How can I say this without offending anyone? In this area the Tube/transport is pretty important for the price of the house (I'm currently house hunting). When I see what appears to be a well priced house in the area, there is usually something wrong and it's usually location.
My general things to avoid are : very hilly areas, properties where the land slopes down towards the house, gardens which face East or North (unless very long), anything further than 1 mile from a tube station.
Things which I, and I would imagine others am currently looking for are: small supermarket or bigger within walking distance, London Borough postal address so free Oyster card if retired, a flat ish entry and exit to the property (I. E. a step or two is OK to the front door but no more), easy parking on the front drive plus easy parking in the road for visitors and so on.
My point is, don't get seduced by the inside and outside of a beautiful house. If it's not in the right place, and if it doesn't fit other commonly required criteria then it's won't be right for other people and will be difficult to sell.
In time, you can change all sorts of things inside the house that you hate but you can't change the location. Be happy with the things that you can't change before you buy.
One more idea OP, look at Highams Park area on the Woodford side of the station. 20ish mins to Liverpool Street and a huge Tesco with 3 hours free parking next door. It's coming up but still a bit cheaper than other local areas. Good luck.
