Your lender quoted $8,200 in closing costs when you applied, but the number on the closing table reads $9,600. Whether you actually owe that extra $1,400 depends on something most buyers never learn: which individual lines moved. Under federal law, some fees are locked to the penny from the first quote, some can drift only within a shared 10 percent band, and the rest can move freely. The same law bans the kickbacks that used to inflate those fees behind your back and caps how much extra cash your servicer can park in your escrow account every month. That law is the Real Estate Settlement Procedures Act — RESPA — and this guide explains every protection it gives you, in the order you will meet them.
What RESPA Is and Which Loans It Covers
Congress passed RESPA in 1975 to attack two problems at once: homebuyers arriving at closing with no idea what they would owe, and an ecosystem of referral fees and markups that inflated settlement costs. Today the statute is implemented by Regulation X and enforced by the Consumer Financial Protection Bureau (CFPB).
RESPA covers most loans secured by one-to-four-family residential property: purchase mortgages, refinances, assumptions, property-improvement loans, and home equity lines of credit. It does not cover loans for business, commercial, or agricultural purposes, so an investor financing an apartment building under a commercial loan is outside its protections even though the collateral is real estate. If you are buying or refinancing a home you live in, you are almost certainly covered.
Three pillars carry most of the law's practical weight for a buyer: standardized disclosures with enforceable accuracy limits, bans on kickbacks and unearned fees, and quantitative caps on escrow accounts. Mortgage servicing rules — error resolution, force-placed insurance limits — form a fourth pillar you meet after closing.
Pillar 1: The Two Disclosures You Must Receive
Since the 2015 Know Before You Owe rule merged the old RESPA and Truth in Lending forms, two standardized documents bracket your transaction.
The Loan Estimate: Your Shopping Document
Within three business days of receiving your application — your name, income, Social Security number, property address, estimated value, and loan amount — the lender must deliver a three-page Loan Estimate. Because every lender uses the identical form, the Loan Estimate is your comparison-shopping tool: the loan terms table, projected payments, and closing-cost itemization line up box for box across competing offers.
Two details matter more than the headline rate. First, page one states whether the loan has features that can raise your cost later, such as a prepayment penalty or a balloon payment. Second, the "Services You Can Shop For" section lists settlement services — pest inspection, survey, title search — where you may choose your own provider rather than accepting the lender's default. Shopping those lines is one of the few things entirely within your control that lowers your cash to close.
The Closing Disclosure: Your Verification Document
At least three business days before consummation, the lender must deliver the five-page Closing Disclosure showing your final terms and costs. A general seven-business-day waiting period also runs from delivery of the Loan Estimate to closing, so the fastest possible timeline from application to closing is already over a week by law.
Your job with the Closing Disclosure is a line-by-line comparison against the Loan Estimate, not a glance at the bottom line. Page three carries a convenient "Calculating Cash to Close" table that flags which totals changed, but the legal question — which changes you must accept and which the lender must absorb — is answered by the tolerance rules below.
Only three changes force a brand-new three-business-day waiting period: the annual percentage rate rises beyond a small threshold, the loan product itself changes, or a prepayment penalty is added. Lesser changes, like a mistyped name or a seller credit adjustment, can be corrected on an updated disclosure without restarting the clock.
The Tolerance Rules: Which Fee Increases Are Legal
This is the part of RESPA with direct dollar consequences. Every fee on page two of the Loan Estimate falls into one of three tolerance buckets, and the bucket decides whether an increase at closing is your problem or your lender's.
Zero tolerance: locked to the penny
Fees paid to the lender or mortgage broker, fees paid to an affiliate of either, fees for third-party services the lender did not let you shop for, and government transfer taxes cannot increase at all. If your lender's origination charge was quoted at $1,200, it must still be $1,200 on the Closing Disclosure. The narrow exception is a valid changed circumstance — you requested the change, new information about you emerged, or an event outside anyone's control intervened — documented on a revised Loan Estimate delivered within three business days of learning of it.
10 percent cumulative tolerance: a shared band
Recording fees plus charges for third-party services you were allowed to shop for, where you picked a provider from the lender's written list, are lumped together: their sum may exceed the estimate by at most 10 percent. Note the aggregation — one fee rising 15 percent is fine if another came in low enough to keep the total within the band. If you shopped independently and chose a provider that was not on the lender's list, those charges move to the unlimited bucket instead.
No tolerance limit: best available information
Prepaid interest, property insurance premiums, amounts placed in escrow, and charges from providers you chose entirely on your own need only have been disclosed using the best information reasonably available. These can move without legal consequence, which is why your cash to close can still shift even when every capped fee holds.
The cure: lenders pay for their own misses
When a capped fee exceeds its tolerance, the lender must refund the excess to you within 60 days after consummation — the industry calls this a tolerance cure. You do not have to sue or file a complaint to trigger it; the obligation is automatic. But cures only happen if someone notices, which is the practical reason to keep your Loan Estimate and compare it against your Closing Disclosure before you sign.
Pillar 2: The Kickback and Unearned-Fee Bans
Section 8 of RESPA makes it illegal to give or accept anything of value in exchange for referring settlement-service business. Your lender cannot pay a real estate agent for steering buyers to its loan desk, a title company cannot pay a builder per referral, and a broker cannot collect a fee for directing you to an affiliated mortgage company. The ban runs in both directions — paying and receiving — and carries treble damages, meaning a successful plaintiff recovers three times the charge paid for the tainted service.
The same section bans unearned fees: no one may charge you for a settlement service that was not actually performed, or split a fee with someone who did no work beyond the referral. This is the provision behind enforcement actions against marked-up credit reports, duplicative processing fees, and "review" charges with no reviewer behind them.
Two related rules close common loopholes:
- Affiliated business arrangements. A lender or broker that owns part of a title company or other settlement provider may still refer you there, but only under three conditions: you receive a written disclosure of the relationship and an estimate of the affiliate's charges, you are not required to use the affiliate, and the only thing of value flowing back is a legitimate return on the ownership interest. A referral fee dressed up as a dividend fails the third test.
- Seller-required title insurance. Section 9 bars the seller from conditioning the sale on your buying title insurance from a particular company. Required use of an affiliated provider as a condition of the deal is the same violation wearing different clothes.
The statute of limitations for kickback and required-use claims is one year from the violation, so a suspicious charge discovered on an old Closing Disclosure may already be time-barred. Review the document while the ink is fresh.
Pillar 3: The Escrow Cushion Cap
If your mortgage includes an escrow account for property taxes and homeowners insurance, RESPA's escrow rules — implemented at Regulation X section 1024.17 — put a hard ceiling on how much of your money the servicer can hold.
The two-month maximum
Your servicer must compute escrow using aggregate accounting: it projects every deposit and disbursement over the coming year as a single running balance, finds the month the balance runs lowest, and sets your monthly payment so that low point stays at or above zero. On top of that zero-floor projection, it may add a cushion against tax hikes or premium increases — but the cushion cannot exceed one-sixth of the year's total estimated disbursements, roughly two months of escrow payments. A servicer holding the equivalent of four or five months "just in case" is violating the cap, no matter how it labels the surplus.
The annual accounting you should actually read
Once a year the servicer must run a fresh escrow analysis and send you the statement within 30 days. Three outcomes are possible:
- Surplus. If the analysis shows extra funds beyond the allowed cushion and the surplus is $50 or more, the servicer must refund it within 30 days. Smaller surpluses may be credited against future payments.
- Shortage. If disbursements outran deposits — usually because taxes or premiums rose — the servicer must let you repay the shortfall over at least 12 months rather than demanding a lump sum.
- Deficiency. If the account already went negative, similar extended-repayment protections apply.
Escrow analyses are also where servicer errors surface: a tax bill paid twice, a premium for a policy you cancelled, a disbursement posted to the wrong loan. Open the statement, check each disbursement against your own records, and dispute anything you cannot reconcile — which brings us to the servicing rules.
Pillar 4: Servicing Rights After Closing
Regulation X gives you structured ways to force your servicer to fix mistakes. If you send a written notice of error, the servicer must acknowledge it within five business days and resolve it — correct the account or explain in writing why it believes no error occurred — generally within 30 business days. A separate information-request procedure works on a similar clock. Keep making your regular payments while a dispute is pending; the error process does not pause your obligation.
Two more servicing protections are worth knowing. Servicers must credit your payment the day they receive it, so a "processing delay" that manufactures a late fee is a violation. And force-placed insurance — a policy the servicer buys when it believes your coverage lapsed — requires advance notices to you and must be cancelled with a refund of overlapping premiums once you show proof of your own coverage.
Servicing violations carry a three-year statute of limitations and allow actual damages plus, for a pattern or practice of noncompliance, additional damages up to $2,000. Complaints to the CFPB are free to file and routinely produce servicer responses within weeks.
Tracking Your Mortgage and Escrow in Your Own Books
Your servicer keeps its books; RESPA's escrow disputes go much better when you keep yours. A plain-text ledger lets you split every mortgage payment into its economic pieces — interest expense, principal reduction, and escrow deposits — so the annual escrow analysis becomes something you verify rather than something you trust. The Beancount documentation covers the transaction syntax used below.
2026-10-01 * "First National Bank" "October mortgage payment"
Expenses:Home:Mortgage-Interest 1,180.00 USD
Liabilities:US:FirstNational:Mortgage -720.00 USD
Assets:US:FirstNational:Escrow 740.00 USD
Assets:US:Checking -2,660.00 USD
2026-11-15 * "County Treasurer" "Property tax paid from escrow"
Expenses:Home:Property-Tax 4,100.00 USD
Assets:US:FirstNational:Escrow -4,100.00 USDWith the escrow leg of each payment accumulating in its own account, you can compare your running Assets:US:FirstNational:Escrow balance against the servicer's projection month by month. A growing gap between your ledger and their statement is the earliest signal of a misapplied disbursement or an over-collected cushion. Recording the semiannual tax bill and the annual insurance premium as transfers out of escrow, as above, also keeps your true housing expenses visible: principal paydown is not spending, escrow deposits are not yet spending, and only the actual tax and premium payments hit your expense accounts. If you like charts with your verification, Fava plots each account's balance over time, which makes a cushion creeping past the two-month legal maximum show up as a line drifting above where the math says it should sit.
Your Closing-Table Checklist
Bring three things to every closing: the most recent Loan Estimate, a list of which fees sit in which tolerance bucket, and the willingness to slow the signing down. Compare the Closing Disclosure line by line, confirm any increase sits in a bucket that allows it, check that no fee pays someone for nothing, and verify the initial escrow deposit respects the two-month cushion cap. After closing, calendar two recurring tasks: opening the annual escrow analysis instead of filing it, and comparing its disbursements against your own ledger. RESPA's protections are unusually concrete for a consumer statute — locked fees, banned kickbacks, a counted cushion — but every one of them works better for the buyer who arrives with records.
