What should I keep in mind if I am a first-time buyer in the UK residential property?

To purchase the best possible location within your budget.
Be aware of the number of years remaining on the property – generally, a longer lease (90 years and above) allows the property to be mortgaged.
Be aware of mortgage financing options if you need one – banks in Hong Kong will lend up to 75% of the purchase price.
Be aware of closing costs payable, such as a lawyer for conveyancing and Stamp Duty implications as they vary if you’re a first-time buyer or second-time buyer (the UK or anywhere else in the world)
