Across the country, builders and developers have been offering home buying incentives including interest-rate reductions, prepaid homeowner association fees, cable TV and Internet access, appliances, “use-as-you-choose” spending certificates, price reductions and help with closing costs.

One home builder recently offered visitors to its new developments the chance to win a diamond ring valued at $4,500. Other reports include builders offering buyers enticements such as new flat screen televisions, one year of lawn care service or a “sign today” promotion of free upgrades.
