Ca Mortgage Rates

Mortgage Loan in CA Please Help?
Our loan officer was not completely honest with us. It started out with a problem and turned into a nightmare. To do a long story short we were pre-approved for a 5.8% loan on a house that was $ 300,000. Documents were signed and contingencies were released. A week and a half later loan officer had us return to sign more docs. He said nothing has changed just need more signatures. He did not give us a copy of the paper work he said that he would drop the signed docs in the mail. After weeks of mislead and 3 weeks late to close escrow, we find that the loan officer we were dealing with is not FHA approved, and he passed us to another loan officer. We got docs back and now they are at 6.5%. We've been so mislead. My question is, when we have all the paperwork from this bank if we shop around and find a better price, how long does it usually take to get approved? We were already approved with this bank and FHA. PLEASE HELP.
Go with a reputable mortgage bank, they accept you (guarantee) and wire money (fund) at closing.
