Are mortgage rates different there?
In some cases, yes. Although most major UK banks offer the same deals on Northern Irish mortgages as they do in the rest of the UK.
However, some of the best mortgage rates in the UK are available in Northern Ireland. But to find them, you need to know where to look. And that requires extensive knowledge of this market.
Fewer mortgage providers lend in Northern Ireland than in other parts of the UK, and some lenders include postcode restrictions as part of their lending criteria.
As such, it can be hard to find a deal that suits your circumstances by using traditional routes such as online comparison sites or going directly to a lender.
Are the rates different for first-time buyers?
Many first-time buyers in Northern Ireland take out mortgages with a low deposit of between 5% and 10%. This creates greater risk for the lender and leads to slightly higher rates.
However, competitive rates are available for those with a clean credit record and good affordability. Government schemes are also available to help first-time buyers in Northern Ireland who are struggling to save for a deposit.

Getting the best rate on a remortgage
Often, when you remortgage, you can access better rates as equity has built up and your loan-to-value (LTV) has reduced.
It can be tempting to simply take the rate your existing lender offers, but much lower rates could be available by scouring the entire Northern Irish remortgage market. And if you employ a broker to do the leg work for you, it needn’t cause you any hassle or stress.
Buy-to-let mortgage rates in Northern Ireland
Buy-to-let interest rates in Northern Ireland are broadly similar to those available across the rest of the UK, although it can be a little more challenging to find a lender in some postcode areas.
Typically, you will need a deposit of at least 25% to get a buy-to-let mortgage in Northern Ireland. With a 25% deposit and a strong application, you should be able to qualify for the most competitive rates available.
