Re: leasing a location w/bad credit.
Unfortunately, probably not. =(
Companies usually look for 2-3 years of payments history.
Also, that's only a small portion of whats needed. In addition to payment history, they'll look at credit scores, debt-to-income ratio, assets, income, etc.
What about renting space from another studio ($1500/mo seems outrageous). Maybe try a Karate or MMA studio?
