Preapproval and lenders

A preapproval letter tells sellers a lender is generally willing to lend to you. The process behind it is also your first chance to compare lenders, catch credit problems and learn what the loan will really cost.

Preapproval is the step that turns a budget into an offer a seller will take seriously. The CFPB explains that prequalification and preapproval letters both state how much a lender is generally willing to lend, up to an amount and based on certain assumptions. Lenders use the two words differently, so the label matters less than what the lender actually checked. A letter based on verified pay, assets and a credit report is stronger than one based only on what you told the lender.

Why get preapproved early

The CFPB points out that getting preapproved earlier can reveal credit issues in time to correct them. It also forces you to gather documents before you are under contract and the clock is running. And if a lender evaluates your credit and says you do not qualify, it must give you an adverse action notice, which tells you why.

The documents

Lenders verify income, assets, debts and identity. Expect to provide recent pay stubs, W-2 forms or tax returns, bank and investment statements, identification, and explanations for unusual deposits or credit events. Self-employed buyers usually need more, often two years of returns. The document guide in this file includes a checklist that you can print and tick off.

Lenders and brokers

You can apply directly with banks, credit unions and mortgage companies, or work with a mortgage broker who shops several wholesale lenders for you. Either can work well. What matters is the offer: the rate, the points, the lender fees and how responsive the loan officer is. Applying with more than one lender within a short window lets you compare real Loan Estimates.

The Loan Estimate

After you apply, the lender must give you a Loan Estimate within three business days. The CFPB describes it as a three-page standard form showing the estimated rate, monthly payment and closing costs, plus taxes and insurance and how the rate and payment can change. Because every lender uses the same form, you can lay offers side by side. The Loan Estimate is not an approval; it shows the terms the lender expects to offer if you move forward.

Intent to proceed and the rate lock

Once you choose a lender, you tell them you intend to proceed, and they can begin charging fees beyond a credit report. Locking the rate protects you from market moves for a set period. The site's long reads on comparing Loan Estimates and on rate locks go deeper into both steps.

Picking the lender, then the letter

It helps to choose a lender before you need the strongest letter. Request Loan Estimates from two or three lenders within a short window, compare cost and service, and then ask the lender you prefer for a letter based on verified documents. A letter from a lender that has seen your pay stubs, statements and credit carries more weight than one built on figures you typed into a form. Ask for a letter matched to each offer price, and make sure someone at the lender will answer a listing agent's call. The guides on choosing a lender and on prequalification versus preapproval cover both steps.

How long a letter lasts

A preapproval letter is a snapshot of your credit, income and assets on one day, and it ages as those documents age. Lenders set the expiration date themselves, but they base it on loan program rules. HUD generally limits FHA documents to 120 days old at disbursement, and Fannie Mae requires credit documents, including credit reports and income and asset records, to be no more than four months old on the note date. If your search runs into a fifth or sixth month, expect your lender to ask for fresh pay stubs, new statements and possibly a new credit report before closing. The letter expiration guide in this file explains how to read those limits, includes a date calculator that shows when documents dated on a given day will age out, and lists what a refresh usually involves. It also suggests asking for an updated letter, matched to your offer price, before you submit an offer on an aging one.

Questions buyers ask

How long does a preapproval last?

Each lender sets its own period, often tied to how fresh your credit report, pay stubs and bank statements are. If your letter expires, the lender usually updates the documents and may pull credit again.

Is a preapproval a guarantee of a loan?

No. The CFPB stresses that prequalification and preapproval letters are not guaranteed loan offers. Final approval comes after the lender verifies your finances, appraises the home and reviews the title.
