internet tax auction. it s very rare in san francisco that what actually goes on the auction block isa real property of value. reporter: d you ow which street you were buying when you bought it? i had some idea, but i didn t know exactly the details. reporter: the home owners are calling on the city to negate the deal. the sales are absolutely valid. reporter: can the board of supervisors negate it? that s a question for the board of supervisors. i m pretty comfortable that we ll prevail. reporter: in the meantime, what do you do with a street? are you thinking about charging for parking? we can talk about that. certainly because they are now parking on my land. reporter: i m sure they ll be talking a lot in months to come. the home owner s association attorney sent us a statement saying the couple appears to be opportunistic and they re hoping the error can be corrected. that remains to be seen. at city hall, it sounds like a deal is a deal and a sale
