Market analysis - to know the market value.
Advertise on Craigslist and all real restate sites that allow owner advertising.
After finding good perspective tenants, have them fill out the tenant application and run their credit reports. Check local and state laws for landlord tenant responsibilities.
Have an attorney create lease.
Or, work with a great realtor to make sure you have everything done legally and easier for you.
Hope this helps,
