OP, please take any feedback with a truckload of salt: I have very rarely, if ever, come across a reply to this type of questions that wasn’t along the lines of “wherever I live is best”. That’s not particularly useful – I think a list of pros and cons, of why some people may prefer one location while other people another one, etc, is way more useful.
From what I remember from our househunting, the area south of the Earlsfield station (eg Isis street etc) tends to be more expensive than the area north of the station (Vanderbilt road etc). Maybe because that’s where what little high street Earlsfield has is, or maybe because Earlsfield Primary is considered outstanding, but beware of paying too high a premium for an outstanding school: ratings change all the time, what if in 5 years’ time Floreat becomes outstanding and Earlsfield Primary good?
Houses along Earlsfield road, especially from Brocklebank road upwards, towards Wansworth Common, tend to be bigger, but of course you’re going farther from the station. Beware of houses overlooking the tracks: some are huge and beautiful, but good luck selling them: most people wouldn’t even view a property near the tracks, and I can’t blame them.
North of Swaffield / Kimber road it tends to be a bit cheaper. From there you can probably get into Swaffield or Floreat, but of course you are not too close to the station. Beware that Garrat lane is busy and the buses taking you from Southside to the train station are not the most reliable. Another slightly cheaper micro-area is that around Swaby gardens – understandable as most houses tend to look less nice.
The only criticism I have heard from Earlsfield parents is that the area doesn’t have a good state co-ed secondary. The Southfields Academy polarises opinions – not everyone seems to like it. Balham has Chestnut Grove, and Putney has Ashcroft.
Do you have a car? I wouldn’t recommend Earlsfield for a young family without a car. The high street is almost non-existent, the two supermarkets are very small, and going to the Southside by bus with a pram and lots of bags of groceries is not very convenient. By contrast, Balham or Putney are more convenient if you don’t have a car.
I’d say Earlsfield has less than areas like Putney, Balham, Northcote road (all more expensive) but more in the immediate vicinity, because it takes you a few minutes by train to get to Wimbledon, or a few minutes by car to get to the Southside mall.
Have you considered Southside? The high street isn't much but Wimbledon park nearby is lovely. There's a branch of the district line, which isn't the most reliable, so it depends on your commute - there are quite a few areas that are easier to reach by train from Earlsfield than by tube from Southside.
Are you looking to buy or to rent? What will your commute be like?
You may have heard about the South West Rail strikes so that’s something to keep an eye on.
