Hidden charges and overriding interests

1. Are there any such hidden charges in your system? If so, please list them, and explain how a buyer can discover them. Explain if there is any simple way that the property can be freed from them.

2. Do any of these, or any other similar matters, have priority over a mortgage, where the lender was acting in good faith and was unaware of them? Explain if there is any simple way that the property can be freed from them.
