Housenetwork has saved us many thousands of pounds. They do virtually everything that the expensive high street agent does for just a few hundred pounds. Provided you are comfortable showing prospective buyers around your home(or find a friend who is), then the MASSIVE savings are worth it.
They keep you informed and are at the end of a phone until late in the evening and at weekends or 24/7 online. Unlike other agents I have experienced, they don't switch off once you have your buyer and pass matters over to the solicitors; they chase them up regularly and work hard to help overcome any problems, whilst keeping you informed.
I have bought and sold many times and never gone back to a previously used estated agent. I won't be saying that about Housenetwork; I'll be back!
