Entrepreneur's Relief

Dear Sir

I am having an issue regarding Entrepreneur relief. Question is as follows:

On 30 June 2018, Michael sold a business that he had run as a sole trader since 1 Jan 2014. He realised the following gains and losses on the chargeable assets of the business:

Goodwill 60,000.

Freehold Property 64,000

Storage Unit (13,000)

The Goodwill has been built up since 1 Jan 2014. The Freehold property had been acquired for 6 months prior to the date of disposal and the storage unit had been acquired for on 1 June 2015.

Question:

What is the net chargeable gain on the disposal of the sole trader business on 30 June 2018 that qualifies for entrepreneur relief?

Answer is:

Disposal of business:

Goodwill 60,000
Freehold 64,000
Storage (13,000)
Net ER=111,000

but in my notes its written Assets must have been owned for 1 year minimum prior to the date of disposal, then how come the freehold property is included in the gains qualifying for ER as it has been acquired 6 months prior to disposal.

Please help
