what is the appreciation of the house?
You could pay down loan to get PMI removed, or refinance if value of house appreciates, and PMI would go away.
Have you modeled both situations in a spreadsheet?
There is a net worth solution- which gives you highest net worth quickly
There is a cash flow solution- which gives you highest free cash flow sooner
what is the goal?
retire earliest?
investment balance for a given age?
free up cash flow?
reduce risk?
reduce debt?
My goal is to reach financial independence. For me it isn't about necessarily retiring early. Rather it is about having the option to retire if I want to or perhaps choosing a part time or lower paying job that I enjoy more. That and to have an emergency fund that will protect me against unforeseen problems.
