How to stress test your portfolio with Lendlord

When applying for a new mortgage or remortgaging an existing property, many lenders, especially the mainstream lenders will stress test all existing properties to ensure that they fit within certain lending criteria parameters. The purpose for this is to reduce their overall risk and ensure that a portfolio landlord is not overstretched. There are different ways of stress testing a portfolio and that a basic level they will look at an overall loan to value (LTV) not exceeding a certain level. A more detailed and stringent stress test involves an interest cover ratio (ICR).

What is the Interest Cover Ratio (ICR)?

Interest rates are at an all-time low and when lenders look at an existing portfolio they stress test the portfolio using a higher interest rate than most people will be paying. By doing this, they ensure that the rental income will be sufficient to cover future interest rate rises. The vast majority of lenders will use an interest rate of 4.5% to 5.5% and then stress this at a ratio of 125% to 145% of the resulting payment. If these ratios are not met, many lenders will decline the application irrespective of the relevant property perhaps fitting the lender criteria.
