If this is an unfurnished rental with a three year tenancy agreement,
If the 3 year tenancy agreement was to end in January 2016,
You could terminate the agreement ONLY by sending a registered letter delivered to the tenant 6 months before the anniversary date of the tenancy agreement (if it was in January, your letter should have been sent in June 2015)
Besides the notice to quit must be motivated by one of the three reasons below (which must be clearly stated in the letter:
- you wish to sell the place
- you wish to live in the place
- you have a proven legitimate reason not to renew the lease (unpaid rent, trouble caused by the tenant,...)
From what you write above your notice to quit (even if motivated by one of the above) was served too late to prevent the renewal of the lease in January 2016.
You can only force him out if he does not pay his rent and if you obtain a court order. But proceedings can take time.
