We found our place quite by chance. We were getting NO WHERE with estate agents. Basically, they wouldn't rent to us unless we viewed the place and we were having a difficult time finding someone to view places for us. We knew the area, how much etc. we didn't really care so much about the place, just find us something in the catchment area of the school, Please!
My parents just happened to be in England on holiday and had a day travel scheduled in, so they came up and viewed a few places for us. They were unimpressed with all of them (their standards are waaaay higher than ours!) so they asked if there were any other places. The agent told them of one house that was going to be listed so she gave my parents the address and told them to drive by. No paperwork on the house had been completed with the agency. My silly dad stood outside the house, taking pictures and the woman inside came out and asked him why. She actually owned the house and invited them in and then my dad brokered a private deal with her. My dad even called me from her house! We pay considerably less than if we had gone through the agent. It was pure luck. And we'll be there as long as she'll have us!
And BTW, she was having an equally difficult time with the agency. They were no help to her at all. She was glad to be rid of them.
