Over due taxes on property

[Elizabeth Mckinnon]

My brother has been living in an apartment complex since 2005. The apartment has 11 units and only two units is being rented. My brother Mail  his rent payment of every month. Yesterday the sheriff  posted a tax bill which have not been paid in the last three years on his door.  My question is if we pay the past due taxes how can we get our money back if the owner shows up.
