Depends on the jurisdiction. Since ownership of property, and construction of buildings on it, is generally registered with a government, there is a lot of data in existence, and most of it is public record. Alas, much of it is on paper, and possibly scattered among offices (the property deed in one place, construction-code approvals in another place, etc.).

Some governments have digitized their property registers, though. The most comprehensive one I've found is in Denmark, which has made the property register for the whole country searchable/browsable: http://www.ois.dk

Example: select "Københavns Kommune" from the dropdown box at top-right, type "Vesterbrogade" in the box labeled "Vejnavn", then click "Søg". You'll get a list of all buildings with street addresses on Vesterbrogade, one of the thoroughfares in Copenhagen. If you click on an individual address, you'll get information about the building and a listing of any subunits, e.g. that there are 5 floors, with 2 units on the 1st floor, 1 on the 2nd, etc. Click on any individual unit and you'll get information on everything from number of rooms, to when it was most recently renovated, to what materials are used in the construction.

In the U.S., some cities and counties are starting to provide at least some of this kind of information. For example, for Seattle, you can try the King County Parcel Viewer: http://www.kingcounty.gov/operations/GIS/PropResearch/Parcel...

I'm one of the founders of http://www.RealScout.com, and we're building software that lets you search by wants like house faces east, within 0.25 miles of a Google shuttle stop, open floor plans, remodeled kitchens, and hundreds of other criteria.

We get much of our data from sources other than the MLS, so it's far more accurate than some of the descriptions from listing agents that national search portals query. We also have search pages (http://www.realscout.com/categories) that allow you to view all the photos of the features you're searching for. In other words, you can see all the backyards of Palo Alto listings on one page.

Our software is still in beta, but we're rolling out new functionality daily.

#1, #2 and #5 just mean starting with Zillow, Trulia, or any other site that lets you search using a satellite map. You enter your price range, # of bedrooms and other requirements, then zoom in and start scrolling the map through neighborhoods you'd consider. The price tags appear above the houses that are for sale/rent, and you can easily see what direction they face, whether they're on the corner and whether they have a garage.

You can pan through the map of an entire county in under an hour.

This is the easiest and most enjoyable part of the home search IMO.

If I had to guess...

The information you're interested probably can't be easily/cost-effectively collected, validated or maintained.

Just ask yourself, where accurate, up-to-date, consistent information on 100M+ apartments and houses going to come from?

We've been looking at moving FAR away and the sorts of things I want to know is information about the part of town the property is in... crime rates, demographics, etc.

http://www.city-data.com/ is pretty good for this sort of information. The forums are very active so feel free to ask subjective questions that are particular for your situation.

For example, http://www.city-data.com/city/West-Linn-Oregon.html http://www.city-data.com/forum/portland/37192-lake-oswego-vs...

Assuming all the data can be gathered in some way with Google Maps, they have NSWE coords. You get an Address and there will be mostly the face direction of any house.

Have to totally agree. Looking right now for a house around North Denver. The search part of the equation is horrible.

There are at least a half dozen ways to get this information when it comes to property for sale.

There are many services that offer a great house hunting experience, but in practice, searching for housing means wading through many false positives, stale listings, contradictory information within a listing, horrible or missing pictures, and scams (mostly limited to CraigsList). Demographic information (crime, schools, etc.) from Zillow and Trulia is difficult to navigate and not well organized. The space is definitely better than it was a few short years ago, but there's a lot of room left for improvement.
