The sale of a posh Presidio streets and its surrounding sidewalks is legal even though the local tax assessor had been sending tax bills to the wrong address for years, a new report from tax authorities says. Investors Tina Lam and Michael Cheng, bought the street for $90,000 in 2015 at auction, Cheng and Lam were able to buy the street after its residents didn't pay a $14 annual tax for 30 years, an oversight that was reportedly due to the city sending the tax bill to an incorrect address.
