As of December 23, 2009 there are only 3 properties for sale in the greater South Tahoe area. They are all condos near the 'Y' in South Lake Tahoe and are close to Kirkwood, Sierra and Heavenly ski resorts. All three are 2 bedroom 1 bath , 2 are 840 and the other is 870 square feet. As the Real Estate market changes so will pricing and inventory, so it would be worthwile to sign up for a 'Listing Notification' to notify you if properties fall into your personal preferences. If you need some assistance with that I would be glad to help you with that.
Good Luck with your search,
I own a cabin in Tahoe and I'm also a Realtor. I know the area well. Did you decide on what you want to do? Have you done some research? What sites are you using to find homes? ]
Let me know if you need any assistance.
