Very helpful for a first-time buyer. I'd had problems with other flats I'd tried to buy through other agents (hidden expenses, lack of information, etc) but had none of that with Paramount. They seem to genuinely want everyone to be happy with the deal and for it all to proceed as quickly as possible.
One complaint - the previous owner had tenants and she wanted to exchange contracts and even close before they had moved out. I had to put a stop to that, when I would have expected the agent to explain to her why it was a silly idea.
