First-Time Home Buyer Guide Ch. 1: Get Pre-Approved

Get
Pre-Approved

Your application starts here.

Know your budget before you fall in love with a house. In a competitive market, a pre-approval letter is the difference between winning and losing a home. It's the foundation everything else stands on.

Pre-Qualification
A quick estimate

Based on what you tell us. Nothing verified. Not taken seriously by sellers in competitive markets.

The Process

01
Submit Your Application A short application gets the ball rolling. We collect income, assets, and basic credit details to size up the picture. About 15 minutes online.
02
Provide Documentation Pay stubs, W-2s, bank statements, and tax returns. The cleaner the documents, the faster the underwrite.
03
Receive Your Letter A formal pre-approval with a specific purchase price you are cleared for. Your agent will need this in hand before writing an offer.
Sergio's Pro Tip

I'll pull your credit once and do it right the first time, so you're not hurting your score shopping around at three different lenders.

First-Time Home Buyer Guide Ch. 2: Find & Secure Your Home

Find & Secure
Your Home

The right house is rarely the first one.

With a pre-approval in hand, you shop with intention. The right agent, a sharp offer, and a clean inspection turn a listing into a home.

02
Find a Realtor Your realtor is your negotiator. Find someone who knows how to win in a seller's market. If you're buying a new build, you still need your own agent. The builder's agent works for the builder, not you.
03
Find Your Home & Open Escrow Once your offer is accepted, you'll open escrow and put down an Earnest Money Deposit. This shows the seller you're serious and goes toward your closing costs at the end.
04
Submit Your Loan Application Your lender sends disclosures and a Loan Estimate. You sign, confirm the terms, and formal approval begins. This is also when the appraisal and home inspection get ordered.
05
Inspections & Appraisal The inspection reveals the true condition of the property. The appraisal tells the lender its market value. If it comes in low, you can negotiate or walk away. Never skip the inspection.
Sergio's Take

In a tight market, a quick inspection turnaround and a flexible close date can win the deal even when you're not the highest bid.

First-Time Home Buyer Guide Ch. 3: The Finish Line

The Finish
Line

Keys, signatures, and the deed in your name.

From clearing conditions to the day the deed records in your name. Most loans close in 30 to 45 days from contract.

06
Clear Your Conditions Upload all required documents as fast as possible. The speed of your closing depends on how quickly you respond.
07
Final Approval & Closing Disclosure Three days before closing you receive your Closing Disclosure, a full breakdown of every fee. Compare it line-by-line to your Loan Estimate. If anything changed, ask why before you sign.
08
Sign & Fund Your Loan Sign with a title-approved notary, then wire your closing funds. Always verify wiring instructions directly with your escrow officer by phone before sending money.
09
Get Your Keys Once the loan funds and the deed records, you're a homeowner. Welcome home.
Sergio's Most Important Tip

Do not open new credit cards, buy a car, quit your job, or make large deposits during this entire process. Any change to your financial profile can delay or kill your loan, even on closing day. Stay boring until you have the keys.

First-Time Home Buyer Guide Ch. 4: Debt-to-Income Ratio

Debt-to-
Income Ratio

The math underneath the keys.

DTI is the most important number in mortgage qualifying. It tells the lender what percentage of your income goes toward debt, and determines how much home you can afford.

Front-End DTI
Housing only

Principal, interest, taxes, insurance, PMI, and HOA.

The Formula
Monthly Debt ÷ Gross Monthly Income = DTI
Example: $2,400 ÷ $7,500 = 32%

Maximum DTI by Loan Type

Loan TypeMax FrontMax BackSweet Spot
Conventional49.9%49.9%≤ 36%
FHA46.9%56.9%≤ 43%
VANo limit41%≤ 41%
USDA29%41%≤ 41%
Jumbo43%43%≤ 43%
Sergio's DTI Secret

The fastest way to increase your buying power is to pay off debt. Eliminating a $400/month car payment can add $50,000 to $80,000 to your qualifying purchase price. I call this the seesaw game. Less debt on one side means more home on the other.

First-Time Home Buyer Guide Ch. 5: Your Credit Score

Your Credit
Score

A higher score is a lower rate.

Your credit score is your financial report card. Lenders use it to decide whether to approve you and at what rate. Higher score means lower rate and lower monthly payment.

Sergio's Credit Tip

The score on Credit Karma is NOT the same score lenders use. Lenders pull from Equifax, Experian, and TransUnion using a mortgage-specific model: FICO 2, 4, and 5. They take the middle of your three scores. Let me pull the right one before you make any assumptions.
