Buy-to-let turns 30 with a resilience that challenges the headlines. Policy reform has reshaped ownership structures and shifted investment geographically, yet landlords continue to buy, remortgage and improve properties. Private rental housing quality has improved markedly since 2005, government data shows. The market is not dying. It is evolving, and the professional landlords at its centre are adapting with it.
The evidence says yes. Research by Pegasus Insight, conducted for Paragon Bank, found 86% of landlords reported operating profitable lettings businesses. The proportion experiencing rent arrears fell to its lowest level in the long-running Landlord Trends report. Average gross rental yields exceed 7%, and returns can be greater where landlords target specific property types or areas. HMOs generate average gross yields of 8.9%. Properties in established student markets produce average yields of 7.32%, compared with 6.86% elsewhere. Louisa Sedgwick of Paragon Bank said: 'Landlords continue to prove that buy-to-let represents a sound long-term investment.' The data behind that claim is consistent across arrears, yields and landlord intent alike.
UK Finance figures show that three-month-plus arrears on buy-to-let mortgages have fallen for nine consecutive quarters. They stood at just 0.52% of outstanding mortgages at the end of Q2 2026. Buy-to-let has also consistently outperformed the wider owner-occupier market on arrears over the long term. This aligns with Pegasus Insight data showing the proportion of landlords experiencing rent arrears at its lowest recorded level. The figures challenge the kind of sensationalised headlines that have periodically declared the sector in crisis. Performance across both measures points to a market that, on the evidence available, is functioning well for the professional landlords operating within it.
Analysis of Paragon Bank's own lending data shows average gross rental yields exceed 7%, with HMOs producing 8.9% and student market properties generating 7.32% against 6.86% elsewhere. Paragon Bank's buy-to-let hotspot analysis found that the postcodes attracting the greatest number of mortgage completions sit close to universities or major employers. All generated yields above the wider market average. Landlords are actively targeting these locations. The pattern is consistent: proximity to strong rental demand, whether from students or large workforces, produces above-average returns. Specialist knowledge of these property types and locations is where brokers can add material value to their clients.
UK Finance data shows 43% of mortgaged buy-to-let purchases were completed through limited company structures in 2025, up from just 7.5% in 2018. The phased introduction of Section 24, which restricted mortgage interest tax relief for individual landlords, was one of the key factors behind that growth. As limited company ownership has become more common, understanding the differences between corporate and personal borrowing has become an increasingly important part of the specialist buy-to-let market. The structural shift is substantial. Landlords who moved into corporate ownership did so for tax efficiency, and brokers who could work through the different lending criteria gained a clear advantage in retaining and growing portfolios with their clients.
Landlords withdrew £2.37 billion in equity at remortgage during 2025 to fund property improvements, according to analysis of industry data. Government data from the English Housing Survey shows the proportion of privately rented homes classed as non-decent fell from 47% in 2005 to 21% in 2023. This demonstrates the extent to which mortgage finance is being used to support landlords to remain compliant, increase the value of their assets and provide high-quality homes for renters. While there is still work to be done, the link between privately rented homes and poor quality is more tenuous than some would have you believe. Capital recycled through remortgage is doing real work in the housing stock.
Paragon Bank's analysis of Stamp Duty surcharge data shows a decisive shift northward. In 2015, the south of England accounted for nearly 56% of mortgaged buy-to-let house purchases, while the Midlands and north represented less than 35%. By 2025, the Midlands and north accounted for just over half of purchases and the south's share had fallen to around 38%. The surcharge is not the only reason for that change, but being charged as a proportion of the purchase price and paid upfront, it has acted as a greater barrier to investment in higher-value markets. Yields in northern and midland markets have attracted landlords who would once have looked south.
Sedgwick spoke with buy-to-let customers at Paragon Bank and found that landlords at very different scales, one with a sizeable portfolio, another owning just two properties, both planned to expand. Both managed their lettings businesses more like SMEs than side-hustles. Both were explicit that they value the relative stability of bricks and mortar, viewing buy-to-let as a long-term investment. Sedgwick said: 'Landlords who intend to buy, refinance or improve their properties will continue to need people who understand specialist finance and can apply that knowledge to the particular property, borrower and plan in front of them.' For brokers, that outlook is more useful than any sweeping prediction about the sector's future. Mortgage Introducer's premium specialist reports cover the lending topics shaping professional buy-to-let in 2026.
