If you feel like your broker isn’t answering all of your questions to your satifaction, then you should probably find another broker. I’ve been in your siuation, and there’s nothing worse than a broker that takes the wrong tone, or doesn’t take the time to understand and answer your questions.
As a side note- HUD-1, GFE’s and all real estate transaction documents for that matter, are intentionally deceptive. Unless you deal with them all of the time, it takes a minute to understand what you’re looking at. That’s why, in part, a good broker can be an asset.
