The Truth in Lending disclosure document (i.e. good faith estimate) is one of the first things you should have gotten from your broker, especially if they’ve already ‘found’ you a loan product.
You are 3 weeks into the lending process and a week from closing escrow and your broker hasn’t even disclosed the terms of the loan? Has she even locked your rate?
I’d fire her immediately and consider contacting the attorney general..but that’s just me. No house is worth getting screwed over for. It could end up costing you alot of money beyond the broker fees.
