I have never rented a house privately. I've had a mortgage for 6 years and before that I rented through housing association. If I go into a letting agent can I negotiate a monthly rent for lower than is advertised? Say a house is showing £700 pcm can I say I want to pay £600 and then we haggle to £650 for instance or will they just tell me to bugger off? If I was buying a house I would offer less than the advertised price so does renting work the same way? We only want to rent for 6 months until we buy again.
