What Is a Good Faith Estimate? Mortgage and Healthcare

A Good Faith Estimate is a written breakdown of what a service will likely cost you before you agree to it. In mortgage lending, the Good Faith Estimate has been replaced for most home loans by a standardized document called the Loan Estimate, which your lender must deliver within three business days of your application. In healthcare, the No Surprises Act requires providers to give uninsured and self-pay patients a written cost projection before scheduled care. Both versions exist for the same reason: so you see real numbers before you owe real money, with legal remedies if the final bill jumps well beyond what you were told.

The Mortgage Version: The Loan Estimate

For most home loans, the traditional Good Faith Estimate has been folded into the Loan Estimate, a three-page form created under the TILA-RESPA Integrated Disclosure rule. It combines what used to be two separate disclosures into one document covering loan terms, projected monthly payments, and estimated closing costs.

Your lender must deliver the Loan Estimate no later than three business days after receiving your application.¹ “Application” has a specific meaning here: you’ve handed over six pieces of information — your name, income, Social Security number, the property address, an estimate of the property’s value, and the loan amount you want.² Once you provide those six items, the clock starts. A lender cannot charge you anything beyond a credit report fee before delivering the estimate, so you can gather Loan Estimates from several lenders without commitment.

The Loan Estimate shows your interest rate and whether it can change, the monthly principal and interest payment, estimated property taxes and insurance that may be escrowed, and a line-by-line list of closing costs including appraisal fees, title insurance, and lender origination charges. It is designed to be laid next to estimates from other lenders and compared directly. A few loan types stay outside the TRID rule and may still use the older Good Faith Estimate format, including reverse mortgages.¹

When a Lender Can Legitimately Change the Numbers

A Loan Estimate is not a guaranteed price. Your lender can issue a revised Loan Estimate if genuinely new information surfaces. Common triggers include the home appraising below the purchase price, the lender being unable to verify overtime or bonus income you claimed, you changing the loan type or down payment amount, or you requesting a rate lock after the initial estimate was issued.³ What a lender cannot do is quote you an artificially low estimate to win your business and then revise upward without a legitimate reason. That is illegal.

Tolerance Rules: How Much Fees Can Move

Federal rules sort every fee on your Loan Estimate into one of three tolerance categories, and the category tells you how much price risk you actually carry.

Zero tolerance applies to fees paid to the lender and to fees for third-party services where the lender did not let you shop for the provider. If the origination fee on your Loan Estimate is $1,200, you owe $1,200 at closing.⁴

A ten-percent cumulative tolerance covers recording fees and third-party charges when the lender gave you a written list of approved providers. Individual fees in this bucket can move, but their combined total cannot rise more than 10% above the original disclosure, and no fee in this category can be paid to the lender or a lender affiliate.⁴

Some costs have no tolerance limit because they depend on factors no one controls at the time of the estimate: prepaid interest, property insurance premiums, and amounts placed into escrow. The lender must still base the estimate on the best information available, but there is no cap on how much the final number can exceed it.⁴

When fees in the zero or ten-percent categories exceed the allowed limits, the lender must “cure” the violation by crediting you the difference, usually as a lender credit on the Closing Disclosure with a statement explaining the offset.¹ This is the payoff of comparing your Loan Estimate against your Closing Disclosure line by line before you sign.

The Healthcare Version: Good Faith Estimates Under the No Surprises Act

Under the No Surprises Act, every healthcare provider and facility must give a written cost estimate to patients who are uninsured or who choose to self-pay rather than run a service through insurance.⁵ “Uninsured” here also covers people enrolled in short-term limited-duration plans or health care sharing ministries who don’t carry a qualifying group or individual health plan.⁶

You don’t have to file paperwork to get one. Under federal rules, even asking a provider about the cost of a service counts as a request for a Good Faith Estimate. A phone call or an in-person question is enough to trigger the obligation.⁷ The provider can respond verbally on the spot but must still follow up with a written estimate.

How Quickly You Must Receive It

The timing depends on when the service is scheduled:

If the service is scheduled at least 10 business days out, the estimate is due within three business days of scheduling.
If the service is scheduled 3 to 9 business days out, the estimate is due within one business day of scheduling.
If you’re just asking about cost without scheduling anything, the estimate is due within three business days of your request.⁷

What the Estimate Must Include

A healthcare Good Faith Estimate isn’t a rough ballpark. It must list every item and service the provider reasonably expects you’ll need for the scheduled care, broken out by each provider or facility involved. If your surgery requires an anesthesiologist, lab work, and imaging from separate providers, each should appear with its own expected charges. The document must also include diagnosis codes, service codes, and identifying information for every listed provider or facility, along with a disclaimer that the figures are estimates and additional services may be recommended later.⁷

What’s Not Covered

The requirement doesn’t reach emergency or walk-in services, since those aren’t scheduled in advance. If you go to an emergency room or walk into an urgent care clinic, no advance estimate is required. The rule also currently applies only to uninsured and self-pay patients. The No Surprises Act contemplates a future “advanced explanation of benefits” process for insured patients, but federal agencies have deferred enforcement pending further rulemaking, and no final rule has been issued.⁸

What Happens If a Healthcare Bill Exceeds the Estimate

If any single provider or facility on your final bill charges $400 or more above that provider’s estimated charges on the Good Faith Estimate, you can initiate the Patient-Provider Dispute Resolution process.⁹ The $400 threshold is measured separately for each provider or facility on the estimate, not as a total across all of them.

You have 120 calendar days from the date you receive the initial bill to file. You start by submitting an initiation notice to HHS through the federal dispute resolution portal, electronically, or by mail, and HHS assigns a Selected Dispute Resolution entity to review the case.⁹ An administrative fee applies; CMS set it at $25 when the program launched and indicated the amount may be adjusted later.¹⁰ The reviewer weighs whether the provider has shown the difference reflects medically necessary services and whether the higher charges stem from circumstances the provider couldn’t reasonably have anticipated when the estimate was issued. The determination is generally binding on both sides.¹¹

Getting the Most Out of Your Estimate

Receiving the estimate is only half of it. What you do with it matters more.

If you’re shopping for a mortgage, gather Loan Estimates from at least three lenders using the same loan type and down payment. That makes the comparison apples to apples. Focus on the “Loan Costs” section rather than the total closing costs figure, since prepaid items like homeowner’s insurance and property taxes will be roughly the same no matter which lender you pick. When your Closing Disclosure arrives at least three business days before closing, put it next to your Loan Estimate and check every line. Any fee that increased without a documented changed circumstance is worth questioning before you sign.

If you’re a patient, keep every Good Faith Estimate you receive. When you’re scheduling a procedure and the estimate seems to cover only the surgeon, ask specifically about anesthesia, lab work, facility fees, and imaging. Those co-provider charges are supposed to be on the estimate, but they sometimes get left off. If your final bill comes in higher than expected, compare it line by line against the estimate before paying. The $400-per-provider threshold that opens the door to a dispute is measured against the original document, so keeping the paperwork is what makes the protection real.
