I have known John for quite a long time and he has been my tenant for the past 5 years. I can, with confidence, state that he is a very honest and hardworking fellow, who hasn’t caused any trouble to his landlord. He is also very helpful and interactive and can strike up a conversation easily. He never gets into any antisocial or problematic activities and is also very religious. He is most definitely a safe bet, both in terms of timely rental payments, as well as in the maintenance and welfare of my property.
You will be certainly lucky to have him as a tenant.
