You can always
Leave at any timeYou're never required to stay or to buy.
Say you need a lawyer to review it"We don't sign contracts until our lawyer has reviewed them."
Get every promise in writingIf it isn't in the contract, it may not count. The FTC says you have the right to get all promises in writing.
Take the paperwork to reviewAsk to take it with you. If they won't let you, that tells you something.
Ask for the full cost in writingPrice, financing, interest and yearly fees, not just the monthly payment.
Reps can't
Lie about the timeshare or what it costsFalse statements in a sale are against the law everywhere.
Sell it as an investment that will grow in valueMany states ban claims about investment, resale or rental value, or predicting the value will go up. The FTC says a timeshare's value is in using it, not as an investment.
Hide the conditions on your free giftSeveral states require the gift's conditions in writing.
Reps can, but you don't have to go along
Say the price is "only good today"Legal in most places. A real offer will still be there tomorrow.
Bring in another managerYour answer can stay the same.
Keep lowering the monthly paymentAsk for the total price, financing cost and yearly fees in writing instead.
Offer a bonus if you sign nowBonuses are part of the pitch. They don't change the cost of owning it.
