Are CHL's new 75% LTV tracker mortgages competitive for buy-to-let investors?
Quick Answer
CHL's 75% LTV tracker mortgages are competitive for buy-to-let investors depending on risk tolerance and market outlook, with rates typically mirroring the broader BTL tracker market.
## Understanding the Competitiveness of Tracker Mortgages
Tracker mortgages, including CHL's new 75% LTV offerings, derive their interest rate from the Bank of England base rate, plus a set margin. As of December 2025, the Bank of England base rate stands at 4.75%. This means a tracker mortgage could be priced at, for example, base rate plus 0.75%, resulting in an initial rate of 5.5%. These products are competitive for investors who anticipate a stable or falling base rate, benefiting from potential payment reductions, offering flexibility that fixed rates do not. Tracking offerings may be particularly appealing given the typical BTL fixed rates range from 5.5% to 6.0% for 5-year terms.
## Potential Downsides of Tracker Mortgages for Investors
While tracker mortgages offer flexibility, they also introduce interest rate risk. If the Bank of England base rate increases, the mortgage payments will rise, directly impacting an investor's cash flow. For instance, an increase of 0.25% in the base rate on a £150,000 tracker mortgage at 75% LTV would increase monthly interest payments by approximately £31.25. This volatility can make financial planning challenging, especially when considering the 125% rental coverage stress test at a notional rate of 5.5%, which ensures the property's rental income can support the mortgage payments. Higher interest rates can reduce an investor's net rental income, affecting profitability and cash reserves set aside for property maintenance or void periods. Investors should meticulously review affordability, considering their ability to absorb potential rate increases when considering such products. Furthermore, exit fees and associated product fees should be factored into total cost comparisons.
## Investor Rule of Thumb
Evaluate tracker mortgages by comparing the current full cost (rate + fees) to fixed-rate alternatives, then stress-test cash flow against potential Bank of England base rate increases to ensure sustained profitability and liquidity.
## What This Means For You
Considering CHL's new 75% LTV tracker mortgages means carefully assessing your risk appetite against the current economic outlook. If you believe the base rate is at its peak or will fall, a tracker could offer lower payments over time. However, if rates continue to climb, your borrowing costs will increase, impacting profitability. Analysing these scenarios and how they fit into your overall property strategy is exactly what we dissect within Property Legacy Education.
### Comparing Tracker Competitiveness for Buy-to-Let
* **Bank of England Base Rate:** Currently 4.75%, this dictates the base of the tracker rate. Investors need to monitor announcements closely.
* **Lender Margin:** CHL's specific margin over the base rate determines the final interest rate. A margin of 0.75% would mean a current rate of 5.5%.
* **Product Fees:** Initial arrangement fees can range from 0% to 2% of the loan amount, significantly affecting the overall cost. A 2% fee on a £150,000 loan adds £3,000 upfront.
* **Early Repayment Charges (ERCs):** Some tracker mortgages still carry ERCs, which can penalise investors if they refinance or sell within a defined period.
* **Stress Test Impact:** The standard BTL stress test of 125% rental coverage at a 5.5% notional rate is applied. For example, a monthly interest payment of £687.50 on a £150,000 mortgage would require a minimum rent of £859.38.
### Situations Where Trackers Might Be Less Suitable
* **Interest Rate Sensitivity:** Investors who cannot absorb payment increases from rate rises should avoid trackers.
* **Long-Term Cash Flow Certainty:** If stable, predictable monthly outgoings are crucial for financial planning, fixed rates are generally preferred.
* **Market Volatility Fears:** In periods of expected economic instability or inflation, interest rates are more likely to rise.
* **Refinancing Objectives:** If aiming to hold a property for less than two years, the potential savings from a tracker are often outweighed by initial fees and remarketing costs.
* **Current Debt Burden:** For investors with a high loan-to-value ratio or marginal cash flow, any rate increase could quickly turn a profitable property into a cash drain. For example, a 0.5% rate increase on a £200,000 mortgage at 75% LTV adds £83/month to the payment.
Steven's Take
CHL introducing new 75% LTV tracker mortgages is a market signal. For seasoned investors, trackability of the base rate could present an opportunity if you're confident the base rate has peaked or will decline. Given the Bank of England base rate is 4.75% and BTL fixed rates are still high, a well-managed tracker could offer better value over the short to medium term. However, always run your numbers against potential rate increases. Your cash flow needs to be robust enough to handle the 125% rental coverage and a rising interest charge. Don't be swayed by headline rates; look at the full cost including fees.
