Interest Cover Ratio & Like-for-Like Remortgages
Explore flexible affordability routes for Buy to Let lending.
Our Buy to Let affordability options include Interest Cover Ratio (ICR), based solely on rental income, and Like-for-Like Remortgages, which use a simplified rental assessment for clients not increasing their loan. These options are tailored to suit a range of client needs, whether they’re expanding their portfolio or simply switching lenders.
Interest Cover Ratio (ICR)
ICR is a method for assessing Buy to Let affordability which relies solely on the rental income from the property.
How it works:
- No minimum income required
- Ability to pay is assessed on rental income (received in GBP)
- Rental income must be at least 145% of the monthly interest due, inclusive of any product fees added to the loan. This is calculated using the relevant stress rate below:
| Product | Stress rate |
| Fixed rate less than 5 years or a variable rate | The higher of 5.5% or product pay rate +2% |
| Fixed rate 5 years or more | The higher of 4.5% or product pay rate +1% |
- All Buy to Let properties must have an EPC rating of A-E (Scotland A-D), or A-C for Energy Efficient mortgages, before the valuation is carried out. In England and Wales, properties listed on the PRS Exemptions Register are also accepted.
Key features:
- Available on both Standard and Energy Efficient Buy to Let mortgages
- Supports purchase and remortgage applications
- Up to 75% Loan to Value (LTV)
- Maximum individual loan of £750,000
- Maximum portfolio size of 3 mortgaged Buy to Let properties per applicant across all lenders, including Bank of Ireland Group.
Best for clients who:
- Have high-yielding rental properties
- Prefer a rental-only affordability route
- Do not wish or need to use personal income in the assessment.
