in terms of incentives, why limit it just to cash? we have all kinds of other ways to motivate people. perhaps a home purchase could come with one “get out of jail free” card? Or you would simply be the subject of an honorary dinner where people would come and sign your praises, along with other home purchasers/ These sorts of non-cash incentives might be just as motivational for people to make purchasing decisions and might cost less. Get creative people, money isn’t everyhing!
