In your experience have you ever had a realtor give you a short end of the stick maybe by not being truthful about the property stats just to sell ect or normally are realtors straight forward bc they create win win situations of them selling making a commission and you buying making an investment ect? 

I assume it measured straight population growth which revolvles around jobs and construction I guess.

Perhaps @Dion DePaoli can provide some insights.The discount from the face value depends on many factors.  

The law says that no unlicensed entity can receive 'any' considerations due to the purchase/sale of real estate.That means gift cards, credit points, discounts, cash, etc at closing.Like @Dev Horn says if you pay a flat fee for each lead then that isn't a consideration for closing any transactions and it would be strictly lead generation.If somebody brought me a deal and I closed on it before paying them If I was fearful of paying them for it bc they were unlicensed then I think I would simply give them the option to have money out into a marketing campaign for them to manage.Like buying 1000 direct mail letters with their information on it bc that would be you putting money into marketing vs giving a consideration.

They are discounted and sold for cash so that the money can be used to gamble, buy drugs or alcohol.

How much discount off market value would we need to achieve to make this a viable deal?

I don't know anything about InfoUSA, but if they do what they say they do "well", their system should keep most of the emails from going straight to junk.  

But, straight up comp.s are still the best.

I'm buried in distressed properties that I'm selling at a huge discount... blah blah blah."  

Great area real close to dc with out the Dc price and get more home , the best way in that area is to get you one that needs some work so you can get it at discount do you a renovation and have some equality in it . look at you some signs in the area and see who is there and give them a call and tell them what you are looking for are drive by the area alot  and you may see a few for sale by owner by not many or go to your local REA and see if anyone is birddog that area and can call you if a deal come up  wish you luck  Amy
