Mr. Tan, a retired Malaysian Chinese who ordinarily resides in Singapore, purchased a residential property in Tai Po for $20,000,000 in July 2017 for investment purpose. Mr. Tan did not own any other residential property in Hong Kong at the time of the purchase. The property was subsequently let to Mr. Chan for 3 years starting from 1 September 2017. The relevant terms of tenancy agreement were extracted below: . . . . . . Monthly rent: $30,000 payable at the beginning of each month Rent free period of one month from 1 September 2017 Initial premium of $60,000, payable on signing the lease agreement Rates of $3,000 per quarter, payable by Mr. Tan to the government Management fees: $1,000 per month payable by the landlord Rental deposit: $60,000 payable on signing the lease agreement. As per the lease agreement, the rental deposit is used to compensate any loss of revenue when the tenant defaults in payment. In October 2017, the property underwent certain repairs for $3,000. The tenant did not deduct the repairs cost from the rental payment. On 1 March 2018, the tenant advised Mr. Tan that he had moved out of the flat due to a water dripping problem, and refused to pay the rent for the month of March. Mr. Tan immediately paid $40,000 to repair the property and fixed the water dripping problem in a week. The tenant moved back into the property on 1 April 2018 and continued to pay the rent from that date. Mr. Tan hired a lawyer to recover the March rental from the tenant and incurred a legal fee of $5,000. On 30 June 2018, the tenant terminated the lease and moved out of the flat. Mr. Tan deducted one month's rental from the rental deposit to compensate for the unpaid March rental and refunded $30,000 to the tenant upon termination of the lease. Since then, the property has been left vacant. Mr. Tan incurred $16,000 per month as mortgage interest. He also paid $15,000 for property agency fee for sourcing the tenant.
