In that case, here’s what I would do –

step 2: car payment done
step 3: bigger emergency fund to an amount you feel comfy at (not to exceed 3-6 months expenses)
next: back to step 2 for 27,000 house pay off
If still in paying off house stage when child hit 18–could always stop paying extra on house and help child, if wanted—or some extra to house, some extra to help child
Just my 2 ideas on the topic, everyone must do what is best for their personal situation.
