Help explain this House foreclosures

Could you explain to me what happens to the money you've already paid once your house get foreclosed on?

How would you express these sentences grammatically?
1 When you don't pay your mortgage, your house gets foreclosed on and you lose the money you've paid on the house. or do you get the money you've paid so far back?
2 Would I lose the $100000 that I paid on the house when the bank foreclosed on my house.


Is it grammatical to say " you lose the money you've paid on the house"?

Thank you
