Finding the best buy to let mortgage rates is not about chasing the lowest headline interest rate. It is about matching your investment strategy to the right lender, structure, and long term plan.
Buy to let mortgages are assessed very differently from residential borrowing. The wrong lender choice can restrict portfolio growth, limit future borrowing, or increase tax exposure.
Pelican Finance Limited helps landlords across Scotland and London secure buy to let mortgages that support sustainable investment, not short term wins.
The best buy to let mortgage is one that balances:
• Interest rate
• Product fees
• Rental stress testing
• Flexibility for future borrowing
• Ability to refinance or expand later
A cheaper rate today can reduce borrowing power tomorrow if the lender applies restrictive stress tests or portfolio limits.
This is why buy to let mortgage advice in Scotland and London should always consider the wider strategy.
Most buy to let lenders require rental income to cover the mortgage by a margin known as the Interest Coverage Ratio.
Typical requirements include:
• Rent covering 125% to 145% of mortgage payments
• Calculations based on a higher “stress rate”
• More conservative assumptions for higher rate taxpayers
In London, lenders often apply tougher stress testing due to regulatory pressure and property pricing.
In Scotland, stronger rental yields outside Edinburgh can improve affordability, especially in cities such as Glasgow and surrounding areas.
This difference makes buy to let affordability in Scotland versus London highly lender specific.
Many lenders apply restrictions to:
• First time buyers becoming landlords
• Applicants with no rental history
• Higher loan to value borrowing
However, this does not mean first time landlords cannot secure competitive buy to let mortgages.
Pelican Finance works with lenders that actively support new landlords, provided rental coverage and personal affordability are sound.
This is particularly relevant for those transitioning from residential ownership into first time buy to let investing.
Limited company buy to let mortgages are increasingly popular.
They can:
• Offer tax efficiency depending on circumstances
• Provide access to specialist lenders
• Use different stress testing rules
However, limited company rates and fees differ from personal buy to let mortgages.
Pelican Finance helps clients decide whether limited company buy to let mortgages suit their wider tax and investment position, not just the mortgage rate.
As portfolios grow, lenders assess:
• Total borrowing exposure
• Overall rental coverage across the portfolio
• Loan to value levels
• Portfolio leverage and concentration
Without planning, landlords can hit borrowing ceilings earlier than expected.
Pelican Finance structures borrowing to preserve flexibility and avoid growth restrictions later.
This is key for portfolio landlords in Scotland and London planning long term expansion.
Scotland and London operate very differently for buy to let investors.
• Strong rental yields
• Lower entry prices
• Stable long term tenant demand
• Capital growth focused
• Stricter stress testing
• Larger deposits required
The right lender depends heavily on location, rental yield, and investor objectives.
Estate agent mortgage advice is often:
• Tied to a limited lender panel
• Focused on speed rather than structure
• Not designed for long term portfolio planning
Independent mortgage brokers plan beyond a single transaction and help investors make decisions that support future borrowing.
This is why independent buy to let mortgage advice matters.
Typically 20% to 25%, though this varies by lender.

More regulated, but still viable with the right strategy.
The best buy to let mortgage rate is not the cheapest one today. It is the one that supports your investment plans tomorrow.
