Foreclosure Unpaid Balance + Fees

[Paul Munley]

I tried to find a specific answer to this question but was unable to find it. On a foreclosed home what is the importance of knowing the unpaid balance and fees? I know that any unpaid taxes on the home are owed by the person who purchased it. Are there any other important fees to take into account as well such as unpaid HOA fees? And what is the importance of knowing the unpaid balance on the property because you are going to end up paying just what you purchased the property for correct? I'm sorry if these are newbie questions by the way, just trying to learn as much as possible.

Thanks!
