As property prices have been steadily increasing for many years, it has become more difficult to make buy to let mortgages fit the lenders criteria. The particular criteria that most investors try to honour is having a realistic and achievable rental 25% higher than the mortgage payment on any particular property. There are 3 prime factors affecting this criteria



The property value. Clearly, the higher the value of the property, the more money it will cost per month to service the mortgage.

The achievable rent. This varies considerably across the UK, influenced by the demand and the ability of the tenant to pay

The interest rate. Clearly, the lower interest rates make purchasing buy to let properties more achievable, because the monthly mortgage costs are less, therefore the rental requirement is less.





For 5 years the interest rates have been historically low, meaning that it was not too difficult to make the monthly rent fit the criteria. Over the last 5 years the UK has witnessed steady growth in property prices, which has been gradually making the achievement of a rent income of 25% more than the mortgage cost increasingly difficult to achieve. To compound an already difficult set of circumstances with rising property prices, and rentals not rising so quickly, we have also experienced 5 Bank of England base rate increases.



It has been possible to overcome these increasingly difficult conditions as a result of many lenders holding down their mortgage rates on a wide selection of mortgage products. As we all expected with the UK base rate now 5.75% and many buy to let mortgage products still available below 5%, it was inevitable that the lenders would start raising their mortgage rates. Since the last Bank of England base rate increase to 5.75%, we have seen almost all of the buy to let mortgage providers swift to increase their rates. As I write there are only 3 mortgages currently offered below 5%.



With all 3 factors now working against the investor, this will inevitably mean it will become very difficult and increasingly impossible to make the standard 85% loan to value mortgage stack up, particularly when there is total dependency on rental income. The consequence will be more ’affordability’ buy to let mortgages, this is were the investors personal income can be included in the rental calculation. We will probably see over the course of the next 2 - 3 months see builders and private sellers reducing their prices to a level where the buy to let mortgage calculations fit.
