I haven't heard of gifting clubs but there may be some kind of down payment assistance program. Start calling around to brokers and lenders and see what is availble. Gifts general have to come from a family member not a third pary organization.
Google the county name and Affordable Housing and you may be able to find "bond" money to help you purchase a property. My client is closing on a nice house today in Tampa and has to bring only $36 to closing!
