Page 2 of your Loan Estimate breaks your closing costs into lettered sections, and Section A is the first one. It matters more than the rest, for two reasons: it is the money that goes to your lender, and it is the money that is not allowed to change.
Section A is titled Origination Charges. Everything in it is money paid to the lender or broker for making the loan. Typical lines:
Different lenders slice this up differently. One lender's single $1,850 origination fee is another's $600 underwriting plus $700 processing plus $550 application. The names are not standardized. The section total is what you compare.
Section B is Services You Cannot Shop For — the appraisal, credit report, flood determination, tax service. The lender picks the provider and you pay for it.
Section C is Services You Can Shop For — title insurance, settlement or closing fees, survey, pest inspection. Your lender gives you a written list of providers, and you are allowed to use someone else entirely.
The distinction that matters: Sections B and C are largely third-party costs passing through your lender. Section A is your lender's own revenue on the transaction. That is why it is the section with real room to move.
Federal rules sort closing costs into tolerance categories, and Section A sits in the strictest one — zero tolerance. The origination charges disclosed on your Loan Estimate cannot come in higher on your Closing Disclosure.
The one exception is a documented changed circumstance: you switch loan programs, your lock expires and you relock, something material about the file genuinely changes. The lender then issues a revised Loan Estimate and resets the baseline. What is not legitimate is Section A quietly growing between the two documents with no revised estimate in between.
The full breakdown of which fees can move and by how much — including the 10% cumulative group and the fees with no cap at all — is in Closing Costs and the Fees That Aren't Allowed to Change.
Line up the Section A totals from every Loan Estimate you have, side by side. Then read them together with the interest rate on page 1, because the two are directly linked — points in Section A are the price of the rate you were quoted.
A lender showing $9,400 in Section A at 6.25% and a lender showing $1,200 at 6.625% may be offering nearly the same deal in different clothes. Or one may be considerably better. You cannot tell from either number alone.
The one comparison that is always fair: ask every lender for a quote at zero points. That strips the rate buy-down out of the picture and shows you what each lender's actual pricing and fees look like underneath. Any lender can produce one, and it takes about a minute.
Section A is negotiable in a way Sections B and C mostly are not. Your lender does not control what the appraiser charges. It entirely controls its own underwriting and processing fees.
You have the most leverage before you lock, and more still if you hold a competing Loan Estimate. A lender that wants the loan can reduce or waive fees in Section A, or offer a lender credit that offsets them. It is a normal conversation and nobody will be offended by it.
One thing to be careful about: reducing Section A by taking a higher rate is not the same as reducing your cost. It is moving the cost from closing day into every payment for the next thirty years. Sometimes that is exactly the right trade. Know which one you are making.
