Bitesize: How 20-somethings are getting onto the housing ladder in London

Sachin Galaiya.

There are two ways people can make their resources go further when buying a home.

One is to increase the loan-to-value (LTV) ratio and hence increase the amount available to buy a house for a given deposit.

The other is to lengthen the term over which the mortgage is repaid, which increases the size of loan associated with a given level of monthly repayments.

For example, consider someone with £2,000 a month available to spend on a mortgage. At an interest rate of 4.5%, they are able to afford a loan of £360k on a traditional 25-year repayment mortgage.

However, by paying the same monthly amount over 35 years rather than 25 years, the person could borrow £63k more.


The chart shows how in the financial crisis of 2008/9, high LTV (>90%) lending fell sharply as lenders tightened credit criteria, with only a small rise in the proportion of longer mortgages.  But then over the next four years, there were virtually no new high LTV mortgages, but a marked rise in longer term mortgages.  Since 2013, both LTV and term have expanded.

Although this trend towards longer-term mortgages might seem extreme, in countries like Sweden and Japan, ultra-long mortgage terms of up to 100 years are the norm.
