I closed on a house last week from a lead that Houses for Sale provided. There was not much action for the first year or so, but then the leads started coming in. I knew they were a startup and if they were able to deliver the ROI would be worth it. Considering that I have less than $120 invested over the entire time with them this has become the single best lead generation tool when you look at the ROI on the spreadsheet compared to other services. Plus, its an exclusive zip code (I own two). For me Houses for Sale has delivered.
