Two-year fixed rates below 5%
Moneyfacts’ data also found that the average two-year fixed BTL mortgage rate was 4.98% in June, the first time average pricing had been below 5% since September 2022.

At 80% LTV, the average rate was 5.62%, down from 5.78% in May.
The average rate for a five-year fix across all tiers was 5.29% in June, a slight decline from 5.33% the month before.

BTL landlords still under pressure
Rachel Springall, finance expert at Moneyfactscompare.co.uk, said landlords looking for a new BTL mortgage might be “pleased to see a rise in product availability”.
She added: “Borrowers concerned about interest rates may also find it encouraging to see the average two-year fixed BTL rate has fallen below 5% for the first time since September 2022 and both the two- and five-year fixed rates have fallen for the fourth consecutive month. The average five-year fixed BTL rate is now at its lowest level in over six months, but year-on-year, the rate has not dropped as viciously as its two-year counterpart. Lenders monitor swap rates to gauge future rate expectations, and when they drop, it encourages mortgage rate cuts. Lower BTL rates might create a positive sentiment for new and existing landlords, however, there will be immense pressure on some to turn around a profit in the future.”
Springall continued: “Landlords must ensure their property has a minimum Energy Performance Certificate (EPC) rating of C by 2030 at the latest, according to the government’s latest proposals. This is why a BTL investment might not work for accidental landlords who are not able to fork out the costs to make renovations. Investors typically expect to make better profits if investing in multiple properties, but by the same notion, it can open them to more risk if property prices plummet and they are locked into a mortgage or have no tenant for an extended period of time. Finding the right location to enter the market is essential, so it’s wise to expand property searches across other areas in the country outside of the obvious major cities.
“Landlords coming off a low rate fixed deal and needing to refinance will see increasing rents as the easiest way to boost margins. Landlords will also need to keep in mind the Renters’ Right Bill, which is expected to come into force either later this year or in 2026. The new laws include abolishing Section 21 evictions and fixed-term tenancies, but also new rules on making rent increases. The legislation is designed to protect millions of renters, giving them more security, but understandably this might be the final straw for existing landlords, leading to them exiting the sector. Seeking advice before buying any property, such as the workings of setting up a limited company is essential. It is also vital for prospective investors to weigh up the costs involved in entering the BTL market, such as the minimum 5% surcharge on stamp duty land tax (SDLT). An investment in property is more than aiming for a monthly profit, it’s important to understand the longer-term returns of selling the asset, and the tax implications of selling up.”
