Your Lender Says the 2027 Loan Limit Is $850,000. Nobody Has the Data Until November 24.

If the loan you need lands between $832,750 and $850,000, a lender will write it as a conforming loan this week. The government number that decides whether it really is one hasn’t been calculated yet.

That isn’t a loophole. It’s a bet, and for once the house is carrying the risk instead of you.

Every November, FHFA sets the baseline conforming loan limit, the biggest loan Fannie Mae and Freddie Mac are allowed to buy. For 2026 it landed at $832,750, up 3.26%, announced on November 25 last year. The formula traces to the Housing and Economic Recovery Act, which requires FHFA to move the baseline “each year to reflect the change in the average U.S. home price.” The input for the 2027 number is third-quarter 2026 prices.

Now go read FHFA’s own release calendar. The quarterly index covering 2026Q3 publishes Tuesday, November 24.

Lenders didn’t wait for it. Pennymac moved its one-unit limit to $850,000 on September 16, effective immediately across all three of its channels, and called itself the first large lender there. Rocket and CrossCountry had already gone to $845,000, a figure twelve lenders now share. CrossCountry sells its version as an “Early Bird Program.”

Twelve lenders landing on the same dollar amount for a number nobody has computed is a neat trick. Pennymac added $5,000 and a press release.

So who’s closer? The last real data is FHFA’s second-quarter index, out August 25: prices up 2.1% over the year, up 0.3% for the quarter, and the June monthly reading flat against May. Run 2.1% on $832,750 and you get about $850,238. Pennymac priced the trend almost exactly. The $845,000 group priced 1.47%, betting the third quarter slowed. Both are guesses about a quarter that hasn’t been measured.

Here’s the catch, and it’s the lender’s catch. A loan above today’s official limit can’t be delivered to Fannie or Freddie yet, so whoever writes it has to fund and hold it until the real number arrives. Once you close, your note rate is your note rate.

What the window is worth to you: $17,250 more loan than the official limit allows, which at 20% down is roughly $21,500 more house, on conforming terms instead of jumbo.

Your call, and a fair one to take. Take it with the pricing in your hand, not in a phone call.

Get the rate and the fees on the early-limit program in writing, then make the same lender quote you a jumbo the same day and set the two side by side. Ask what happens to your loan if FHFA’s November number comes in under theirs, and don’t accept a shrug. If you need $848,000 and your lender stopped at $845,000, call two more before you accept jumbo pricing. The gap between lenders is $5,000 of house right now, and it costs you nothing to ask.

One footnote for the top end. The ceiling in high-cost counties runs at 150% of the baseline, $1,249,125 for 2026. It moves when the baseline moves, so the same November announcement resets that number too.
