How many outstanding loans can I take?
Payday Loans as well as other short-term cash advance are strictly regulated by the state's law. It can state the amount, the APR, the terms, the number of loans, rollovers, etc.
In most states it’s only one loan at a time. In the others it either not stated, or restricted to 2 cash advances. Usually if you have a good credit history the lender can let you have several loans simultaneously.
