I think flight noise is a little different between MM and SV. I see planes fly north west a lot, so I assume their flight path is north west. In SV, I would have to speak a lot louder or stop when the planes are directly on top of you, while in MM, it’s not nearly as bad. If you’re looking for 2000+ sq-ft houses, NW MM will be on average ~30k more than SW MM for a comparable house. They will be building a new elementary school for SW MM (starting this Summer) if that matters to you. The biggest differences for me when looking at 2000+ sq-ft houses in MM and comparing NW and SW MM is the HOA. Because of HOA, NW MM will look more well maintained while SW MM is a more hit and miss depending on the owner. However, due to the fact that there’s no HOA, you tend to see a lot more big trees.
This house: http://www.sdlookup.com/MLS-110019029-10555_Dabney_Dr_San_Diego_CA_92126 went pending after just a week on the market. Not sure what it’ll close at, but since it’s only on the market for 1 week, my guess is it’ll be closer to the high end of the asking price. Similar property in NW MM would probably sell for low to mid 500k.
