Landbay tracker mortgage range adds 11 products and cuts rates

Landbay launched 11 new buy-to-let tracker mortgage products on 23 September 2026 and cut rates on selected existing trackers by up to 15bps (0.15 percentage points), according to Mortgage Solutions. The new deals sit across its Core, Premier, small HMO (house in multiple occupation) and product transfer ranges. Here's the angle: the headline rate is not the most interesting part of this launch. The stress test is.

Where is the opportunity in the Landbay tracker launch?

A tracker mortgage moves with bank base rate (BBR), the Bank of England's Bank Rate, plus a fixed margin. Landbay's new Premier Like for Like two-year tracker at 75% LTV (loan to value) starts from BBR plus 0.34%, according to Mortgage Soup. The Premier Like for Like AVM version (valued by an automated valuation model rather than a surveyor) starts from BBR plus 1.34%. Both come without early repayment charges.

Now the part worth watching. Both Like for Like products use a reduced stress rate of 4.5% or the pay rate for landlords refinancing without additional borrowing (Mortgage Soup). A stress rate is the notional rate a lender uses to check your rent covers the mortgage. A lower one can lift the loan a given rent will support.

Landbay's sales and distribution director, Rob Stanton, put it plainly in The Intermediary: "affordability can be just as important as headline rate when landlords come to refinance." If you hold a property that fails a stress test at a higher rate, you can model the difference with our free BTL stress test calculator. The coverage does not say what rental cover ratio applies, so check that with a broker.

What do the rates look like with Bank Rate at 3.75%?

The Bank of England's Monetary Policy Committee (MPC) voted 6-3 to maintain Bank Rate at 3.75%. That was at its meeting ending on 16 September 2026, according to the September 2026 Monetary Policy Summary. On that rate, BBR plus 0.34% works out at 4.09%.

Other pay rates on the same basis, using margins from Mortgage Soup:

• Core two-year tracker with no early repayment charges, 65% LTV (existing, after the cut): BBR plus 0.29%, so 4.04%

• Core two-year tracker with no early repayment charges, 75% LTV (existing, after the cut): BBR plus 0.49%, so 4.24%

• Premier small HMO two-year tracker, 75% LTV (new): BBR plus 0.64%, so 4.39%

• Specialist small HMO and small MUFB (multi-unit freehold block) trackers, 75% LTV (existing, after the cut): BBR plus 1.54%, so 5.29%

These are starting rates. The trade coverage does not give arrangement fees, so the true cost of each deal is not yet clear. For HMO investors weighing the small HMO trackers, our HMO valuation calculator shows how lenders may value the asset at refinance.

What is the risk if Bank Rate moves?

A tracker gives you flexibility, but it also passes rate rises straight through. Three MPC members voted to increase Bank Rate by 0.25 percentage points, to 4%, according to the Bank of England. At that level, the Premier Like for Like product would pay 4.34%.

Here's an illustration, not a quote. On a £200,000 interest-only loan, 4.09% costs about £682 a month. At 4.34% it costs about £723, roughly £42 more each month.

Landbay says it is seeing increased demand for tracker products as fixed rate pricing faces renewed upward pressure (Mortgage Solutions). For me, the lack of early repayment charges is the second thing worth watching. It keeps the exit open if you later want to fix.
