More relaxed mortgage regulation opens the door for some first-time buyers, but it comes with risk.

If you're working towards buying your first home you might feel like everything is stacked against you - but recent changes could help you get a mortgage. It hard to save for a deposit when the cost of living is so high, the average house price is nearly £300,000, external and interest rates on new mortgages are rising. However, a rule change and more flexible lending mean first-time buyers can now borrow up to six, or at the most, seven times what you earn in a year. This means mortgages will be within reach for more people but it is a shift that comes with some risk so here's what you need to know. Reckless mortgage lending was blamed for the financial crisis of 2008, which brought some banks to their knees and saw people lose their homes. In 2014, the business secretary of the time, Vince Cable, said he was appalled that some mortgage providers were lending five times a mortgage applicant's income, suggesting a stable level was up to 3.5 times. But house prices have risen significantly since, outstripping wage rises most of the time. So a bigger loan has become the only option for many potential buyers. Regulation limited how much lenders were able to lend - technically, only 15% of their new mortgages could be at higher than 4.5 times loan-to-income. Many of the big lenders played it very safe meaning they didn't get close to the limit.
