How to choose a mortgage lender

How to actually compare lenders, what to negotiate, and the red flags that should make you walk.

Most borrowers pick a lender based on a friend’s recommendation, their existing bank, or whoever the realtor suggested. None of those are bad starting points, but none of them produce the best outcome unless you also do an apples-to-apples comparison. The standardized Loan Estimate makes this comparison surprisingly easy — if you actually run it.

Types of lenders, briefly

  • Banks (Chase, Wells Fargo, BoA): broad product set, sometimes competitive on jumbo, often middling on rates.
  • Credit unions: often best on rates and fees because non-profit; membership requirements vary.
  • Mortgage brokers: shop multiple wholesale lenders for you, paid via fees or yield-spread premium. Good for tricky scenarios (self-employed, complex credit, jumbo).
  • Direct lenders / non-bank lenders (Rocket, loanDepot, Better): built on automation, can be competitive but customer-service quality varies wildly.
  • Correspondent lenders: smaller shops that fund and immediately sell to GSEs. Often have the best rates due to lower overhead.

There’s no single “best” type. The point is to shop all of them.

The 3-lender rule

Get Loan Estimates from at least 3 different lenders in the same week. Specifically:

  1. One bank or credit union (use yours if it’s competitive)
  2. One mortgage broker (especially if your scenario is non-standard)
  3. One non-bank direct lender (Rocket, Better, etc.)

Why 3? Below 3 you don’t have enough variance to detect outliers. Above 5 the marginal value drops fast and you’re creating underwriting workload.

Credit-pull timing: pulling your credit at multiple mortgage lenders within a 14-day window counts as a single hard inquiry for FICO purposes. So you can shop without tanking your score.

What the Loan Estimate tells you

The LE is a 3-page standardized form. The pieces that matter:

Page 1, “Loan Terms” box

  • Loan amount
  • Interest rate
  • Monthly P&I
  • Whether rate/payment can change
  • Prepayment penalty (should be NO)
  • Balloon payment (should be NO)

Page 1, “Projected Payments” box

  • Monthly P&I + estimated taxes/insurance/MI
  • Total monthly payment

Page 2, “Loan Costs” section

This is where the biggest differences live:

  • Section A: Origination charges — the lender’s own fees. Highly variable across lenders (the most negotiable line).
  • Section B: Services you cannot shop for — appraisal, credit, etc. Set by the lender.
  • Section C: Services you can shop for — title insurance, settlement. You can use a different provider than the lender suggests.

Page 3, “Comparisons” box

  • In 5 years: how much you’ll have paid total + how much principal you’ll have built. Useful for comparing different rate/point combinations.
  • APR: rolls all costs into a single annualized rate. Useful but imperfect (assumes you hold to maturity).
  • TIP (Total Interest Percentage): total interest as % of loan.

How to actually compare LEs

Two approaches:

Quick: by APR. Lower APR usually = better deal. But APR penalizes loans with higher upfront fees that you might amortize across less time than the full term — so it can favor 30-yr fixed unfairly when you’ll sell sooner.

Better: by 5-year cost. The “In 5 years” box on Page 3 includes both upfront and monthly costs over a realistic hold period.

Best: model your own scenario. If you know your hold period (e.g., “I’m buying a starter home and plan to stay 5-7 years”), compute total cost of each LE for your hold period:

Total cost = (monthly P&I × hold months)
           + closing costs
           − (any lender credits)
           + remaining balance at hold horizon
           − sale proceeds (if comparable across all)

Use the Mortgage Calculator for the monthly P&I and remaining balance figures.

What to negotiate

  • Origination fee (Section A on the LE). Lenders compete on this. If lender X is offering 0.5% origination and lender Y is at 1%, ask Y to match.
  • Rate buydown via points vs lender credit for higher rate. These are two sides of the same trade-off. Some lenders price one side better than the other.
  • Application / underwriting fees. Often waivable, especially if you have a competing offer.
  • Title and settlement if you can shop them. Get a quote from at least one alternative title company in non-promulgated-rate states (TX, FL, NM are promulgated; most others let you shop).

Red flags

Walk if you see any of these:

  • Pressure to lock immediately without explaining the lock terms or rate-lock cost
  • “Rate not available unless we pull credit RIGHT NOW”
  • Fee structure that doesn’t match the LE
  • Refusal to put a quote in writing (“I’ll send the LE after you send me your tax returns”) — they want to anchor you before you shop
  • NMLS license issues — verify any LO at nmlsconsumeraccess.org. Active license, no recent disciplinary actions.
  • Bait-and-switch on rates at closing — the CD must match the LE within tolerances; major changes restart the 3-day clock and you can walk
  • Pressure to use the lender’s preferred title company when you have the right to shop
  • Vague timeline promises with no specific milestones

Realtors often have a preferred lender. Sometimes this is great (reliable closer, smooth process). Sometimes it’s a kickback arrangement (illegal under RESPA but enforcement is uneven). The right move:

  • Get an LE from the realtor’s lender (it’s probably fine)
  • Get LEs from 2 other lenders independently
  • Pick the best one objectively

Existing-bank loyalty

Your existing bank may offer a “relationship discount” of 0.125-0.25% off the rate. Sometimes real, sometimes marketing. Always shop externally too — a 0.25% bank discount on a 7% rate isn’t valuable if the next lender is at 6.5%.

Brokers vs direct lenders

Brokers can sometimes find better rates by shopping wholesale, but their fees vary. Watch for “yield spread premium” structures where the broker is incentivized to put you in a higher-rate loan.

Direct lenders have more skin in the game on the rate but may have fewer products. Better for vanilla scenarios; worse for unusual situations.

For complex situations (self-employed, complex credit, jumbo, non-warrantable condo, mixed-use property), brokers usually win because they can shop niche wholesalers.

What to bring to underwriting

You’ll need most of these:

  • Last 2 years W-2s
  • Last 2-4 weeks of pay stubs
  • Last 2 months of bank statements (all accounts, all pages)
  • Last 2 years of tax returns + business returns if self-employed
  • Photo ID
  • Gift letter + donor bank statements (if applicable)
  • Letter of explanation for any credit inquiries, large deposits, employment gaps

Mistakes to avoid during underwriting

  • Don’t change jobs
  • Don’t open new credit (no Best Buy financing)
  • Don’t make any large unexplained deposits
  • Don’t pay off old collections (counterintuitive, but reactivates them on your credit report)
  • Don’t miss a credit card payment

The lender re-runs your credit and re-verifies employment a few days before closing. A surprise on either kills the deal.

After closing

Your loan is almost certainly going to be sold to another servicer within 30-60 days. This is normal and harmless — the rate and terms don’t change. Watch for the “goodbye” letter from your originator and the “hello” letter from the new servicer. Set up payments at the new place; ignore the old payment portal.
