Anyone use Rent-o-meter to get idea of rents in the area?

[Michael Lerch]

I came across this interesting website called rentOmeter that checks a person's current rent (based on how many bedrooms) against other similar bedroom rentals in the same area.

I've been using it to guesstimate rents I could get for properties after they're fixed up for landlords. I'm not quite sure how or where they get the rent info from so I don't know it's accurate. I don't think I'm allowed to put a link to it here so you'll just have to google it.

What do you guys think? Good or bad tool to use? Is there something else out there that is as convenient besides knocking on doors and asking?
