According to the SOCALMLS, the average Days on Market for Single Family Homes is 126 days (for all sales since 9/1/11) in the Belmont Shore/Naples/Peninsula areas. For condos it's 111 days. As you would expect, in general, the higher priced homes take longer to sell.
I'd be glad to go over more specific statistics if you'd like. Feel free to give me a call at (562) 2089-9818, or email at Peter@TheREALPete.com. Thanks!
