Boring Novato PoS

This boring 1419 sq ft Novato PoS last sold for $598,000 in April of 2004. The exact same upgrades that are in place today (just a remodeled kitchen and some French doors, no granite, sorry) were originally put in before April of 2004. Today you have to spend $730,000 for this same PoS. So this place is selling for 18% more with absolutely no changes (other than being used) since the last time it sold. So in your opinion, dear reader, has Marin become 18% nicer than it was 18 months ago? Or are there now 18% more people trying to buy in Marin? Or are there now 18% fewer houses in Marin? Or is Marin's crappy public infrastructure now 18% better than it was 18 months ago? Or is the sky over Marin now 18% bluer? Or is it just that buyers are now 18% less discriminating?
