The only way I am aware of putting in a bid is verbally from the brokers form the largest firms i.e. Foxtons, Hamptons, Chard, etc. Another one went as far to mention that it compared to putting in an offer for a house. They told me if I pay up to a year in advance I could get a substantial amount off. What they didn't mention is what type of bid I should be putting in and I don't trust them enough for this advice so that is why I am here. So yes, it is a renter's market, but there are also landlords who are dependant on paying for their mortgages with tenants who are in contract as long as possible.
