Does paying a vacant home's property tax give me title to it?

[Benjamin Herrmann]

My mother-in-law owns a rental property in Portland, OR 97236. There is a vacent property directly behind her's. I looked up the county tax records to find that they have not been paid in 3 years, making the total amount owed is $9,800. 

I have heard rumors that if you pay off the overdue property taxes the county will give you title. Is that true? If so, does the county give me a Quitclaim deed in exchange for the paid taxes?

We would like to buy the house and really could use some advise.

Thank you so much!
