The Fed Raised Rates, but It Doesn't Set Your Mortgage Rate: What Katy, TX Home Buyers Need to Know

The Federal Reserve raised interest rates last week. Does that mean the Fed just raised your mortgage rate?

No.

That distinction is important for anyone thinking about buying a home in Katy, TX right now.

On September 16, 2026, the Federal Reserve raised its target range for the federal funds rate by 0.25 percentage point, bringing the range to 3.75% to 4.00%.

At the same time, mortgage rates have been elevated. Mortgage News Daily's daily rate index showed the average 30-year fixed mortgage rate at 7.20% on September 18.

It is understandable for a consumer to look at those two things and conclude:

"The Fed raised rates, so the Fed raised mortgage rates."

But that is not quite how it works.

The Federal Reserve does not directly set the interest rate a mortgage lender offers you on a 30-year fixed mortgage.

And understanding that distinction can help Katy, TX home buyers make better decisions in a market where mortgage rates, available inventory, purchase price and negotiation strategy all matter.

Did the Federal Reserve Raise Interest Rates in September 2026?

Yes. On September 16, 2026, the Federal Open Market Committee raised the target range for the federal funds rate by one-quarter percentage point to 3.75% to 4.00%.

The Federal Reserve cited elevated inflation while noting that economic activity remained solid.

Federal Reserve September 2026 FOMC Statement

But the federal funds rate is not the same thing as a mortgage rate.

That is where some of the confusion begins.

Does the Federal Reserve Set Mortgage Rates?

No. The Federal Reserve does not directly set mortgage rates.

The federal funds rate is a short-term interest rate associated with overnight lending between depository institutions.

A 30-year fixed mortgage is a very different financial product.

Mortgage rates are much more directly influenced by conditions in the bond market, including the market for mortgage-backed securities, along with expectations concerning inflation, economic growth and future monetary policy.

The Federal Reserve can have a significant influence on the broader interest-rate environment, but that is different from saying the Fed determines the rate on your mortgage.

The Federal Reserve Bank of Dallas has similarly explained that there is no direct link between the policy rate and mortgage rates.

Then Why Do Mortgage Rates Sometimes Move When the Fed Makes an Announcement?

Because financial markets are constantly trying to anticipate what comes next.

Investors do not necessarily wait until the Federal Reserve announces a decision and then react to the headline alone.

Markets may have already anticipated a rate increase or decrease well before the Fed meeting occurs.

What can become particularly important is whether the actual decision differs from expectations and what the Federal Reserve communicates about inflation, economic conditions and the possible path of monetary policy going forward.

That is essentially what happened following the September 16 announcement.

Mortgage News Daily reported that the Fed's quarter-point increase had been almost completely anticipated by financial markets before the announcement. According to MND's analysis, the more meaningful bond-market reaction came later as investors processed comments from the Fed chairman and what those comments could mean for future policy.

Mortgage News Daily: No, The Fed Didn't Hike Mortgage Rates Today

This is a good example of why headlines about the Federal Reserve can be misleading for home buyers.

The Fed can influence the environment in which mortgage rates move without directly setting your mortgage rate.

What Are Mortgage Rates Right Now?

Mortgage rates change frequently, sometimes more than once during a day depending on market conditions and individual lenders.

Mortgage News Daily's daily rate index showed the average 30-year fixed mortgage rate at 7.20% as of September 18, 2026.

For comparison, MND reported:

• 7.12% on September 11
• 7.17% on September 14
• 7.22% on September 15
• 7.24% on September 16
• 7.19% on September 17
• 7.20% on September 18

Those daily movements illustrate another important point.

Mortgage rates do not simply move up or down by the same amount as a Federal Reserve rate decision.

I am a REALTOR®, not a mortgage lender. Buyers should discuss their specific interest rate, APR, loan program, qualification and financing options directly with their lender.

Why Does a Change in Mortgage Rates Matter So Much to a Katy, TX Buyer?

Because buyers do not purchase homes based solely on the sales price.

For many buyers, the monthly payment is one of the most important constraints on the purchase.

A mortgage-rate change can affect the principal-and-interest portion of that payment even when the price of the home has not changed.

That can affect:

• The price range a buyer is comfortable considering
• The amount a buyer may qualify to borrow
• The difference between two competing homes
• Whether a buyer prioritizes price or financing-related concessions
• The amount of cash the buyer wants to preserve for closing or after closing

This is why I do not want my buyers looking at mortgage rates in isolation.

We need to understand how the financing works together with the purchase price and the other costs associated with owning the property.

The Interesting Part of the Katy, TX Market: More Choices Can Exist Alongside Higher Borrowing Costs

This is where today's market becomes more nuanced.

Higher mortgage rates can make affordability more challenging for buyers.

At the same time, buyers in portions of the Katy market may have more homes to choose from than they did in a tighter-inventory environment.

That means two things can be true at the same time:

A buyer can have more negotiating leverage on the property while having less purchasing power because of the mortgage rate.

That is why simply asking, "Is this a buyer's market?" does not tell me enough.

I want to know:

• What price range are we considering?
• What Katy market area or neighborhood are we looking in?
• How long has the property been listed?
• Has the seller already reduced the price?
• Are there competing offers?
• What comparable homes are available?
• What financing structure is the buyer using?
• What matters most to the buyer: cash to close, monthly payment, purchase price or some combination?

Katy, TX is not one single housing market. Conditions can vary considerably by price point, neighborhood, school district, age of the home and whether we are comparing resale homes with new construction.

That is why negotiation strategy should be property-specific.

Higher Mortgage Rates Can Change What We Negotiate

When mortgage rates are elevated, buyers may naturally focus on getting the seller to reduce the price.

Price absolutely matters.

But depending on the buyer's financing and the seller's willingness to negotiate, a price reduction may not always be the only option worth evaluating.

For example, a transaction might involve negotiations concerning:

• Purchase price
• Allowable seller contributions toward buyer closing costs
• Repairs
• Other permitted seller concessions
• Terms or timing that have value to one or both parties

Depending on the loan program and transaction, the buyer's lender may also be able to explain whether available seller contributions could be used toward eligible financing or closing costs.

That is a lender conversation.

My role as the buyer's REALTOR® is to help evaluate the real estate transaction and negotiate the terms my client wants to pursue. The lender should explain the financing implications and determine what is permitted under the buyer's loan program.

$10,000 Off the Price Is Not Necessarily the Same as $10,000 Toward Buyer Costs

This is a concept I want buyers to understand before we negotiate.

Imagine a seller has enough flexibility that we believe there may be an opportunity to negotiate approximately $10,000 in value.

Where should we ask for it?

Should we seek a $10,000 price reduction?

Should the buyer ask for an allowable seller contribution toward closing costs?

Could some permitted contribution be useful in connection with the buyer's financing?

There is no universal answer.

The answer depends on the buyer's loan program, available cash, lender requirements, the seller's willingness to negotiate and the buyer's goals.

That is why I like having the lender run the numbers before we assume that one negotiating structure is automatically better.

Negotiating $10,000 of value is one question. Deciding where that $10,000 provides the greatest benefit to a particular buyer is another.

Do Not Focus Only on Principal and Interest

Mortgage rates understandably receive most of the attention when rates move.

But principal and interest are only part of the cost of owning a home.

When I am helping a Katy, TX buyer compare properties, I also want them thinking about:

• Property taxes
• Homeowners insurance
• HOA assessments
• MUD taxes or other assessments where applicable
• Flood insurance where applicable
• Maintenance considerations
• Potential differences between resale and new construction

Two homes with the same sales price can have meaningfully different total monthly housing costs.

A lower-priced home with a higher property tax rate, for example, may not necessarily produce the lower total monthly payment.

That is another reason I do not want buyers choosing homes based solely on the advertised purchase price or mortgage rate.

Should Katy, TX Buyers Wait for Mortgage Rates to Fall?

This is one of the most common questions buyers ask when rates are elevated.

The problem is that none of us can reliably know exactly where mortgage rates will be next month, six months from now or next year.

Waiting for a lower mortgage rate is therefore not a decision based on a guaranteed future outcome.

There is also more than one variable involved.

If rates eventually fall, buyer demand could change.

Home prices could change.

Inventory could change.

Your income, available cash, lease situation or personal needs could change.

That does not mean everyone should buy today.

It means the decision should be based on whether purchasing makes sense for your circumstances today, rather than assuming a particular mortgage rate will be available at a particular time in the future.

Can You Buy Now and Refinance Later?

Possibly, but I would never want a buyer purchasing a home on the assumption that refinancing later is guaranteed.

A future refinance depends on circumstances that do not exist yet.

Those can include future interest rates, property value, equity, credit, income, employment, loan requirements and the costs associated with refinancing.

A lender can explain refinancing considerations in much greater detail.

From my standpoint as a REALTOR®, I want the buyer comfortable with the transaction they are entering into now.

A possible future refinance can be a consideration. It should not be the only reason today's payment works.

Should You Stop Looking at Homes Because Mortgage Rates Increased?

Not necessarily.

If the current financing environment puts the payment outside your comfort level, then changing your timing, price range or strategy may be appropriate.

But if you are financially prepared to purchase and the numbers work for you, a higher-rate environment can also create opportunities that may not exist when buyer competition is stronger.

That could include:

• More properties to consider
• More time to evaluate some listings
• Price reductions on certain homes
• Sellers who may be more willing to negotiate
• Potential seller contributions where appropriate

None of those is guaranteed on a particular property.

But they are reasons I would evaluate the market rather than making a purchase decision based on the mortgage-rate headline alone.

What Should a Katy, TX Buyer Do Right Now?

If you are considering purchasing a home, I would start with three conversations.

1. Talk With Your Lender

Ask what you actually qualify for and, more importantly, what payment you are comfortable carrying.

Ask the lender to explain the interest rate, APR, estimated cash to close and how different purchase prices or permitted seller contributions could affect your particular loan.

2. Look at the Actual Homes Available

Do not assume the market is either good or bad for buyers based solely on a national headline.

Let's look at the neighborhoods and price range that matter to you.

A buyer shopping for a $300,000 resale home may encounter a very different negotiating environment than someone comparing $700,000 new construction.

3. Build the Offer Around Your Priorities

If we identify a property you want to purchase, I want to understand what matters most to you before we structure the offer.

Is your priority reducing the purchase price?

Preserving cash?

Addressing repairs?

Reducing eligible closing costs?

Finding a financing structure that your lender says better meets your goals?

The answer can influence what we negotiate.

The Fed Headline Is Not Your Home-Buying Strategy

The Federal Reserve raised its policy rate last week.

Mortgage rates are elevated.

Both matter.

But neither tells me by itself whether you should or should not buy a home in Katy, TX.

For that, we need to look at your financing, the specific property, current competition, available inventory, the seller's position, total housing costs and your plans.

The question is not simply, "What are mortgage rates today?"

A better question is:

"Given today's mortgage rates and today's Katy housing market, what opportunities do I have and how should I structure my purchase?"

That is a much more useful conversation.

Thinking About Buying a Home in Katy, TX?

If mortgage-rate headlines have left you wondering whether it still makes sense to buy, I can help you evaluate the real estate side of that decision and coordinate with your lender so you can compare actual properties and actual numbers.

I am not a lender, and I will not tell you which mortgage product you should choose. What I can do is help you understand the Katy, TX housing market, identify properties that fit your goals, analyze comparable sales and negotiate the real estate terms of your purchase.
