I sense a problem here. If you are willing to rent your points to a relative, decide if you want to treat this as a business situation or a helping family situation. $10 pp is the going rate and if you're just trying to use some points at the same time you help them out, $6-8 pp is a fair price. I'm assuming you already quoted them a price and they're balking at it due to the recollection of one special last year off season at the bottom of the 9/11 aftermath. If this is the case, you're likely much better off not even renting to them as you're asking for trouble.
Specific to your question, I doubt they saw a 1 BR for that price but it's possible. Even if they did I doubt it would have been summer or weekend for that low. The price (whatever it was) would have been plus 11% tax but would have included daily maid service. If they're looking at a long weekend or similar, do them a favor and suggest they do cash and not rent points.
Proceed with caution if I'm picking up the right vibes. I feel you have the potential for a situation where you feel you're helping them out and they feel you're ripping them off.
