The more money you ask the landlord to spend getting your space ready for your lease, the less flexible they will be on rate. New paint, carpet and walls might seem like a benefit to the landlord too but it is really just seen as an expense. By the time your lease is up the space will need to be updated again from wear and tear and different preferences of the next tenant. You can negotiate better lease rates if you can find a space that substantially meets your needs as-is. The cost savings to the landlord can be realized in a lower negotiated rental rate.
