Their agent did them a disservice or they all knew what was going to happen (looking for the 1 in a million buyer, not caring about the data or neighborhood to put up that kind of money) just to "test it"So ask yourself this question...are you testing, or are you selling? 

Basically any credit driven data on consumers is 'gold'.

We also need to make sure there aren't too many new apartments being built, so we look at those numbers as well.We get all of that data the hard way.

Thankfully, my house has appreciated in value significantly and although it is nice to have a low mortgage, I could be making at least $1,000 per month if I was renting it out (rent avg. around the area vs my mortgage).

So here I am, having recently been laid off from a primary job (I have 2 full time tech jobs) and am not only SUPER glad I don't have that 3K a month mortgage to deal with (that said I am making the same from my one job now that I was when I lived there, it was only after I sold it that I picked up the second job but you'd be amazed how you get used to having a 30K a month gross W2 income, even with one job loss it still feels like you have none despite having a second...) and am living in a house that costs me less than 1K a month mortgage wise AND...that house that I sold has barely moved in value at all since I sold it.

My personal house has tremulously grown in value just in 4 years since I bought, which is how I'm able to take a line of equity in my primary residence to use it for investment purposes.

It also has free data and free sales comps.

This is a smallish town (pop 10k) but it is home too many large employers as well as Googles second largest data center in the world!

Data I get through Spokeo and Intellius is horrible.
