dedicated laundry room on the first floor, throw in stackable  laundry units on the bedroom floor.

I would not credit for laundry, I would price in line with not having a laundry if other units do.

There are cheaper one’s in D/F areas but I would be careful as those can create a laundry list of additional issues.

Or maybe you finally want to purchase a multi-family complex / self-storage facility / car wash, etc.

Also, for your shared laundry situation, I recommend PayRange.

Licensed with permits ~$4,000.Full replacement of all water supply lines and shutoffs from the interior water meter with PEX and an open basement.  1 kitchen 1 bath 1 laundry. 

We are still using some towels after 7 years of use as well as all the sheets since we started.The key to those is washing them right.
