Your parents can "authorize" you on the account so you can talk to the bank and make payments.

Plus, I like my little remaining time and aren't looking to get into a giant time-suck. 

Other than that, without re-doing it in my own analysis, on the surface it looks fine, especially because you're down payment is larger and loan is smaller.What aren't we seeing in the spreadsheet?

Time for a divorce and to marry up to someone who knows what they are doing.However, the Fannie and Freddie guideline for a 4-unit cash out refi is 70% LTV max, so that part is correct.No need for commercial if you're good with a $490K loan amount if it appraises for $700K.And don't pay points unless you aren't going to sell or refinance again for at least 6-7 years or more.And find a new loan officer, for the love of all things holy.
