I'm house-hunting at the moment and I'm trying to geek it out er I mean streamline the decision-making process.

I'm currently using google maps's "my maps" feature to store pins to properties. I create one map per estate agent, then put relevant into into the individual pins. The idea being, I can look at the map and quickly choose which property to view next.

However the pins don't currently link back to the map they're owned by, so you have to hunt a bit to get the estate agent info, it's a hassle to get all maps displayed in a new session if you have lots of agents, and each pin doesn't automatically show its bubble so you have to do lots of clicking to see all the info you want.

I've tried Evernote, but despite its tag system initially showing some promise, I can't find a way to seemlessly integrate maps. A few google searches don't turn anything up either.

Even the big sites, like http://www.rightmove.co.uk, don't seem to provide any maps integration by default. You can see an individual house's location, but not all results of a search.

So is there a web site or windows program I could use to do something like this? Viewing all properties on a map is a must, as is quick access to contact details.
