We moved from Zone 2 London to Zone 3 this month and decided to rent for a year to get a feel for the area and decide what/where to buy. "We" are husband, Year 4 DD (who has complex needs), Year 3 DD and Y1 DS.
The place we rented was pretty much literally the first place we saw, and I was honestly expecting it to be fine but not more. But everyone - including me - absolutely loves it. Small but really nice garden (south facing), great sound-proofing, 5 minute walk to school. DD2 and DS get on really well with the similar age kids next door, and DD1 has been so much calmer and happier here. Husband has a quick commute to school (10 mins on the Overground) and the kitchen is amazing.
I'm afraid that we're all going to be so gutted to have to leave!!
