Currently I'm using a variety of Craigslist ads as well as Zillow, Trulia, and Hot Pads.

Sellers ask for either proof of funds or proof that the buyer can obtain financing because(1) earnest money is often - maybe most often - refundable for a variety of reasons (contingencies)(2) the seller doesn’t want to engage in legal action to obtain the earnest money should the buyer default (title in many states will only “release” earnest money when the opposing party agrees - if not it becomes a court issue)(3) the seller doesn’t want to tie up the property if the buyer can’t perform EVEN IF he would get the earnest money as consideration(4) the seller NEEDS the property to sell much more than he needs the earnest money - he may have a purchase contingent on the sale of the subject property, or numerous other reasons. (5) seller may be able to obtain a higher price by asking for less earnest money and better pre qualifying buyer than relying on the amount of earnest money to “qualify” the buyer. 

They offer a variety of underwriting sheets.

Not certain if they have mailed out the quantity I have at the variety I have however when they type responses they're typically right on.Happy house hunting

After all they aren't a fix all solution and frankly having a variety of touch tools is a better implementation of marketing dollars.

Sellers pay for this convenience all the time for an infinitely wide variety of reasons.
