First time buyer making a low offer

1987_l

I am looking to buy a property i am a first time buyer the house that i have seen is a new build it was completed in 2010 its still on the market on at £230 it is a 3 bed detached way over priced. The builder has removed it from one agent and put it for sale by another agent. As it is new build a 15% deposit is needed. Its been on the market 2-3 years could i offer in the region of £160 or is this way to low any advice is apreciated.
