With interest rates so high and house prices stagnating or even dropping in some areas, is now still a good time to get into buy-to-let, or am I better off just putting my cash into a FTSE global tracker for less hassle?
Quick Answer
Despite high interest rates (4.75% Bank of England base rate) and stagnating house prices, buy-to-let can still be viable for long-term investors focused on capital appreciation and rental income, especially through strategies like BRRR. Diversification or alternative investments like FTSE global trackers offer different risk-reward profiles.
## Understanding Buy-to-Let Viability in Current Markets
Investing in buy-to-let (BTL) property in December 2025 requires careful analysis of current market conditions, including interest rates and house price movements. The Bank of England base rate is currently 4.75%, which translates to typical BTL mortgage rates ranging from 5.0-6.5% for a two-year fixed term. Despite these elevated borrowing costs, BTL remains a strategy for building wealth through both capital appreciation and rental income over the long term. A property generating £1,000 in monthly rent could see approximately £500-£650 of that rent directed to mortgage interest payments alone, before other outgoings.
While house price growth has indeed slowed, and even reversed in some localized markets, investment decisions should focus on long-term trends rather than short-term fluctuations. Property remains a tangible asset, and the UK housing supply shortage continues to underpin its value over decades. Strategies like 'Buy, Refurbish, Refinance, Rent' (BRRR) can still generate returns by adding value to properties, regardless of the broader market, allowing for increased rents and equity extraction. A renovation costing £15,000 that increases a property's value by £30,000 and the rent by £150 per month can significantly improve cash flow and equity.
## Potential Downsides and Risks to Consider
Several factors can make BTL less attractive for some investors compared to alternative options like a FTSE global tracker. High mortgage interest rates directly impact cash flow, as Section 24 means individual landlords cannot deduct mortgage interest against rental income for tax purposes. An investor with a £150,000 interest-only mortgage at 5.5% will pay £8,250 annually in interest, which is treated as a finance cost allowance credit rather than a direct deduction, potentially pushing landlords into higher tax brackets for other gains. This financial pressure can erode rental yields, sometimes leading to marginally cashflow-positive or even negative positions in the initial years, requiring investors to have sufficient reserves.
Regulatory changes and increasing costs also present challenges. The additional dwelling Stamp Duty Land Tax (SDLT) surcharge is 5% from April 2025, adding a significant upfront cost. For a £200,000 BTL purchase, the SDLT due would be £10,000, plus the standard band rates. Upcoming legislation like the Renters' Rights Bill, which abolishes Section 21, and Awaab's Law requiring prompt action on damp/mould, increases landlord responsibilities and potential costs. Capital Gains Tax (CGT) on residential property is 18% for basic rate taxpayers and 24% for higher/additional rate taxpayers, with an annual exempt amount of only £3,000, making significant profits taxable. This contrasts with a global tracker, where tax treatment may involve different rates or allowances, such as ISA wrappers for tax-free growth, and typically requires less active management. Investing in the stock market avoids the complexities of HMO licensing, minimum room sizes, and EPC regulations associated with property.
## Investor Rule of Thumb
Buy-to-let is a long-term strategy where active management decisions and intrinsic property value add can outperform passive investments, but only if the chosen asset and strategy align with current market costs and regulatory demands.
## What This Means For You
While a FTSE global tracker offers diversification and passive income without property management complexities, BTL can still deliver superior returns for those willing to engage. Most landlords don't lose money because of market conditions alone, they lose money because they enter without a deep understanding of financing, taxation, and their specific market.

Steven's Take
The question of BTL versus a global tracker isn't about one being inherently 'better,' but about aligning with your investment goals, risk tolerance, and time commitment. Property, especially well-chosen BTL, can offer greater control and the ability to force appreciation through renovation. While mortgage rates are higher now, this can also mean less competition for properties, creating buying opportunities. My own portfolio was built under £20k of my own cash by using strategies like the BRRR model to mitigate higher interest rates and add value. A FTSE tracker offers liquidity and passive growth, but it won't allow you to force value or generate rental income to cover holding costs. It's about 'active' versus 'passive' wealth building.
What You Can Do Next
1. Calculate potential BTL cash flow: Use current BTL mortgage rates (5.0-6.5%) and the 125% rental coverage at 5.5% notional rate stress test (ICR) to assess affordability for potential properties. Factor in Section 24 for tax implications.
2. Research local market conditions: Investigate specific areas for rental demand and capital growth prospects. Look at average rental yields, property price changes, and tenant demographic trends.
3. Understand all upfront and ongoing costs: Total purchase costs include the 5% additional dwelling SDLT surcharge (e.g., £10,000 on a £200,000 property), legal fees, and renovation budgets. Account for ongoing costs like insurance, maintenance, and potential void periods.
4. Review a FTSE global tracker: Understand the fees, historical performance, and tax implications (e.g., ISA benefits) of a global tracker by visiting platforms like Vanguard or Hargreaves Lansdown. Compare the hassle factor and liquidity with BTL.
5. Consult with professionals: Speak to a mortgage broker specializing in buy-to-let and a property tax accountant to understand the specific financial implications for your individual circumstances.
