When you are considering various lease options, consider subleasing office space. You can often secure highly upgraded space with high end interior finish at no additional cost. In addition, the length of the lease term is generally shorter, therefore you have less of a financial obligation. Credit requirements and security deposits are generally less stringent.
Rental rates are more negotiable but do not expect generous tenant improvement packages from the Sub-landlord. Keep in mind that the paperwork is sometimes cumbersome as you have to execute a sublease agreement and a Consent Letter with the Prime Landlord.
