Chida,
In addition to the additional cost that is passed on to future consumers due to breaking rate locks, there is another effect that is rarely noticed or mentioned. Why do you think some originators will lie to you regarding the rate and fee structure that they are able to offer you? Maybe they see your transaction the same way; a one time deal. What do they have to lose by telling you that your rate is lower than they can actually deliver today? If they lie, they don't have to worry about you moving on to another lender if rates remain the same or if they go up. If rates drop, they still can lie all the way to the table. I mean, why would you go through the entire process again only to get the same deal; after all, you will only deal with this person once.
Now do you see why there are some originators who decide to lie to their customers? Do you see how your actions when multiplied can entice an originator to stop acting ethically and start by embellishing a little? Many customers despise those originators but they perpetuate the problem by continuing to shop even after they have agreed to a rate lock. Why should an originator be loyal to you if you are not loyal to them?
I see things very differently. Maybe you and I will only have one transaction together. Maybe we won't even do any business with each other at all, but I have closed many loans by receiving referrals to other people that would like to work with someone that they can trust. I know that by being honest, I can earn more business over time... but some originators, like some people in any other arena, are willing to take shortcuts to make money today by whatever means necessary.
Chida:... to stay loyal to a lender whom we'll never every say even a hello in our life again?
I truly hope that my customers will call or email me and just say hello; I enjoy hearing from them and I hope that they enjoy hearing from me as well.
Chida:So, in theory, one would like to lock in to something that suits them & expect the lender to give advantage of the situation if the rates go low.
That is great in theory, but poor in practice. Most of the lenders that do not offer a float down or renegotiation policy have the lowest rates on any given day. Those lenders that offer a rate slightly higher today, may offer you the ability to float down tomorrow. As they say, "He who has the gold, makes the rules." If you want or need the money that the bank is offering, you have to play by the rules that they have set. Remember, borrowing money is a privilage, not a right.
