Buy-to-let mortgages are a core tool for property investors building or refinancing portfolios. They differ from standard residential mortgages as lenders assess both the property’s rental income and the investor’s broader financial position. Buy-to-let finance can be structured for single properties, HMOs, multi-unit blocks, or entire portfolios.
At EAS Finance we know that not every landlord’s situation is the same. Some want the lowest monthly cost, some need the maximum borrowing possible, and others value flexibility above all. The type of product you choose – fixed, tracker, or a mix – makes a real difference to both what you can borrow and what it will cost you over time.

Tracker Mortgages
Tracker Mortgages
The rate moves in line with the Bank of England base rate, plus a margin (e.g. Base + 2%)
Payments can go up or down depending on rate changes
Trackers are usually tested at a high stress rate (around 7%), which reduces borrowing capacity
They often come with lower early repayment charges, making it easier to refinance or sell more easily . Best for: landlords who don’t need the biggest loan but want flexibility and potentially lower costs
Standard Variable Rate (SVR)
Standard Variable Rate (SVR)
When your initial deal ends, your mortgage usually moves onto the lender’s SVR
These rates are typically much higher than fixed or tracker products (often 7%+)
It’s rarely wise to remain on an SVR – refinancing before you reach it is key
Stress Testing – How Lenders Decide the Loan Size
Stress Testing – How Lenders Decide the Loan Size
Lenders don’t simply test affordability against the actual mortgage payment. They apply a stress rate to make sure the loan is affordable even if interest rates rise. The required level of rental cover depends on who is borrowing and their tax position.
Note: These numbers are just worked examples to show the process. They aren’t real mortgage offers. Actual loan amounts depend on the lender, the product chosen, and your own circumstances.

For Individuals:
For Individuals:
Basic rate taxpayers (20%) – rent must cover at least 125% of stressed interest
Higher rate taxpayers (40–45%) – rent must cover at least 145% of stressed interest
Example – Higher Rate Individual
Example – Higher Rate Individual
Property value: £400,000
Monthly rent: £1,500
ICR (Interest Coverage Ratio) requirement: 145%
Stress rate: 5.5%
LTV cap: 75%
Step 1 – Rent ÷ ICR requirement £1,500 ÷ 1.45 = £1,034 (monthly interest allowed)
Step 2 – Translate into maximum loan at 5.5% stress £1,034 ÷ (0.055 ÷ 12) = £226,000
Step 3 – Apply the LTV cap 0.75 × £400,000 = £300,000
Result:
Maximum loan = £226,000 (lower of Step 2 and Step 3)
For Limited Companies / SPVs (Special Purpose Vehicles)
For Limited Companies / SPVs (Special Purpose Vehicles)
SPVs are treated as corporate borrowers, not taxed at personal income tax rates.
Lenders usually apply a lower requirement of 125% ICR.
Example – SPV
Example – SPV
Property value: £400,000
Monthly rent: £1,500
ICR requirement: 125%
Stress rate: 5.5%
LTV cap: 75%
Step 1 – Rent ÷ ICR requirement £1,500 ÷ 1.25 = £1,200 (monthly interest allowed)
Step 2 – Translate into maximum loan at 5.5% stress £1,200 ÷ (0.055 ÷ 12) = £262,000
Step 3 – Apply the LTV cap 0.75 × £400,000 = £300,000
Result:
Maximum loan = £262,000
For Five-Year Fixed Mortgages
For Five-Year Fixed Mortgages
Under rules set by the Prudential Regulation Authority (PRA), lenders may stress test a five-year fixed mortgage at the actual pay rate instead of 5.5% or 7%. This usually increases the maximum loan.
Example – Five-Year Fix at 4.9%
Example – Five-Year Fix at 4.9%
Property value: £400,000
Monthly rent: £1,500
ICR requirement: 145% (individual)
Stress rate: 4.9% (pay rate)
LTV cap: 75%
Step 1 – Rent ÷ ICR requirement £1,500 ÷ 1.45 = £1,034 (monthly interest allowed)
Step 2 – Translate into maximum loan at 4.9% stress £1,034 ÷ (0.049 ÷ 12) = £253,000
Step 3 – Apply the LTV cap 0.75 × £400,000 = £300,000
Result:
Maximum loan = £253,000
