Quick Answer
Before you make an offer, confirm your financing is real (a pre-approval, not just a pre-qualification), your cash-to-close is set, you understand the price and the comps, and the contingencies in your contract actually protect you.
Then line up your paperwork, make sure you and your agent have agreed on your walk-away number, and only then write the offer. Do it in that order and you negotiate from strength instead of on emotion.

Start With Your Financing, Not the House
I know how tempting it is to start scrolling listings the moment you decide to buy. But the very first thing to get in order is your financing, and one document in particular: a pre-approval.
In The Essential First-Time Homebuyer Roadmap, I put it this way: a pre-approval is your ticket to the poker table. Without it, sellers and their agents will not take your offer seriously, no matter how strong the number you write. A pre-approval is the verified commitment from a lender that you can actually close. A pre-qualification, by contrast, is a quick no-document estimate, and it does not carry the same weight. See the difference in full at pre-approval vs pre-qualification.
This is also the moment to get your important questions answered before you get too far down the road, everything from what the lender needs to how long the process takes. Take a look at questions you should ask before buying a home so you walk in prepared.
Know Your Number Before You Fall in Love
Touring homes is fun. Getting attached to a home you cannot comfortably afford is how buyers get themselves in trouble. That is why, before you ever set foot in a house you plan to offer on, you should run the affordability mental model and know your numbers cold.
The simple version: your monthly payment is the number that matters most, and the cash you bring to close is the number that gets you to the table. This is an ILLUSTRATIVE example, not a current figure, but it shows the shape of the math. Say a comfortable monthly payment for you lands near a certain amount, and your cash-to-close sits near another. You do the same exercise with your real pre-approval numbers, your real down payment, and your real closing costs before you shop.
Work through how much house you can afford based on your monthly payment, and get clear on how much cash to plan to have when buying your first home. If you want the whole picture up front, how much house you can afford ties it together.
Your Walk-Away Number
Before you negotiate, you and your agent should agree on your walk-away number: the highest price you are genuinely comfortable with, and where you draw the line on the contingencies. Decide this cold, before any emotion is in the room. Then, when a counteroffer pushes past it, you already know the answer. Buyers who pick their walk-away number in the middle of a negotiation tend to drift past it.
Study the Price and the Comps
The asking price on a home is just that: an asking price. It is not automatically what the home is worth, and it is not automatically the number you should pay. Your job before you offer is to figure out whether that price is fair.
That means looking at comparables: homes that recently sold nearby with similar size, age, condition, and features. Compare the subject home to what actually closed, not what is still listed. Understand the difference between asking price vs market value, and let a comparative market analysis ground you in reality.
The goal is to avoid overpaying on emotion. When you know the comps, you can make a confident, defensible offer, and you will know when a seller's number is out of step with what the market says. That is exactly the work that feeds how much to offer on a home.
Confirm the Protections
An offer is not just a price. It is a package, and part of that package is what protects you if something goes sideways between now and closing. Before you sign, confirm each of these is in place and that you understand it.
Earnest money
This is the good-faith deposit that shows the seller you are serious. Know how much is customary in Texas and, just as important, how it is handled if the deal falls through. Get the details on earnest money in Texas.
Your contingencies
Contingencies are the conditions that let you step back without losing your earnest money: a clean financing contingency, an inspection contingency, and any others that matter to you. Read how they work in contingencies in a purchase offer, and make sure the inspection piece is covered in how a home inspection works in Texas.
The option period
In Texas, the option period is your window to do due diligence: inspections, title review, and the freedom to walk for almost any reason. Understand the option fee and option period in Texas before you commit to one.
Your appraisal-gap strategy
If you offer above what the home appraises for, you may need to make up the difference in cash. Decide in advance how you will handle that gap. See what your options are in what happens if the appraisal comes in low.
Check the Property Itself
Beyond the numbers, spend real time on the property and its surroundings. Use this as your scannable pre-offer property checklist. Some of these you verify yourself on the tour, and some the inspection will turn up, so think of this as the full sweep.
- The neighborhood. Drive it at different times of day. Check the commute, the noise, the feel of the streets, and what is nearby.
- Taxes and HOA. Confirm the annual property taxes and whether the home sits in an HOA. HOA dues and rules change your monthly picture and your freedom to change the home. Get the real numbers on HOA fees in San Antonio.
- Condition from the tour. Age of the roof, the HVAC, the water heater, the foundation, and any obvious wear. Note what you saw with your own eyes before the inspector weighs in.
- What inspections will likely turn up. Expect the inspection to flag things you did not notice. Use your option period to get a thorough inspection before you are locked in, and know what your option period actually covers.
Your Team and Your Paperwork
An offer is only as good as the team behind it and the paperwork waiting in the wings. Confirm these three things before you go live.
- Your agent is ready to draft the offer the moment you are, and you are aligned on strategy, price, and your walk-away number. If you have not signed one yet, know what a buyer representation agreement involves.
- Your documentation is lined up so a fast turnaround does not trip you up. Have the list ready at documents needed for your mortgage.
- You understand the timeline from offer to closing, so the deadlines do not surprise you and you know what happens next after your offer lands.
Patrick's Take
"The best offers come from buyers who checked their facts before they fell in love. Do your homework now so you don't negotiate your wallet away later."
Quick Follow-Up Questions
Do I need a pre-approval before making an offer?
Yes, if you want your offer taken seriously. A pre-approval is a verified commitment from a lender, and it tells the seller you can actually close. Without it, sellers and listing agents will often set your offer aside, no matter how good the price looks.
How do I know if the asking price is fair?
Compare the home to recent comparable sales nearby with similar size, age, and condition. That is what determines market value, not the seller's asking price. When you have solid comps, you can tell whether a price is fair or whether it is built on hope.
What should I check about the house before offering?
Check the neighborhood and commute, the property taxes and any HOA, and the condition of the big-ticket items: roof, HVAC, water heater, and foundation. Then use your option period to run a full inspection so the professionals can look where your eye cannot.
What protections should my offer include?
At minimum, earnest money, a financing contingency, an inspection contingency, and the option period that lets you do your due diligence. If you are offering above appraisal price, decide your appraisal-gap strategy up front. These are what keep you from losing money if something goes sideways.
