Buying a House, How To Check For Any Hidden or Unmentioned Debts?

Hi, advise please!

We're thinking of buying a house and there is apparently nothing wrong with the chanote (copy)
that we've seen. It's "clean" and there are no debts listed.

However, can I be sure that there aren't any house-related debts or hidden debts (not mentioned by the owner) that could result in the house being taken from us at a later date.

Examples could perhaps be banks or credit (card) companies that may want the seller to sign papers, using the house as collateral.

I'm guessing that any personal debts would follow the seller, but not affect the status of the house.

I don't know if ALL house-related debts are required to be specified on the chanote, or not.

At this point I don't think there are any problems, but it would be nice to be sure about things.

Thanks

Apologies if this is not in the correct forum.
