Sheriff sale for HOA with existing mortgage balance

[Shelby LeBlanc]

I have found a SFR going to be offered at a sheriff sale for the delinquent HOA fees ($5488). There is also an existing mortgage with a balance of approx $250K.
I don't understand how this works. If am the high bidder of , let's say, $25K, what happens to the mortgage balance? I don't know if the mortgage payments are up to date. Is there a possibility the mortgage will reimburse me and add it to the mortgage balance? Any insight to this is great appreciated. Houston Texas area is the location.
