You're not going to like my answer . . . and I'm viewing it after you've made the updates.
Your site stinks. It's a series of squeeze pages with no useful information. Oh, sure, you promise a lot. Page after page promises information. Sometimes special reports. Sometimes just information. But you consistently don't deliver. Each is just a teaser to get the person to provide his/her contact information.
How about some information about yourself? About the local schools? Or the local community? Or, hey, since your big selling point is a cash-back rebate, why not actually explain that? But, no, you're forcing potential customers to provide their valuable information to get what (from your home page) details on what you consider to be your main selling point.
And some of that's just plain odd. You have a tab for "Affiliates." That terminology has a different definition in web marketing. It's not mortgage brokers, home warranty companies, etc. Still, if I click on "Mortgage Broker" or "Home Warranty Company" on a site, I expect a name, or list of names. Instead, you're asking me to fill out information on a squeeze page to get a list (or is it just one) of recommended mortgage brokers, home warranty companies, etc.
I agree with some of the other comments (such as Debbie's) that the site is just downright ugly. And I also agree with Jerry that you don't seem to be interested in serving people of various backgrounds, races, etc. In fact, with the exception of your photo, I only found two (shots 1 and 3 on your home page) with people at all. Shot 1 might be OK to represent Hispanics. Shot 3 is so small I can't tell. But here's a marketing tip: People want to be able to relate to others like themselves. Other than yourself, the kids in 1 and the couple in 3, you have no shots of people.
So: No people. No useful information. An unattractive site. A succession of squeeze pages. My guess is that someone persuaded you that that site template works wonders . . . that it's been tested and refined . . . that it's web optimized (see Stephen's comments below) . . . that it's the best thing since sliced bread. All you're really offering is a rebate on your commission with no details supplied.
Find another template. Offer some useful information. Put yourself in the place of prospective sellers and buyers and ask yourself: What would they want? Then give it to them.
Hope that helps.
