Negotiate!
Letting agents are desperate at the moment. I signed up to a new one in September, i got £1850 per year off the asking price on a 5 year lease (which so im told is common at the moment) but with a get out after 3 years if business circumstances change. Also, i got the first maintenance charge dropped as it is due in October and is charged every 4 years, £600.00, things like maintenance to the exterior of the building, roadways, parking area out the front of the unit ect. Also, make sure you get a solictor to look over your lease before you sign, and get your own don't use the one the landlord/letting agent uses.
