I think fixing prices is illegal!but your points are valid and could force prices down,based on a fictitios availability
However I think it could be controlled by making it a condition of listing that when a unit is rented owners MUST remove it immediately upon rental and funds received for the rental or they are not permitted to EVER list again on the site.
You could easily add a column on the page to indicate rented or still available based on owners providing accurate updated information
You could also encourage owners to keep the info up to date by making the listing fee $100 with a refund of $50 when people idicate it is listed.No up to date indication/no refund .
Thanks Carl

OOPS ERROR,
Last line should read
'$100, with a refund of $50 when people indicate it is RENTED".

I have never had a problem renting my units. I would hate to be told how much to rent them for. I list for a fair price and have always removed my listing when rented.

Carl - I'm wondering when you'll post our rental on the database? We submitted the information and payment to you on 7/24.

Thank you very much for your time,
Cathy
