how do you buy land from the city?

[Brian Wang]

Hi biggerpocket! 

i know a vancant lot in my neighbordood for at least couple years now. i never really pay much attention to it until today.  it between two houses.  but when i go online, the there is no info regarding to the house at all, no tax info, no owner info, all it has is its size and lot #. that's the first time i saw something like this. usually even vacant lots has owners. but this one does not.   my guess is to call the department of finance. what if the lot really belongs to the city. is there anyway to buy from besides waiting for an auction? 

Thanks :)
