Edit 8/13 3:30pm: Thank you everyone for the helpful advice so far. The lender behind Options A & B contacted me and lobbied for himself, saying there is a $1000 credit towards closing which legally can't appear on the GFE and TIL, but which will be reflected at close. So, cash-to-close numbers have been updated. Also - and this is important - the 15-year loans are conventional, NOT FHA. Sorry for the confusion - new FHA rules will not apply. Lender states I can simply call up customer service and drop PMI when my loan reaches 78% LTV.
I have a feeling the decision now will be more affected by how/quickly much we intend to prepay. For Options A & B, LTV is right now around 91.5% ($339000) and I need to get to 78% ($288,600). So, a little over $50k.
Lender also stated if I prepay more than $5k principal in a 12-month rolling period, I can recapitalize (or something). Any info here is appreciated. I wanted details in print but he was unable to provide them, saying it was simply a part of their "overlays". Does any of this sound familiar? I have asked him for details via Email - especially how this could benefit me.
All numbers below have been updated.
