Shops For Lease Should I Be Asked For A Deposit On A Long Lease?

Should i be asked for a deposit on a long lease? - shops for lease

I rented a studio (4 one-year lease), they want the quarterly payments, which is ok, but beyond that they want a deposit for 3 months, this is a common practice? I can not afford it, for 6 months in advance. What in the quarterly in advance is as good as a deposit!
