There is no other statistic like this!

If you can resell and make a profit then it is fine but you can not bank on it.No statistics or data can define your strategy.

"Since 07/09") to get statistics for virtually any loan by about any parameter you want.

And you had perfectly good assets being lost as the loans matured there was no way to refi and the underlying lenders foreclosed on perfectly good working assets because the owners could not retire debt in cash they had always banked on the ( OH MY BANK WILL roll the 20 due in 5 over they always have).. when they did not boom.. but I don't want to dwell on it I darn near ended up a statistic and its way in the rear view mirror.. but a combination of mortgage market  liar loans  credit freeze .. build stopped  jobs lost this all fed into it.take our PDX market .. 10k homes or doors built a year or more from 1990 to 2008... 2009   700 total that's all.. next year 1500 next year 2500 next year 3500 next year 5000 plus.. 

Meaning, in a smaller market, sure it may be "small", but it is also going to have less investors (aka competition); whereas in the bigger markets, sure there are more houses, but you can bet your bottom dollar that there are also more investors who want those houses along with you.I have no idea what it is (and I'm guessing the statistic isn't even tracked, let alone how it could be), but it'd be interesting to know what the "investor per home" ratio is in different markets.

Trash, landscaping weeds in the sidewalk cracks, the appearance of people hanging around, Are all subjective and difficult to add to a formula.Some things like; the types of cars in the neighborhood, crime statistics, Populations growth or decline and other various demographic info, Permits for new construction, forecosures, etc etc while quantifyable are not easily and consitently found from a relliable source.

I currently sell cars as my "DAY JOB" and statistics will tell you that 81% of customers said they bought from you because they LIKED TRUSTED AND RESPECTED you.  

You can also check the crime statistics on trulia.com by typing in the property's address, clicking to your property's page and then scrolling down to the Neighborhood Info section.

Does anyone have/use a website for learning out population statistics in different areas?

It is at best a statistical guess.Mark
