I was rated 100% for hearing loss in one ear. Does this qualify as service connection disability that waives VA home loan origination fee for refinancing of my current VA loan?
I can't be sure as a 100% permanent rating for one ear is a bit unusual. If I had to guess I'd say yes, a 100% rating should make you eligible. You'll have paperwork and VA contact points for questions regarding your VA COE as your loan progresses and then is a good time to ask that and other questions.
During my last (and final!) home purchase I used a broker to find my financing and that was a real plus as they took care of a lot of details I'd have missed. The broker was methodical, crossed t's and dotted i's and put it all together in a way I couldn't have when presented to banks for a bid. That made the difference of almost 1/2 point in the rate and that seems even more important today.
Don't forget that in many states a vet with a 100% rating is exempt from state property taxes and sometimes the path to that benefit via the state can be convoluted...but worth the bother.
All the usual rules for taking out a loan in the first place are there when we refi the original note. If you've been rated at 100% since you originated the loan in the first place you'll probably have more hoops to jump through to maximize the benefit. Do shop around though...rates are through the roof today!
