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.

How it works:

  • No capital raising is permitted
  • Aimed at maintaining existing borrowing levels

Fixed rate 5 years or more The higher of 4.5% or product pay rate +1%
