I agree that Trulia is good for things like crime stats, etc.

Jeremy Peterson of Vesta Real Estate, fellow broker and analysis wonk, put together this video which examines the Ogden / Weber County market cycle. 

1 time out of 5, a property that sells for $200,000 will be "zestimated" to be worth either less than $160,000 or more than $240,000.These are stats provide by Zillow about their own accuracy (from the chart posted by Katy).Zillow is a pretty slick tool, but my opinion is that you should do your own comparable sales (or ask your real estate agent to do/help with it).

I don't really have much real advice here, but on top of what the others have said, I'd recommend doing some research into the stats about the influence of money coming down from Vancouver.

Therefore I would recommend having a lease that someone else provides to you examined by a Real Estate attorney.Good luck.

Member directory, bulk emails/SMS, group administration, surveys, visitor stats, custom emails/site domains, but most all capabilities (other than calendars, directory, and custom pages are all under the $25/mo pricing tier. 

Do you mean pulling stats out of certain areas?

I recently passed my exam in california and just signed with a small brokerage.

  :)I think there is some value in what you are trying to establish however if I'm understanding it correctly, this sort of 'dynamic' variable that can be attached to occupancy stats to help close the gaps in inaccuracy. 

Usually vacancies is tracked locally by local REI groups. but those stats focus more on multifamily.
