Mortgage Companies

The sector at a glance

Residential mortgage lending is the business of originating, pricing, underwriting, closing and selling home loans — purchase, refinance, cash-out, home equity and investor financing — through three competing channels: retail lenders and banks that go direct to the consumer, wholesale lenders that price loans through independent mortgage brokers, and correspondent lenders that fund and sell closed loans upstream. The people doing the selling are licensed loan officers and mortgage brokers whose names sit on an NMLS number, and almost all of their business comes from referral relationships — real estate agents, builders, CPAs, financial planners and past clients — rather than from the lender's brand. That makes this one of the most heavily regulated marketing environments in American business: Regulation Z governs what a rate ad may say, Regulation N bans deceptive mortgage advertising outright, RESPA Section 8 criminalizes paying for referrals, and ECOA and HMDA make every marketing decision a potential fair-lending record. A mortgage marketing program that ignores those constraints is not aggressive, it is unshippable. The buyer is a homebuyer or homeowner making the largest financed decision of their life, usually in a compressed window, usually against a rate that moves daily.

Topic guides

Concepts

Regulation Z trigger terms

Under TILA's Regulation Z, stating certain specifics in a closed-end credit ad — an amount or percentage of down payment, the number of payments, the period of repayment, or the amount of any payment or finance charge — 'triggers' mandatory additional disclosures in the same ad, including the APR. The most common compliance failure in mortgage social media and paid search.

Regulation N / MAP Rule

The Mortgage Acts and Practices Advertising Rule, enforced by the FTC and CFPB, which prohibits any material misrepresentation in a commercial communication about a mortgage — rate, fees, terms, government affiliation, savings claims — and requires records of ads be kept. It reaches every channel, including a loan officer's personal social posts.

RESPA Section 8

The federal prohibition on giving or accepting any fee, kickback or thing of value in exchange for the referral of settlement service business. It is criminal, it has no de minimis exception, and it is the reason 'buying' realtor referrals — with leads, dinners, ad spend or split costs — is the defining legal risk of mortgage marketing.

Marketing Services Agreement (MSA)

A written arrangement in which a lender pays a settlement service provider for actual marketing services rather than for referrals. Legal in principle, heavily scrutinized in practice: payment must be fair market value for services genuinely performed and cannot vary with referral volume.

Co-marketing with real estate agents

Sharing the cost of a flyer, listing ad, portal placement or event with an agent. The RESPA line is proportionality and value — a lender may pay only for its own share of the exposure it receives, and cost-sharing that quietly subsidizes the agent is a Section 8 problem regardless of the invoice.

UDAAP

Unfair, Deceptive or Abusive Acts or Practices — the CFPB's catch-all authority that reaches conduct no specific rule addresses. A statement can be technically accurate under Regulation Z and still be deceptive under UDAAP if the net impression misleads a reasonable consumer.

ECOA / Regulation B

The Equal Credit Opportunity Act and its implementing regulation, prohibiting discrimination on prohibited bases in any aspect of a credit transaction — including advertising, prescreening and who is solicited — and requiring adverse action notices with specific reasons.

Fair lending

The combined ECOA and Fair Housing Act framework covering disparate treatment and disparate impact. It applies to marketing reach, pricing discretion, underwriting overlays and steering, which means a targeting decision is a fair-lending decision.

HMDA

The Home Mortgage Disclosure Act, requiring covered lenders to collect and report loan-level application data including geography, applicant demographics and pricing. The public HMDA dataset is what regulators, journalists and plaintiffs use to detect lending disparities.

Redlining enforcement

Government action against lenders that avoid serving majority-minority neighborhoods, proven substantially through marketing footprint, branch and loan officer placement, and referral sources rather than through any written policy. Where a lender advertises is evidence.

NMLS identification requirement

Licensed originators and companies must display their NMLS unique identifier in advertising and on consumer-facing communications. It is the cheapest compliance item in the industry and among the most frequently missed on social profiles and landing pages.

State-by-state licensing

Mortgage licensing is granted per state per entity and per individual, with separate approvals, bonds, education and renewal cycles. A lender may only solicit and originate where licensed, which makes geographic targeting a licensing question before it is a marketing question.

LTV and CLTV

Loan-to-value is the first-lien loan amount divided by the property value; combined loan-to-value adds all subordinate liens. Together they drive eligibility, mortgage insurance, pricing and whether a second lien can go behind the first at all.

DTI (front-end and back-end)

Debt-to-income ratio. Front-end counts only the housing payment — principal, interest, taxes, insurance, HOA — against gross monthly income; back-end adds all other monthly obligations. Back-end is the ratio most programs actually judge, and rising taxes and insurance push it up without the borrower borrowing a dollar more.

Credit score tiers

Lenders price and qualify in score bands rather than on a continuous scale, using the score model the agency requires and typically the middle of three bureau scores (or the lower middle on joint applications). A few points can cross a tier boundary and change pricing materially.

LLPA (loan-level price adjustment)

Agency pricing add-ons applied by risk characteristic — credit score, LTV, occupancy, property type, loan purpose, subordinate financing. LLPAs are why two borrowers on the same day with the same lender get different rates, and the grids are published by Fannie Mae and Freddie Mac.

Conforming loan limit

The maximum loan amount Fannie Mae and Freddie Mac may purchase, set annually by FHFA under the HERA formula. For 2026 the baseline one-unit limit is $832,750, with the high-cost ceiling at $1,249,125; the number changes every November and must never be hardcoded into evergreen copy.

Jumbo loan

A loan above the applicable conforming limit for its county, ineligible for agency purchase and therefore priced and underwritten to investor or portfolio guidelines — usually tighter on reserves, documentation and appraisal, and sometimes cheaper than conforming depending on the investor appetite of the moment.

Non-QM

Lending outside the Qualified Mortgage safe harbor — alternative documentation, higher DTI, interest-only, recent credit events. Non-QM is not subprime by definition; the Ability-to-Repay rule still applies, it is simply satisfied with documentation other than the QM template.

DSCR loan

Debt Service Coverage Ratio financing for investment property, qualified on the subject property's rent relative to its payment rather than on the borrower's personal income. The dominant product for investors with complex tax returns, usually closed in an entity.

Bank statement loan

Self-employed qualification using deposits across a set number of months of personal or business bank statements with an expense factor, instead of tax returns. Priced above agency and structured very differently between investors, which is why comparison content performs.

ARM: index, margin and caps

An adjustable-rate mortgage's rate equals a published index plus a fixed margin, constrained by initial, periodic and lifetime caps after the fixed period ends. The margin and caps, not the teaser rate, determine what the loan actually becomes.

Buydown (temporary and permanent)

A temporary buydown such as a 2-1 uses escrowed seller or lender funds to reduce the payment for the first years while the note rate stays unchanged; a permanent buydown uses discount points to lower the note rate for the life of the loan. Confusing the two in an ad is a Regulation Z and MAP Rule exposure.

Discount points and lender credits

Points are prepaid interest the borrower pays to lower the rate; a lender credit is the mirror image, a higher rate that generates rebate pricing to cover closing costs. Both are quoted as a percentage of the loan amount and both must be reflected in the APR.

APR vs note rate

The note rate determines the payment; the APR expresses rate plus prepaid finance charges as an annualized cost, which is why it is higher. Advertising a note rate without the APR where required is the classic trigger-term violation.

Rate lock, float-down and extension

A lock fixes pricing for a stated number of days and is a real commitment on both sides. A float-down lets the borrower capture an improvement, usually once and within limits; an expired lock costs an extension fee or, worse, forces a worse-case repricing. Lock discipline is a margin issue for the lender, not a courtesy.

TRID

The TILA-RESPA Integrated Disclosure rule governing the timing, content and accuracy of mortgage disclosures. It sets when a Loan Estimate must issue, when a Closing Disclosure must be received, and what happens when figures change — the timing spine of every purchase contract.

Loan Estimate and Closing Disclosure

The two standardized TRID forms. The Loan Estimate must be delivered within three business days of application and shows estimated rate, payment and costs; the Closing Disclosure must be received at least three business days before consummation and shows the final terms. Comparing them side by side is how a borrower detects a bait-and-switch.

TRID tolerance cure

When a fee exceeds its permitted tolerance without a valid changed circumstance, the lender must refund the excess to the borrower and issue a corrected disclosure, generally within 60 days of consummation. Tolerance cures are a direct hit to the loan's profitability and a common audit finding.

AUS (DU and LPA)

Automated Underwriting Systems — Fannie Mae's Desktop Underwriter and Freddie Mac's Loan Product Advisor — that return an eligibility recommendation and a documentation waterfall. The findings define what the file must prove; an approval is the beginning of underwriting, not the end.

Manual underwrite

Underwriting by a human against program guidelines when the AUS refers or the program requires it, typical on some FHA and VA files and on thin or damaged credit. Compensating factors, reserves and residual income carry the file.

Condo warrantability

Whether a condominium project meets agency project standards — owner-occupancy ratio, investor concentration, delinquent HOA dues, litigation, reserve funding, commercial space, and post-Surfside structural and special-assessment questions. A perfect borrower in a non-warrantable project needs a completely different loan.

Appraisal and appraisal waiver

An independent opinion of value supporting the collateral. Fannie Mae and Freddie Mac may offer waivers (value acceptance) on qualifying low-risk files using their property databases, along with hybrid and desktop options — faster and cheaper, but not available on demand and not something to promise a borrower up front.

Reconsideration of value (ROV)

The borrower's formal route to challenge an appraised value with relevant comparable sales or factual corrections. Federal guidance requires lenders to have a clear ROV process and to disclose it, partly as an appraisal-bias safeguard.

PMI and MIP

Private mortgage insurance on conventional loans above 80% LTV, cancellable under the Homeowners Protection Act as equity builds, versus FHA's Mortgage Insurance Premium, which on most modern FHA loans persists for the life of the loan unless the borrower refinances. The cancellation difference is often the entire FHA-versus-conventional argument.

FHA UFMIP and VA funding fee

One-time upfront charges — FHA's Upfront Mortgage Insurance Premium and the VA's funding fee — normally financed into the loan rather than paid in cash. VA funding fee amounts vary by service, down payment and prior use, and are waived for certain disabled veterans; both are set by the agencies and must be quoted from the current schedule.

Escrow / impound account

A lender-held account collecting monthly amounts for property taxes and insurance and paying them when due. In Texas, rising appraised values and insurance premiums make escrow analysis a recurring payment-shock event that lands on the loan officer's phone rather than the servicer's.

Title commitment and survey

The title company's promise to insure, listing requirements and exceptions, paired with the survey showing boundaries, easements and encroachments. Unresolved exceptions and missing surveys are among the most common causes of a delayed closing.

Seller concessions

Seller-paid closing costs, prepaids or buydown funds, capped by program according to occupancy and LTV. In a buyer's market a concession toward a rate buydown usually buys more monthly relief than the same dollars taken off the price.

Gift funds and reserves

Gift funds are down payment or closing funds from an eligible donor, documented with a gift letter and a traceable transfer proving no repayment obligation; reserves are verified liquid assets remaining after closing, measured in months of housing payment. Programs differ on who may give, how much of the borrower's own money is required, and how many months of reserves investment property or multiple financed properties demand.

Self-employed income and P&L

Qualifying income derived from tax returns with add-backs for depreciation and amortization, business liquidity tests, K-1 distributions and ownership percentage — or from bank statements and CPA-prepared profit-and-loss statements on alternative-documentation programs. The most common reason a high earner is told no.

Rate sheet and basis points

The daily pricing grid a lender publishes by program, rate and lock period, expressed in points and basis points where 100 basis points equals one percent of the loan amount. Reading a rate sheet — base price, adjustments, lock cost — is the core literacy of an originator.

Secondary marketing

The desk that prices loans, hedges the pipeline against rate movement, and sells production into the agencies or to investors. It is where a lender's margin actually lives, and it is why pricing changes intraday when the bond market moves.

MSR (mortgage servicing rights)

The contractual right to service a loan and collect the servicing fee, retained or sold at origination. MSR values rise when rates rise and prepayments slow, which is why servicing income cushions lenders in exactly the market that starves origination.

Gain-on-sale margin

The spread between what a loan costs to originate and what it sells for in the secondary market, the primary revenue metric for an independent mortgage bank. Competitive pricing wars compress it directly.

Pull-through rate

The share of locked loans that actually close. It drives hedging accuracy and cost per funded loan, and it is the metric that exposes a pipeline full of shoppers rather than committed borrowers.

Cost per funded loan

Fully loaded origination cost — commissions, salaries, technology, occupancy, corporate allocation — divided by loans closed. Reported quarterly by the Mortgage Bankers Association, it is the number that determines whether a branch or channel survives a low-volume year.

Trigger leads

When a lender pulls a mortgage credit report, the bureaus may sell notice of that inquiry as a prescreened lead, so competitors call the borrower within hours. Long the industry's most hated practice, it is now sharply restricted by federal law — see the developments section — and the fallout reshapes lead-buying economics for every originator who relied on it.
