Is BRRRR Still Worth It at 7% Mortgage Rates? Our Ten 2026 Strategy Calls, Graded

In December we ranked ten investing strategies for 2026 and told you what each one needed in order to work. Mortgage rates were 6.19% that week.

Last Thursday they were 7.03%.

A strategy ranking is a set of conditions, not a set of favorites. Nine of those conditions still hold at the new price. One of them named its own breaking point in writing, and rates have now crossed it.

Most new investors do not lose deals because they picked the wrong strategy. They lose because nobody told them what their strategy was quietly depending on.

That is the whole issue. Everything below is the working, and the two sections carrying it are The New Range and The 2026 Report Card.

WEEK OF SEPTEMBER 29, 2026

What it signals: The cost of money went up and almost nothing else moved. Prices are still positive, supply is loose but not flooding, and the people who cannot wait are paying to close. That is not a thaw and it is not a crash. It is a market where your financing decides whether a deal works, which is a different market from the one we ranked strategies for in December.

Tripwire check (the thresholds we told you we were watching):

In May we said the base case for 30-year fixed rates through the end of 2027 was 6.25% to 6.75%. Our own rule was that two consecutive prints outside the band meant we revisit it. We got three: 6.76%, 6.95%, 7.03%.

The new range is 6.75% to 7.50%, for as long as the 10-year Treasury holds between 4.75% and 5.50%.

The condition is the part to write down, because it is the part you can check yourself on a Thursday.

Mortgage rates are not set by the Fed. They track the 10-year Treasury plus a spread, and in September that spread ran between 1.81 and 2.01 points, averaging 1.90. The 10-year closed at 5.24% on Sunday. Add the spread and you get the 7% that arrived last week. Run it the other way and the band explains itself: a 10-year at 5.50% implies a 30-year around 7.4%, which is where we put the ceiling.

Here is the line to act on. If the 10-year closes above 5.50%, stop underwriting anything to a rate below 7.5%. You can look that number up in one click, it updates daily instead of weekly, and it moves before your mortgage quote does.

Two honest notes. This band is wider than the one it replaces, which makes it a weaker forecast and a more useful planning number in a month that moved the 10-year 28 basis points in five sessions. And the loudest argument in the trade press this week is whether rates reach 8% or fall back to 6%. We are not calling either one. We are telling you what to underwrite to while the 10-year sits where it sits.

Nine months ago we ranked ten strategies in three tiers. The overall call was that 2026 would be a soft thaw, not a crash and not a moonshot.

Two thirds of that call still describes the market. No crash: sold prices are still positive on every national measure. No moonshot: existing sales are running at 3.98 million with the loosest supply in a decade. The thaw did not arrive. Rates went from 6.19% to 7.03%, the Fed raised instead of cut, and the prime rate that rehab lines float on went to 7.00%. Money got more expensive instead of cheaper, and everything below follows from that.

Four of those need more than a line.

2. House hack and ADU, the best-aged call, for a reason that was not in the original. We ranked it for ADU income. It earned its place on loan access. Builders are advertising an average 3.92% promotional rate (Realtor.com, September 15, 2026), but Fannie Mae makes temporary buydowns ineligible on investment properties and caps investment seller credits at 2% (Selling Guide B2-1.4-04 and B3-4.1-02). Living in the property is currently the only way an ordinary buyer reaches the best financing in this market.

3. Creative finance, right and now crowded. Our condition was slow sales plus rates above 6% creating timeline-sensitive sellers. Rates are 7.03% and resale volume is 3.98 million, so it is fully present, and national outlets began running seller financing as the rate workaround this month. The caveat we owe you: this is the hardest of the three to execute and the one surrounded by the worst advice. Our December entry rule is what separates it from a pitch. DSCR at least 1.20 on the actual terms, clean title, airtight documents. A 3.6% headline rate on a deal that fails those three is not a loophole.

5. BRRRR, the one that named its own breaking point. December's entry said it works only if the refinance DSCR clears at above 6% money. Money is 7.03%, and the prime rate most rehab lines float on went to 7.00% on September 17. That condition is now unmet, which is exactly what the condition was there to tell you. The Deal Lab below shows the same property clearing the rule in December and missing it now. Unless your exit loan is locked before the rehab starts, this is a specialist play this year.

9. Core multifamily, where the direction turned. The December entry priced in flat rents plus concessions as a drag. Rents are still soft at 0.4% below last year, so the drag is real, but vacancy has fallen from a 7.3% peak to 7.0% and new supply is slowing against demand. In metros past their delivery peak this is now a Tier 2 play, not a Tier 3 one.

The score: six held at the new price, two moved tiers in opposite directions, one is ungradable and one aged better than we wrote it. The rate environment went the other way, and the ranking re-sorted around it.

The lesson worth keeping. Every one of those ten rankings was a bet on the rate environment, and only one of them said so out loud. The three that improved all get their edge from somebody else's urgency, which grows when money gets expensive. The one that moved down needed cheap money at the end, and it had no backup when that went away. Rank a strategy by what it needs from rates, not by how good it sounds.

Setup: A rental bought for $180,000 with $45,000 of cosmetic rehab. All-in $225,000, which is 90% of a $250,000 stabilized value, right at the edge of our December rule. It rents for $2,300 a month, $27,600 a year. Operating costs run $10,188 (taxes $3,600, insurance $1,800, maintenance $1,200, management $2,208 at 8% of rent, and a $1,380 vacancy allowance at 5%), leaving $17,412 a year to pay the mortgage. The plan is to refinance at 75% of value, a $187,500 loan, and get your cash back out.

Trap: You underwrote the refinance months before you had to do it.

Reality: At December's 6.19%, that loan covers itself comfortably. At last Thursday's rate it does not.

The payment rose $104.06. Coverage falls to 1.16, and a lender underwriting to 1.20 will not write the loan at $187,500.

Fix: Solve for the loan, not the rate. At 7.03% the largest loan that still clears 1.20 is about $181,198, or 72.5% of value. That leaves $43,802 of your cash in the deal instead of $37,500. The real cost is not $104 a month. It is $6,302 that does not come back out, and that was the money for your next deal. Run the refinance at today's rate plus half a point before you buy, not after the rehab.

Illustrative example with realistic inputs, not a live listing. Point pricing and lender overlays vary.

Rates at 7.03% did not break our strategy ranking. They exposed what each strategy was leaning on. The plays that need someone else to be in a hurry are stronger than they were in December. The play that needed a cheap loan at the finish line is the one to put down this year.

So before you pick a strategy this quarter, ask what it needs from a rate you do not control, and price that at today's number plus half a point.

Not every property is worth your time. The edge is knowing which ones are, and knowing what your plan is quietly betting on.

P.S. Our new rate range is 6.75% to 7.50% while the 10-year Treasury holds 4.75% to 5.50%. Every term in this issue is defined in the investor glossary, which is the page readers open most.
