Congrats on the opportunity to buy a store! You certainly sound like you have plenty of experience, which is a huge plus when looking for financing. The one thing I’m a bit confused on is your rental equipment. Do you already own the equipment for your store? If so, that could be used as collateral but may not make a huge difference either way depending on your lender. You can’t use that equipment as any type of required down payment though. You’ll likely need to come up with those funds.
Your first option is to find a financial backer, investor, or partner who likes your experience and is willing to put up the money and let you work in the business. This can be harder said than done, though. Another option is to use a Rollover for Business Startups (ROBS), which gives you access to your retirement funds in a tax deferred account without paying any early withdrawal fees or tax penalties. The last option is to get a loan. I’d recommend checking out our article on how to get a loan to buy a business, if this is your only option. Good luck!
