You are not giving us enough information....is the property a time-share, in a subdivision, new or used mobile home affixed to property, are you the seller that has hired an agent, listing agent, or is this home FSBO?
If you are simply selling the home along with the property as part of the sale itself and the furnishings are included and will go to the buyer, this does not appear to be a violation of law. Make sure you adequately define the items to be included in the sale and make your conditions known up front so the buyers can make you an offer including all the items you wish to include in the sale.
If you are giving the gifts to the selling agent, lender, escrow, title etc....then you may step into RESPA and DRE violation territory.
Please check the following:
B & P Code 17537.1. "Conditions for receiving gifts and prizes."
B & P Code 10131.7 "Mobile Home advertising criteria."
B & P Code 10140 "False advertising"
RE Regs 2799.1 "Subdivision advertising criteria"
RE Regs 2800(d)(2) "Notification of material change."
RE Regs 2811 "Time share advertising criteria."
