Review your state and local residential tenancy laws. Each state has differing rules for evicting tenants after purchasing a property. Although almost all states require some form of written notice be served, the length of time the notice allows the tenants can vary significantly.
Draft a Notice to Vacate the property, addressed to the tenant. This can be styled in letter form; you may be able to find a sample Notice to Vacate online that you can use as a guide. Being by stating, "This is an official notice to vacate the residential property located at" followed by the property address, city, county and state.
State how long the tenant has to clear his belongings from the property and move out. Include the actual date by which the tenant must vacate. Explain that if the tenant has not vacated the property and cleared his belongings by this time, you will have to obtain a court order to have him forcibly removed, and he may be required to pay rent to you for each day he continued to unlawfully occupy the residence.
Provide your contact information, including your home telephone number, cellular phone number and email address. Invite the tenant to contact you if there any questions or if he would like to discuss the matter further. Sign the bottom of the notice and make two copies. Retain one copy for your records.
Send the original signed notice to the tenant via Certified Mail with signature delivery. Retain the green Certified Mail receipt for your records as proof that the notice was both sent and received.
Follow up after you receive confirmation of the notice being received. Contact the tenant by telephone or in person on the day of or the day prior to the vacate date. If the tenant is uncooperative, unresponsive or states that he will not be leaving the property, your next step should be to obtain a court order for eviction.
