Why would banks let property go to delinquent tax sale?

[Dante Covington]

Hello everyone, my name is Dante. I recently went to a few delinquent tax sales to purchase a few properties and in my research of the properties I noticed that some of them were owned by banks or investment companies. My question is why would these banks let the homes go to tax foreclosure, they surely have the money to pay a couple thousand in taxes. Can someone help out with why this happens? And should invest in these.
