Quick Answer
Buying your first home is a months-long process, not a weekend job. The single best move you can make is starting six months out: fix your credit, build your savings with intention, avoid taking on new debt, and get a real pre-approval before you ever tour a home.
That runway is what turns a nervous buyer into a confident, ready one. It is when credit mistakes get repaired, savings get seasoned, and the paperwork gets sorted so that when the right house shows up, you can write an offer that actually gets taken seriously.
This page walks you through a month-by-month roadmap, so you can see exactly what comes next and start today. None of the figures here are current market guarantees. Think of them as Patrick's teaching, the sensible method he leans on to guide first-time buyers in San Antonio and the Texas Hill Country.
If buying feels like a scary, mysterious mountain, here is the truth: the path is clearer than it looks, and everyone who does it well starts months out, on purpose. Let's map it together.
Why Start 6 Months Out
Six months is the sweet spot because it gives you real time to do the three things that decide how your mortgage turns out: repair your credit, save with intention, and show a lender a stable, documented file. Credit score improvements, seasoned savings, and a clean paper trail all take months to build. You cannot cram any of them into the two weeks before closing.
Start late and you often make a different set of choices. You settle for a higher rate because you had no time to fix your credit. You rush a down payment with money that has not seasoned. Or you panic and miss the home entirely while your financing is still a mess. Six months out, none of that has to happen. This is your runway, and it is longer than you think.

The First 90 Days: Your Financial Foundation
The first quarter is the most important, because everything the lender will look at later starts here. This is where you build the base that a strong file stands on. Here is what to do, in plain terms.
First 90 Days Checklist
Buying a home can feel overwhelming. This is the part that removes the guesswork.
Pull your credit and review it
Check your real scores and pull the free raw reports. Soft pulls do not hurt your score, so this is free information. Know what is on there before anyone else tells you.
Fix errors and pay down balances
Dispute anything that is wrong, and bring revolving balances down. A good target is keeping utilization below 30%, and ideally under 10% if you can manage it. Credit utilization is one of the fastest levers you control.
Do not open new credit or close old cards
The length of your credit history matters. Closing an old card can shorten it and raise your utilization at the same time. Keep things as they are while you prepare.
Do not co-sign for anyone
A co-signed loan shows up on your report as a debt you are responsible for. Right now, every dollar of debt counts against what you can borrow.
Start building savings automatically
Set up a separate, recurring transfer for your down payment, closing costs, and reserves. When it is automatic, you stop having to remember to save.
Keep big money moves clean and documented
"Mattress money" does not exist to a lender. Your money needs to be in a bank account, and it needs time to season. Large unexplained deposits can raise flags and slow your approval, so keep the paper trail tidy and explainable.
Credit work takes patience, and this is exactly why the six-month runway matters. If you are curious about how your score drives what you qualify for, see what a 620 credit score gets you and how debt-to-income ratio shapes your budget.
Month 4: Get Organized
By month four, your financial base is set, so now you organize. A lender is going to ask for a pile of documents, and having them ready ahead of time is what keeps your pre-approval from dragging. Collect your tax returns, recent pay stubs, bank statements, and any asset or investment account statements. Have a government-issued ID handy too.
This is also the time to pay down any lingering high balances or collections that can still be cleared, and to lock in the no-new-debt discipline you started in month one. Every month closer to closing, your file should look calmer, not busier. For the full list of what to gather, Patrick has a complete rundown in what documents you need for a mortgage application.
Month 3: Get Your Pre-Approval, Not Just a Pre-Qualification
Around three months out, get your pre-approval. Patrick calls it your ticket to the poker table. Sellers and listing agents will not take you seriously without it, and no amount of charm replaces it when there is another interested buyer writing an offer.
Here is the difference in one sentence: a pre-qualification is a quick, unverified estimate based on what you tell the lender, and a pre-approval is a verified commitment backed by your actual documents. It is the difference between a rough guess and a lender signing off on your file. If you want to see both spelled out, here is the pre-qualification vs pre-approval breakdown.
Month 2: Interview Your Team
By month two you should have your team in place: a loan officer and a buyer's agent you trust. Pick the loan officer by asking the Big Questions, not just about today's rate. Ask how they communicate, how fast they return a call, and how they structure an offer so yours gets accepted. Then pick a buyer's agent based on local expertise, responsiveness, and real track record, because they will be negotiating on your behalf.
If you are weighing where to get your loan, understand the difference between a mortgage broker and a direct lender. And know who is working for whom: the buyer's agent versus seller's agent split matters more than most first-time buyers realize.
A Note on the Buyer Representation Agreement
The Buyer Representation Agreement is now a normal part of how buyers work with an agent, so expect to review and sign one when you pick your agent in Texas. The exact requirements come from the Texas Real Estate Commission (TREC), and they can change, so verify the current rules with your agent. Patrick will walk you through every line so you know exactly what you are agreeing to and what you are getting in return.
Month 1: Get Your Money Ready and Set Your Budget
With one month to go before serious house hunting, finalize the number. Settle exactly how much you can afford as a monthly payment, then work backward to a price range. Nail down your down payment, your closing costs, and your reserves so there are no surprises when an offer is accepted.
Patrick's Affordability Mental Model
ILLUSTRATIVE METHOD. This is a teaching shortcut to get you in the ballpark, never a guarantee of what you will be approved for. Your loan officer's underwriting is the only real answer.
- The ceiling: take your annual income, divide by 12, then multiply by 0.38. The result is an illustrative ceiling for your total monthly housing payment (principal, interest, taxes, insurance, and HOA if there is one).
- The reverse ballpark: multiply that monthly payment by about 115 to arrive at a rough purchase-price ballpark. It is a quick sanity check, not a certainty.
- Reality beats the model: your actual approved amount depends on your credit score, debt-to-income ratio, down payment, and the day's rates. Treat the model as a starting point and let pre-approval give you the real number.
For a full walkthrough of the math, Patrick has the complete version at how much house can I afford.
The 30-Day Countdown: What NOT to Do
As you get close, the best thing you can do is protect the file you have worked months to build. This is where deals fall apart, and almost always it is a self-inflicted wound from the last few weeks. Patrick's teaching here is blunt, because it saves closings.
The 30-Day Do-Not-Do List
PATRICK TEACHING. Final guidelines always come from your loan officer.
No new credit cards. Do not open anything new, even for a big purchase you think you have earned.
No car loan, and no buying a car before closing. Patrick says a new car can literally sink your mortgage. A shiny truck in the driveway is not worth losing your house.
Do not finance furniture. The "no payments for a year" offers create a new debt and a new inquiry right when you need a clean file.
No large unexplained deposits or transfers. Gift funds need a proper gift letter, and big money moves need to be explainable. Keep it clean and documented.
Do not change jobs. Unless it is the same line of work and you have discussed it with your loan officer first, a job change can stall your approval. Employment is re-verified at closing.
Do not co-sign or take on new debt. Any new monthly obligation shifts your debt-to-income ratio and can push you over the line.
Keep every account current and pay on time. A single late payment or overdraft in the final stretch can be the thing that derails you. Stay boring with your money.
The underlying idea is simple: nothing about your money should change in the last 30 days except the paperwork moving closer to closing. If you are wondering where first-timers trip up, Patrick lists the biggest mistakes first-time buyers make.
The Week Before Closing: Trust but Verify
You are at the finish line, and now you stay sharp. Do the final walk-through in person, because the home should be in the condition you agreed to. If something looks off, raise it before you sign, not after. Review your Closing Disclosure carefully, and remember the three-business-day rule on the final Closing Disclosure gives you time to read it before closing. Confirm the funding date, and confirm exactly when and how you get the keys.
These last checks are where a good team proves its worth. Patrick's walkthrough list is at the final walk-through checklist, the disclosure is explained in plain language at the Closing Disclosure explained, and the whole day is laid out at what to expect on closing day.
Patrick's Take
"Buying a home is not an event, it is a process, and the people who succeed start early and protect their file. You do not get ready to buy a house the week before you buy it. You get ready months out, on purpose. Give yourself the six months, do the boring work early, and you will walk into that house like you belong there, because by then, you have earned it."
Quick Follow-Up Questions
How far in advance should I start?
Six months is the best all-around runway. It gives you time to fix credit, season your savings, and get pre-approved without rushing. If you are closer than that, start today anyway, the sooner you begin, the better your options. The first step to buying a home can happen at any point in that window.
Can I buy with under a year of credit history?
It can be done, but a thin credit file is one of the tougher situations to underwrite, and it often shows up as a less favorable rate or a higher down payment requirement. That is exactly why starting early matters: six months of on-time payments and low utilization makes your file look stronger by the time you apply. Your loan officer will tell you what is realistic for your particular file.
What kills a mortgage before closing?
The classics: a new car, a new credit card, financing furniture, a job change, a large unexplained deposit, or a late payment in the final stretch. Anything that changes your credit, your income, or your debts in the 30 days before closing can derail an approval. The fix is to keep your financial life exactly where it has been for the past six months.
Should I pay off all my debt before applying?
Not necessarily. Closing old credit cards can shorten your history and hurt you, and paying off everything can leave you short on the reserves lenders want to see. The goal is not a zero balance, it is low utilization, a clean history, and a healthy mix. Pay down balances below that 30% threshold and keep the accounts open, rather than wiping everything out.
The whole process starts a lot earlier than most people realize, which is why it helps to see where the process really begins.
