I just checked all the current listings for homes, condos, and multi units for sale here in Venice and there doesn't seem to be any record of a property on Rialto for sale. No listing on Rialto as been withdrawn, cancelled, expired, leasd, or closed escrow since Nov. 1 either so I'm not sure what this one is about. I can check the tax records and contact the owner for you if you'd like.
There are 57 other single-family homes, 27 condos, lofts and townhomes, and 21 income properties currently for sale here. I'll be glad to send you these lists or I can email you selected listings and perhaps discuss other options available if you want to let me know what your preferences are. You'll also find all the properties for sale in Venice and L.A.'s other beach cities posted on my website.
Best of Luck.
