Homebuilder Stocks Falling: What Margins and Incentives Signal

Why are homebuilder stocks falling?

Homebuilder stocks are falling because higher borrowing costs are hitting the three things builders depend on: buyer demand, pricing power and profit margins. When mortgage rates rise, fewer households qualify for a loan. Builders respond with discounts, mortgage rate buydowns and closing-cost credits to keep sales moving. Those concessions protect volume but cut into profit per home, and investors tend to sell shares when they expect earnings to shrink.

That is the argument in a recent video from the creator Michael Bordenaro Clips, published September 29, 2026. He says builder shares have been hit hard as Treasury yields climbed and mortgage rates moved back above 7%. His boldest claim is that builders are trading at valuations seen only twice before. This article walks through the numbers he cites, adds context on what they do and do not mean, and looks at what the data point to for people shopping for new construction.

The key figures in the video

The creator cites a handful of data points. They are his figures from the video, not independently verified here, so treat them as the starting point for your own checking.

For rates, the benchmark most reporters use is the weekly Freddie Mac Primary Mortgage Market Survey. Because different lenders quote different rates, a figure "above 7%" can mean different things depending on loan type, credit score and points paid. Check the current weekly reading before assuming where the market stands today.

How higher rates squeeze builders

Demand falls first

A mortgage payment is the main cost for most buyers, so a rise in rates reduces the price a household can afford without any change in income. Bordenaro adds a second layer: many households also carry other debt, so higher interest costs elsewhere leave less cash for a down payment and push up debt-to-income ratios. A higher ratio can reduce the loan amount a lender will approve.

This is not unique to new homes, but builders feel it acutely. They have to sell inventory they have already started or finished, and they carry costs for land, labor, materials and construction financing while they wait. For more on how rate moves feed into borrowing costs, see our look at the 10-year Treasury yield spike and what it means for mortgages.

Incentives protect volume, not margins

Resale sellers can only cut the price or wait. Large builders have another tool: they can pay to lower the buyer's rate. A temporary buydown or a below-market rate through a builder-affiliated lender lowers the monthly payment while keeping the sticker price intact. The cost shows up on the builder's books as a concession, which reduces gross margin.

Bordenaro expects more of this: bigger buydowns, more freebies and creative financing to get buyers qualified. His view is that builders will keep selling homes, but at lower prices and with weaker profitability. That is a coherent argument. Volume can hold up while earnings fall, and share prices usually follow earnings expectations rather than closings alone.

Why oil and inflation come into it

The video also points to Brent crude at a little over $107 a barrel, tied to ongoing conflict involving Iran. His reasoning is that higher energy prices keep inflation elevated, which raises the odds that the Federal Reserve holds or raises rates, which pushes yields and mortgage rates up. Whether inflation is driven mainly by oil, money supply or something else is a debate economists have not settled, and the creator's view that money supply is the main driver is his own. What is less contested is the transmission: inflation worries tend to lift long-term yields, and mortgage rates track those yields. You can check the latest inflation readings at the Bureau of Labor Statistics CPI page and Brent prices at the U.S. Energy Information Administration.

What "below book value" actually means

The most eye-catching claim is that builder stocks trade below 0.8 times book value. Book value is a company's assets minus its liabilities, also called shareholder equity. A price-to-book ratio of 0.8 means the market values the company at about 80 cents for every dollar of net assets on the balance sheet.

Bordenaro says this has happened only in 1990 and in 2008-2009, and that both periods coincided with weakness in home prices, though much less so in 1990. He argues that today's situation differs because affordability is strained across the board.

A signal of pessimism, not insolvency

At one point the creator describes this as investors treating builders as essentially bankrupt. That goes further than the numbers support. A company is insolvent in the balance-sheet sense when liabilities exceed assets, which would mean book value is negative. A ratio below 1.0 means book value is still positive; the market simply doubts the assets are worth what the books say, or expects returns to be weak.

For builders, the doubt usually centers on land and lots held at cost. If home prices or sales pace fall, land bought at higher prices may be worth less than carried, and future profits from it shrink. A discount to book is the market pricing in that risk. It is a warning about earnings and asset values, not a declaration of failure.

Where the bearish view may go too far

A fair reading needs some counterpoints to the creator's thesis.

• Balance sheets differ from 2008. Many large public builders entered this period with far less debt relative to equity than they had before the financial crisis, and many have lots held under option contracts rather than owned outright. Check each company's latest filings rather than relying on a general comparison.
• Stock prices are not home prices. Equity markets move on expectations, often ahead of fundamentals, and can rebound quickly if yields fall. A low valuation does not guarantee a price decline in homes.
• Supply is different. Resale inventory remains limited in many markets because homeowners with low-rate mortgages are reluctant to sell, which keeps pressure on new construction as a source of supply. The creator himself acknowledges that many sellers have equity and little pressure to move.
• Local markets vary widely. National claims about new and existing home prices hide big differences between, for example, oversupplied Sun Belt metros and tighter Northeast and Midwest markets.
• The creator has a stated stance. He says he has hoped for lower prices for people priced out of the market. That does not make him wrong, but it is worth knowing when weighing a forecast.

What this means for you

If you are buying new construction

Builders under margin pressure are often more flexible on incentives than on list prices, because a price cut can reset the value of every home in a community while a concession is a one-time cost. Ask for the full package in writing and compare it with a straight price reduction. A temporary buydown lowers your payment for a limited period, but your rate then steps up, so you should be able to afford the payment at the full note rate. Closing credits tied to the builder's preferred lender may come with a higher rate than you could find elsewhere, so get a competing quote. Our guide on how buyers can negotiate seller concessions covers these trade-offs.

If you are selling a resale home

Your home competes with new construction that comes with a rate buydown. If a builder down the road can offer a lower monthly payment on a comparable house, your list price has to account for that. Study local sold prices and price-cut activity rather than last year's comparable sales. Sellers who set prices based on what they paid or what neighbors got in earlier years often find the market has moved. Our report on falling buyer demand and seller price cuts looks at what the broader data show.

If you own a home and are not selling

Falling builder stocks do not change your mortgage or your home's value on their own. If you have a low fixed rate and stable income, a slowing market mostly affects your future options, such as whether you can sell and buy at a price that works. Avoid making decisions on a single week's headlines.

If you invest in builder stocks

Nothing here is a recommendation. A low price-to-book ratio can reflect real risk as well as potential value. Review company filings, backlog, cancellation rates and gross margin trends, and consider speaking with a licensed financial adviser.

What to watch next

Several public indicators will show whether builder stress is easing or deepening:

1. Treasury yields and mortgage rates. The 10-year Treasury yield on FRED and the weekly Freddie Mac survey are the clearest drivers. Sustained declines would help builders more than any incentive.
2. Builder sentiment. The NAHB/Wells Fargo Housing Market Index reports the share of builders cutting prices and offering incentives each month.
3. New-home sales and inventory. The Census Bureau's new residential sales report tracks sales, median prices and months of supply for new homes.
4. Builder earnings. Look at gross margin, incentive levels as a share of price, net new orders and cancellation rates in each quarterly report.
5. Local price cuts. Our look at Florida builder price cuts is one example of how stress can show up at the town level before national data.

The bottom line

The creator's core argument holds together as a sequence: higher yields lift mortgage rates, rates weaken demand, builders pay for sales through incentives, and margins and share prices suffer. The valuation comparison to 1990 and 2008-2009 is striking, though it deserves independent confirmation and careful interpretation. Trading below book value signals deep skepticism, not bankruptcy, and it has historically reflected expectations rather than a certain outcome.

For most households, the practical takeaway is simpler. New-home buyers have more bargaining room than they have had in some time, but the best-looking incentive is not always the cheapest deal. Compare total costs, get outside financing quotes and base your decision on your own budget rather than on where a stock ticker sits this week.
