If you’re asking who can help me get a buy to let mortgage in Scotland or London with the best rates, you are already asking the right question.
In buy to let, the lowest rate advertised online is often not the rate you can actually secure.
That is because buy to let mortgages are policy driven, not just price driven. Approval depends on structure, lender selection, and long-term planning, not headline figures.
This guide explains how buy to let mortgages really work, why rates vary so widely, and who genuinely adds value for landlords in Scotland and London.
A buy to let mortgage is not assessed primarily on your personal income.
Lenders focus instead on:
• Expected rental income
• Property type and location
• Loan to value
• Landlord experience
• Wider financial profile
This is why landlords often experience:
• One lender saying yes
• Another declining the same case
• Comparison sites giving conflicting results
Buy to let decisions are driven by lender policy, not just affordability or rate tables.
The best buy to let mortgage is not always the lowest headline rate.
A strong buy to let deal balances:
• Interest rate
• Fees
• Rental stress testing rules
• Income top slicing options
• Flexibility for remortgaging and portfolio growth
A cheaper rate with restrictive criteria can cost more long term if it:
• Limits borrowing
• Fails stress tests
• Blocks future expansion
This is why buy to let mortgage advice in Scotland and London must look beyond rate comparison.
In Scotland, lenders pay close attention to:
• Home Report valuations
• Local rental demand
• Short term let restrictions
• Property type and location
Cities such as Glasgow, Edinburgh, and Ayrshire towns each carry different lender risk profiles.
Some lenders actively favour Scottish buy to let. Others quietly restrict it. Knowing the difference is critical.
London buy to let lending is assessed more cautiously.
Lenders focus heavily on:
• Rental yield relative to property value
• Interest Coverage Ratio
• Tax position
• Existing portfolio exposure
Even high earning landlords can be restricted if:
• Rental yield is low
• Stress tests fail
• Existing borrowing skews affordability
This is why many London landlords struggle with high street lenders.
Most buy to let lenders apply an Interest Coverage Ratio.
Typical requirements include:
• Rent covering 125% to 145% of mortgage payments
• Stress testing at a higher notional rate
• Higher coverage for higher rate taxpayers
A broker who understands:
• Lower stress lenders
• Five year fixed stress test rules
• Income top slicing options
can be the difference between approval and decline.
This links closely with buy to let affordability planning.
Limited company buy to let mortgages are increasingly common.
They can offer:
• Tax efficiency
• Easier portfolio expansion
• Access to specialist lenders
However:
• Rates can appear higher
• Fees vary significantly
• Lender criteria differs widely
Comparison sites rarely show:
• Director experience weighting
• SPV specific lenders
• Long term remortgage flexibility
This is where specialist limited company buy to let advice becomes essential.
Yes, but lender choice is limited.
Some lenders:
• Avoid first time landlords
• Require existing homeowner status
• Demand higher deposits
Others actively support:
• New landlords
• Small portfolios
• First time buy to let investors
Finding them is not about searching harder. It is about knowing the market.
The honest answer is not:
• Estate agents
• Comparison websites
• Single lender banks
• Generic mortgage advisers
The most effective support comes from a whole of market mortgage broker with buy to let expertise, specifically one who:
• Understands Scotland and London lending differences
• Accesses specialist buy to let lenders
• Structures rental stress tests correctly
• Plans for future borrowing, not just one deal

They assist with:
• First time buy to let purchases
• Portfolio landlords
• Limited company structures
• Buy to let remortgages
• Strategic lender selection
Rather than chasing headline rates, the focus is on approval, sustainability, and future flexibility.
Common errors include:
• Applying directly to one lender
• Assuming the cheapest rate is the best deal
• Ignoring rental stress testing
• Failing to plan future remortgages
• Using residential advisers for investment property
Each of these can restrict borrowing or cost thousands over time.
Rates vary daily. The most competitive deals usually come from specialist lenders accessed through whole of market brokers.
Typically 25%, sometimes higher depending on lender and structure.
Yes, though lender choice is narrower and guidance is important.
Often slightly, but tax efficiency and flexibility can offset this.
Yes, especially where rental stress tests fall short.
It can be due to yield and stress testing, but solutions exist with the right lenders.
