Well it is good to know there is a five year limit. What happens after that? Are the debts THEN discharged?
IF, very important IF, you have your Ch 13 plan approved, you essentially buy back the non exempt assets of your ch 13 extate. If you live in a state with no homestead exemption it means you WILL loose your home.
The final discharge means all debts are satisfied. It usually means the unsecured creditors are screwed with a few cents total.
If you can not finish in five years, you may not qualify for a ch 13. (ie back child support arears, mortgage arears)
