Whether you're a first-time buyer, a second stepper, a homeowner looking to remortgage or a buy-to-let landlord, 2020 is sure to be another rollercoaster ride in the world of mortgages.
After an uncertain time for the property market, tough competition between banks has resulted in cheaper home loans at almost all levels of the market - but you'll need to be savvy to get the best deal.
Here, Which? predicts the mortgage trends we're likely to see in 2020 and explains how you can work them to your advantage.
Here's what we think might happen in the mortgage market for first-time buyers in 2020.
In the meantime, we could see more lenders offering higher income multiples to select groups of first-time buyers, based on either their profession or income.
Five-year fixed-rate deals were huge last year, with cheap rates and economic uncertainty leading buyers and remortgagers to lock in their deals for longer.
However, there's only so far that rates can drop before banks begin to look elsewhere for profits.
Mortgage terms of up to 40 years are becoming more common, and with first-time buyer affordability remaining stretched, it's likely that this trend will continue.
In 2020, we could see more lenders loosen their upper age limits to make longer-term borrowing options available to more that just the youngest first-time buyers.
Last year was great for people who wanted to remortgage, with both two and five-year fixes dropping in cost over the course of the year.
Here are our top three predictions for the remortgaging market in 2020.
The January sales aren't limited to the high street: in the first month of 2019 we saw a host of lenders cut the cost of their fixed-rate deals.
A January sale could be good news for anyone looking to remortgage in the first half of the year, as you'll usually be able to lock in a new rate up to six months before your current deal expires.
When comparing mortgages, ensure you consider upfront fees and early repayment charges, and don't just focus on cheap initial rates.
With mortgage rates likely to remain attractive, we could see more homeowners look to stay put and borrow money for renovations.
Data from UK Finance shows that nearly 18,000 people remortgaged with additional borrowing in September 2019, up 6% on year-on-year.
The current best initial rates of 2.85% at 90% loan-to-value and 4.09% at 95% are unlikely to attract many first-time buyers to fix for a decade, so it would be no surprise to see lenders cut the cost of these deals early in 2020.
10-year fixes can come with high early repayment charges, so weigh up your options before jumping in.
2019 marked another year of increased regulation and dwindling profits for many landlords, but the mortgage market offered a rare bright spot.
Two-year fixes are still attractively priced at many levels, with very little to choose between the best rates at 60% and 75% LTV.
With the final round of cuts set to kick in from April and confusion around the future of no-fault evictions, it's likely we'll see landlords keep their options open by taking out two-year fixes in 2020.
Lenders are competing to offer headline-grabbing rates and cashback deals, but you'll need to be sure they're not giving with one hand and taking away with the other.
But all is not as it seems. Getting £500 or £1,000 cashback might sound like a good thing, but table-topping deals currently come with upfront fees of between £1,495 and £1,995.
When comparing mortgages, ensure sure you look at the overall cost rather than being drawn in by low initial rates or cashback incentives.
In the year to September 2019, the number of new loans granted to buy-to-let purchases fell by 3.5%, and overall lending dropped by 11.1%, according to data from UK Finance.
Remortgaging activity, however, remained steady and made up around 70% of the buy-to-let market.
The current climate of cheap remortgaging rates is a a good time to check whether you're really getting the best deal on your portfolio.
A broker can access hundreds of mortgages that aren't available on the open market and ensure you're getting the right deal.
