I have done both - rented just points and rented a certain time.
my problem was I wanted to use that time - but my brother cancelled on me in Oct - it was for a Thanksgiving BWV standard view. I decided to rent it if I could do it quickly 14 days. the first time I posted nothing - so I moved that post up at week later - got a bunch of takers.
I don't go with the first one. Try to offer less money then wanted a 1-bedroom instead of the studio I had. The next one was much nicer a lady and I would certainly rent to her anytime!!!
with the points I had even more problems. I listed certain times that I would rent it - Sept - Nov. Didn't want to deal with Easter or Christmas time when the point cost are high. People were constantly wanted me to try for summer or spring break. I also said studios only. Well one person wanted a 2 or 3 bedroom for 2 weeks in January.
People don't read your ads!!!
so just saying points is probably your best method. I like little contracts so if someone cancels on me it is not a problem.
besides my brother I just had one cancelation. It was for the first week in Dec and I could rerent it so that one wasn't even a problem.
don't ask about my brother he has cost me a fortune over the years cancelling a month or less before we leave.....
