I'll say it again... Ask for a relock at no charge. If they won't, then ask what the charge would be. It could be a lousy 1/4 percent and that is peanuts compared to what you've invested.
It doesn't hurt to ask.
Repeat... It doesn't hurt to ask.
Obviously I'm the only broker here who is looking at it from the view of the customer. I wouldn't care one lick what the lender's costs are or if the lender drops the broker, I'd care about my own personal finances. The lender will make plenty of money from your finance charges, that's why they lend money. Play hardball and see where the chips drop.
Customers do it to me every day and I do it for the ones who stay with me. This is not a monopoly game, this is years of your money in payments. I don't work for the lender, I work for my client. If I wanted to work for a lender, I'd sign up at a bank. Make your broker earn his money and you just might get lucky. No matter what happens, don't feel bad for everyone else. You're dealing with sharks and you need to keep your teeth bared.
I'm not saying your going to get it, but I'm saying fight for it and don't go down without being knocked out.
