Is NIC mandatory for landlord with more than 1 property

Hi Officer, I have 3 questions on the above topic: 1) Does NI class 2 or 4 become mandatory for landlord with more than 1 property, when the total rental income for the 2 properties at 18,000 per year? 2) Does it make any different if being the landlord is his main job? or what if he gets an employment later? 3) NI calculation in Self Assessment comes after Self-employment section. If Rental Income needs to pay NI, should I put the rental income in Self-Employment Section and register the income as a self-employed business, OR remain in UK Land and Property Section? Thanks

Hi,
We would usually say that in order for a property owner to be gainfully employed for self-employed NI contribution purposes, their property management activities must extend beyond those generally associated with being a landlord.
You can see guidance here:
NIM74250 - Class 2 National Insurance contributions: special cases: property and investment income
