Everything You Actually Need to Know About Mortgages Before You Apply
Mortgages don't have to be confusing. (They just usually are.) This guide covers what lenders actually look at, which loan types exist, and how the whole process works — in plain English.
What a Mortgage Actually Is
A mortgage is a loan used to buy real estate. You borrow money from a lender, make monthly payments that include principal and interest, and the property itself serves as collateral. If you stop paying, the lender can foreclose.
Your monthly payment typically includes four components, often called PITI: Principal (paying down the loan balance), Interest (the cost of borrowing), Taxes (property taxes), and Insurance (homeowners insurance and, if applicable, mortgage insurance).
Understanding each component helps you evaluate whether a monthly payment fits your budget — and whether a home is truly affordable for your situation.
The Four Main Loan Types
Every mortgage falls into one of a few categories. Each has different requirements, benefits, and trade-offs.
Conventional Loans
Not backed by the government. Typically require a 620+ credit score and as little as 3% down. You will pay private mortgage insurance (PMI) if you put less than 20% down, but PMI drops off once you reach 20% equity.
FHA Loans
Insured by the Federal Housing Administration. Accept credit scores as low as 580 with 3.5% down. Popular with first-time buyers. The trade-off is mortgage insurance for the life of the loan (unless you refinance later).
VA Loans
For eligible veterans, active-duty service members, and surviving spouses. Zero down payment, no mortgage insurance, and competitive rates. One of the strongest loan products available.
USDA Loans
For properties in eligible rural and suburban areas. Zero down payment. Income limits apply. A great option if the property location qualifies.
Fixed Rate vs. Adjustable Rate
A fixed-rate mortgage keeps the same interest rate for the entire loan term — usually 15 or 30 years. Your principal and interest payment never changes, making it easy to budget.
An adjustable-rate mortgage (ARM) starts with a lower rate for an introductory period (typically 5 or 7 years), then adjusts periodically based on market conditions. ARMs can make sense if you plan to sell or refinance before the adjustment period begins.
Not sure which structure makes sense? A loan officer can model both scenarios based on your timeline and goals. Connect with a loan officer in the AMLO network.
What Lenders Actually Look At
When you apply for a mortgage, the lender evaluates five main areas:
- Credit score and credit history
Your score determines program eligibility and your interest rate. Your history shows how reliably you manage debt.
- Debt-to-income ratio (DTI)
Your total monthly debt payments divided by your gross monthly income. Most programs cap this at 43-50%.
- Employment and income stability
Lenders typically want to see two years of consistent employment. Self-employed borrowers need two years of tax returns.
- Down payment and reserves
How much you can put down, where the funds came from, and whether you have savings left over after closing.
- The property itself
The home must appraise at or above the purchase price, and it must meet the condition requirements of the loan program.
The Mortgage Process, Step by Step
Pre-Approval
A lender reviews your credit, income, and assets to determine how much you can borrow. This gives you a price range and shows sellers you are a serious buyer.
House Hunting
With your pre-approval letter in hand, you work with a real estate agent to find a home within your budget.
Offer and Contract
You make an offer, negotiate terms, and sign a purchase agreement. This starts the clock on your closing timeline.
Processing and Underwriting
The lender verifies everything — employment, bank statements, tax returns, the appraisal. This is where the real due diligence happens.
Clear to Close
Once underwriting approves your file, you receive a Closing Disclosure at least three days before closing. Review every line.
Closing Day
You sign documents, wire your closing funds, and receive the keys. The deed is recorded, and you are officially a homeowner.
Closing Costs: What to Expect
Closing costs typically range from 2% to 5% of the purchase price. On a $250,000 home, that is $5,000 to $12,500. These costs include:
- Lender origination fees
- Appraisal fee ($400 - $700 typically)
- Title insurance and title search
- Attorney or escrow fees
- Prepaid property taxes and homeowners insurance
- Mortgage insurance premiums (if applicable)
- Recording fees
Some closing costs are negotiable. In some markets, sellers contribute toward buyer closing costs. And certain down payment assistance programs include closing cost coverage — ask your loan officer about options in your area.

Frequently Asked Questions
What credit score do I need to get a mortgage?
It depends on the loan type. FHA loans accept scores as low as 580 with 3.5% down. Conventional loans typically require 620 or higher. VA and USDA loans have more flexible credit guidelines. A higher score generally means a lower interest rate.
How much do I need for a down payment?
Far less than most people think. FHA requires 3.5%, conventional can go as low as 3%, and VA and USDA loans offer 0% down options. Down payment assistance programs in many states can cover part or all of your down payment.
What is the difference between pre-qualification and pre-approval?
Pre-qualification is a quick estimate based on self-reported information. Pre-approval involves a lender verifying your credit, income, and assets — it carries real weight with sellers and agents. Always aim for pre-approval before shopping for homes.
How long does it take to close on a mortgage?
The average closing timeline is 30 to 45 days from the date your offer is accepted. Some programs, like certain state DPA programs, may take slightly longer due to additional paperwork. Your loan officer can give you a more specific timeline based on your situation.
What are closing costs and how much should I expect?
Closing costs typically range from 2% to 5% of the home purchase price. They include lender fees, title insurance, appraisal, attorney fees, and prepaid items like property taxes and homeowners insurance. Some costs are negotiable, and some DPA programs help cover them.
