It is tricky, we looked at buying in those areas recently (hence knowing the bloody catchments off by heart!) and the jump in prices when you cross over in to the Granton catchment is pretty big. We were also looking at your sort of budget
Few other places I can think of that get quite good schools in that sort of budget would be:
- Clermiston (feeds to Royal High) - more north west than north, some dodgy bits but some pretty nice and IME probably nicer than Granton (lived in Granton so not being mean :) )
-the edge of Silverknowes on the border with Davidsons Mains. This is one to study catchment maps with care but there are a few Silverknowes streets which feed to Davidsons Mains Primary, and then on to Royal High
-Butt ugly, but Saunders Street flats in Stockbridge aren't too far off that budget
-you get the odd reasonable property in the Blackhall catchment - this for eg
-if you don't mind slightly dull flats then there are a few other options. East and West Court in Ravelston House Park (none on the market right now but info here go for under £200k for a 3 bed, are a decent size and Blackhall/Royal High catchment. They're the random dull blocks in a lovely area and pretty spacious.
-Barnton flats here - either davidsons mains or cramond primary, and royal high
Slightly wild card option as it's the other side of town but I know quite a few families who have moved to Buckstone, which has a good primary and then feeds to Boroughmuir for high school. [[http://www.espc.com/properties/details.aspx?pid=334450 this just under offer @ 210 )
