The level of your credit score can affect your mortgage interest rate, loan amount, and even the terms of your credit. In other words, if your credit score is low or your credit utilization rate is high, when purchasing a property valued at HK$4 million or less, you may not be offered an 80% or 90% mortgage by the bank. You may also face higher mortgage interest rates and shorter loan terms. TransUnion recommends that you check your personal credit report at least 3 months before applying for a mortgage to be well-prepared.
