Since DW teacher’s salary is less than 1/4th of my salary so we have never considered her being working. All our budgets have been made using my income alone. So that is a net saving for us even though it is not too big.
I think we seems to be in same boat. Paying off mortgage may lessen our AMT liability too.
Our situation differs in only one way. DW working or not doesn’t make any difference to our financials or FA from MIT but loss of my salary will make a huge difference both on our financials as well as FA from MIT.</p>
