The Quick Read: Owners are sitting on record equity, but borrowing against it got more expensive this month. The Fed raised its target rate on September 16, and Freddie Mac’s 30-year average crossed 7% on September 24. If you want to rebuild part of your house around work, the question is no longer whether you have the equity. It’s which kind of debt fits the project, and how much of it you can carry if rates keep climbing.
This column is written as of September 28, 2026. Every market figure below carries its source and date.
Key Takeaways
- Equity is deep. Mortgage holders held $18 trillion in equity in the second quarter, per a report covered on August 10, and $11.7 trillion of it is tappable.
- The Fed voted 12–0 on September 16 to raise its target range to 3-3/4 to 4 percent. That is the first hike since July 2023.
- Floating-rate debt, like most HELOCs, reprices with the Fed. Fixed-rate debt follows the bond market instead.
- Deep equity says nothing about the price of tapping it. Those are two separate questions.
- My view: small, phased upgrades suit a variable line. A big renovation deserves a hard look at fixed structures, or at waiting.
What changed in September?
The Fed hiked, and the 30-year fixed crossed 7%. Two dated facts set the tone this month.
The Federal Reserve’s FOMC statement on September 16 announced a 12–0 vote. The committee raised the fed funds target by a quarter point, to 3-3/4 to 4 percent, and described inflation as elevated. CNBC called it the first hike since July 2023. It also reported that 16 of 18 policymakers on the Fed’s dot plot expect another hike this year. The next meeting is October 27–28.
Then the mortgage market followed. Freddie Mac’s survey put the 30-year fixed at 7.03% for the week of September 24. That was up from 6.95% the week before, and up from 6.30% a year earlier. NPR reported it was the first reading above 7% since January 2025. By the end of February, Freddie Mac’s survey had briefly shown the 30-year fixed dipping below the 6% mark.
That’s a move of more than a full point in seven months.
Which number you read matters, so here are three of them:
| Source | Reading | Date |
|---|---|---|
| Freddie Mac survey | 7.03% | Week of Sept. 24 |
| MBA survey | 7.12% | Week ending Sept. 18 |
| Mortgage News Daily index | 7.50% | Sept. 28 |
They differ by design. Freddie’s number is a weekly average of conforming purchase loans, and it lags. The MBA’s weekly survey put its 30-year contract rate at 7.12% for the week ending September 18, up from 6.97%. Mortgage News Daily’s index closed at 7.50% on September 28, its first reading that high since April 30, 2024. MND also noted that its daily index first broke 7% on September 10, two weeks before Freddie’s average caught up.
I’ll use Freddie’s number as the reference point in this column. I’ll use the daily index when I talk about where things stand today.
Why does the Fed hike matter for a home-equity line?
It matters immediately, because most HELOCs are variable. A HELOC is a revolving line secured by your home. Most are priced as a benchmark called the prime rate plus a margin. One HELOC explainer from August notes that some lenders let you convert part of a balance to a fixed rate. The basic mechanic is simple. When the Fed hikes, prime rises, and the cost of the line follows.
Fixed mortgage rates work differently. They depend on the 10-year Treasury yield, not directly on the Fed. The MBA says the 10-year is close to 5.2 percent, against about 4 percent in February. It points to energy prices, inflation, tighter policy expectations, strong growth and federal debt. Mortgage News Daily says oil explains little of the recent rise. Nobody has a clean answer on the cause.
The practical result is an odd split. Fixed mortgage money was already expensive before the hike. Floating home-equity debt just got more expensive on top of it.
What does the equity picture look like?
It looks strong, and it is concentrated. HousingWire’s coverage of ICE’s August report, published August 10, put total mortgage-holder equity at $18 trillion in the second quarter. That is an all-time high. Of that, $11.7 trillion is tappable. “Tappable” means the amount you could borrow while leaving a cushion of equity in the house.
Two things keep that number in proportion.
First, growth is modest. A year earlier, total equity was $17.8 trillion, so the record is a small step up, not a surge. ICE’s analysts also warned that higher rates may limit further gains in home prices in the second half. ICE had annual price growth at 1.5% in July, a 14-month high.
Second, equity is not evenly spread. ICE’s August report counted about 813,000 underwater borrowers, up 44% from a year earlier. They are concentrated among FHA and VA borrowers. If you bought recently with little down, your equity picture may look nothing like the headline.
Borrowers have also been using that equity. ICE’s June report, published June 8, said first-quarter equity withdrawals were the highest for a first quarter since 2021. First-quarter second-lien lending was the strongest in nearly two decades. The logic is the lock-in effect. Owners with low-rate first mortgages keep them and borrow on top. ICE’s July report, published July 6, said Baby Boomers made up 31% of second-quarter cash-out refinance activity. It flagged higher debt-to-income ratios for that group.
That last detail is worth sitting with. Plenty of people are borrowing. Some of them are stretching.
Is a home office worth borrowing for?
Sometimes. It depends on the scale of the project and the structure of the debt. I found no dated public data on home-office, flex-room or smart-home spending this month. So what follows is my framing, not a sourced trend.
Here is how I think about it. A home office is not a typical home-improvement project. It changes how you use the house every day. A dedicated room, a converted spare bedroom, a wired-up corner with decent lighting and good connectivity: these can pay back in comfort and productivity. They don’t always pay back in resale value. Buyers in your area may value the space, or they may see a fourth bedroom turned into a den.
That is a real risk. Don’t borrow against your house for a project whose payoff is personal, then assume the market will repay you. It might, or it might not, and you should plan as though it won’t.
The smart-home piece deserves the same skepticism. Lighting, climate control and network upgrades are useful. But gadgets age quickly in a way that a roof does not. I would not finance a device with a debt that outlasts it.
How do the financing options compare?
Each structure trades off rate risk, cost and what you give up. Here is the side-by-side, in words, with no figures.
| Structure | Rate type | Main trade-off |
|---|---|---|
| HELOC | Usually variable | Cost rises with the Fed |
| Fixed-rate home equity loan | Fixed | Set amount, set cost |
| Cash-out refinance | Usually fixed | Replaces your first mortgage |
| Paying from savings | None | Uses liquidity |
Think of the cash-out refinance first, because it is where the trap is. Say you hold a first mortgage well below today’s market. A cash-out refinance replaces that loan with a new one at current rates. You’d be raising the cost of your entire balance to fund one project. If a rate moves from 4% to 7%, the difference is three full points on every dollar you owe, not just the new dollars. That is the lock-in effect in action, and it is why second liens have been so popular.
A second lien leaves your first mortgage alone. For that reason, HELOC programs are where most owners with low-rate first loans end up looking. The page carries the current guidelines, and what you qualify for is subject to lender guidelines and your file.
The catch is the floating cost. If you draw heavily on a variable line, you take on rate risk for as long as the balance stays open. After this month’s hike, and with most Fed officials expecting another, I treat that risk as live.
A fixed-rate second lien removes the rate risk and adds a known cost. You give up flexibility. You can’t draw, repay and draw again. For a defined, one-time project, that can be the better fit.
One more thing for readers who own rental property. Equity on an investment property is a different conversation, with different lenders and different rules. If that’s you, these two pieces on using home equity to buy a rental and the guide “Who Does Home Equity Loans on Investment Property” cover it in more depth.
What’s happening in the wider housing market?
Sales are soft, supply is rising, and buyers are hesitating. The broader market matters because it shapes whether a renovation pays back and whether your equity holds.
NAR’s report on August existing-home sales, released September 10, showed sales down 2.0% from July and 1.2% from a year earlier. The median price was $429,100, up 1.6%, the 38th straight month of year-over-year gains. Inventory rose to 1.62 million homes, which is 4.9 months of supply. NAR’s Lawrence Yun says that is the highest in more than ten years.
Prices are still rising, then. But the cushion is thin, and supply is building.
On the new-home side, the Census Bureau’s August report, released September 24, showed sales at 684,000 annualized. That was up 6.4% from July, but Census says the change is not statistically significant. The median new-home price was $393,700, down 5.8% from a year earlier. Inman, citing NAHB, reported that 38% of builders cut prices in September and 66% used incentives.
The refinance side has gone quiet. The MBA said the Refinance Index fell 3% in the week ending September 18 and sat 62% below a year earlier. The MBA’s Mike Fratantoni said refinancing was at its slowest pace since February 2025. Rate-and-term refinancing is largely off the table at these levels. That leaves second liens and home equity as the main way to borrow against a house.
A reminder on a common misreading. Falling new-home prices do not mean your home lost value. Census prices reflect the mix of homes sold. Existing-home prices are still up.
My take
Equity is an asset, not an instruction to spend it. Record tappable equity tells you what you could borrow. It says nothing about what borrowing costs, or whether the project deserves the debt. I see those two ideas get blurred constantly, and the headline numbers encourage it.
I’ll say it plainly. Remote work is not going away, and the desire to reshape a house around it is reasonable. A separate room with a door, good light and a reliable connection is a fair thing to want. But September’s data changes the price of wanting it.
Here is my read on where this goes. The Fed has signalled more hikes, and its own projections show most members expect another this year. The bond market has already pushed fixed rates past 7%. I can’t tell you whether rates peak in October or keep rising into next year. Neither can anyone else. The MBA’s own forecast has rates near 6.8%, and it cut its origination forecasts for 2026 and 2027 in the same piece. Forecasts move.
So I plan for the worse case. If you borrow on a floating line, ask whether you could carry the balance if the cost rose by a point or more. If the honest answer is no, the structure is wrong for you, however much equity you hold.
This is a genuine toss-up for some people. A homeowner with modest plans and a healthy cushion can run a variable line sensibly. A homeowner planning a large build, with a tight monthly budget, is taking a bigger bet than the marketing suggests. The Boomer debt-to-income flag in ICE’s July data is the kind of signal I’d rather not ignore.
What I’d do now
Match the debt to the project, and keep room to be wrong. This is practical guidance, not advice to buy or sell anything.
1. Split the project into phases. Start with the more affordable changes: layout, lighting, a proper desk setup. Pay for those from savings if you can. Borrow only for what’s left.
2. Decide fixed or floating before you shop. A defined, one-time project often suits a fixed structure. An ongoing series of small draws can suit a line. In a rising-rate environment, I lean toward fixed for anything large.
3. Protect your first mortgage if it’s low. Before you look at a cash-out refinance, compare it against a second lien. Replacing a low-rate first loan has a real cost that only shows up in the total balance.
4. Ask how a variable line reprices. Find out what benchmark it follows, what the margin is, and whether you can convert part of the balance to fixed later. Those terms differ by lender and program.
5. Stress-test the carry. Take a hypothetical move upward in borrowing costs and see whether your budget still works. If it doesn’t, borrow less.
6. Compare quotes side by side. If you choose a fixed structure, the quoted terms hold only for a limited period. Floating means accepting whatever the market does between now and closing. Quotes gathered on different days aren’t comparable, because the market moved in between. Collect them close together.
7. Don’t count on resale to repay you. With housing supply elevated and sales soft, a home-office upgrade is something you borrow for to live in, not to flip.
If you want to go further, read the HELOC programs page before you talk to anyone. It is the source of truth for current guidelines.
Where I’d end up if it were my house
I’d wait on the big build and do the small one now. Reasonable people disagree, and I could be wrong if rates fall back. But the information I have points one way. Rates are rising, more hikes are expected, and the equity I hold is more useful as a cushion than as a funding source for a room I can partly build from savings.

Frequently Asked Questions
Is now a bad time to open a HELOC?
Not necessarily, but it is a riskier one for floating debt. The Fed raised its target range on September 16, and most HELOCs reprice with prime, so the cost moves with policy. Most Fed officials expect another hike this year. If you open a line, plan for the cost to rise, and ask whether part of a balance can be converted to fixed.
Does record home equity mean I can afford to borrow against it?
No. Record equity measures how much you could borrow, not what it costs. ICE’s figures, covered by HousingWire on August 10, put tappable equity at $11.7 trillion. That number counts equity above a cushion. It says nothing about interest cost, your income or your budget. Affordability is a separate test.
Should I refinance my whole mortgage to fund a home office?
Usually not if your current first mortgage is well below today’s market. A cash-out refinance replaces the whole balance at current rates. Freddie Mac’s survey put the 30-year fixed at 7.03% for the week of September 24, more than a point above February’s low. A second lien leaves your existing loan alone. Which fits best is subject to lender guidelines and your file.
Will a home office raise my home’s resale value?
I can’t point to dated public data that says it will. NAR reported on September 10 that supply reached 4.9 months, the highest in more than ten years, so buyers have choices. A space that suits you may not add much to a sale price. Treat it as a cost of living well, not an investment.
Are fixed mortgage rates going to follow the Fed higher?
Not one-for-one. Fixed mortgage rates track the 10-year Treasury yield and the bond market more than the Fed’s target. Whether it keeps rising depends on inflation, energy prices, growth and federal debt, and economists disagree on the weights.
