You can buy a laundromat for free through seller financing. Seller financing is easier to attain for laundromats than it is for real estate.
You can also open a laundromat business with little to no money down by getting a business grant or by starting a laundry business from your home and growing your profits for investment and expansion.
When buying a laundromat, you should ask about the average monthly operating costs, how old the laundry equipment is, what repairs have been done on the laundry equipment, and if all the machines and other equipment are paid for.
