@Andrew K. Andrew thanks for the post!
I have underwritten a lot of deals in the San Antonio area, I would say a majority of them are coin stores mostly due to the demographics. Both have their pros and cons, and card systems are expensive (40-60k), if the market doesn't call for the card system I would probably try to start without one.
In terms of purchasing an existing store, the numbers have to make sense. If you can look at some P&L's, look for inefficiencies, for laundry, the biggest one is utilities. New equipment can really drive down these costs and create a fresh allure for customers, bringing in new business from competition. A new location will require high investment costs, construction, TI, and new equipment, but ROI may be higher after the first year.
For leases, I always recommend 10 yr with at least 1 5yr option, this is because equipment debt will typically be a 10 year note for a full retool. (Feel free to message for any further info on detailed financing structures, rates, and costs)
If you have any potential locations in mind let me know, I can definitely offer more detailed insight!
