Furnished Holiday Lets

LLF

I've just taken on a new client (handover from previous accountants) who has 5 holiday cottages. Over the winter they let 3 of the cottages out on short term tenancies of 6 months. The cottages therefore were not available for 210 days but did still meet the 105 days during the 6 months they were available. Due to the long term lets exceeding the 155 days does this automatically mean the income for the year needs to be treated as property income and balancing charges paid on capital allowances claimed? I have never had this issue with an FHL before and I am questioning myself so any help appreciated!
