I appreciate the sentiment, but your tenants might have rights that you don't know about. These may vary depending on your locale, and may include restrictions on evictions of tenants who don't have written leases.
This was the document I used to shape my thinking and since I have more than 5 units (8 units total) I'm inspected by my town officials every 2 years to assure the livability.
I see the whole relationship as reciprocal and hope to avoid evictions. I do no credit checks and I do my own internet research. I place a lot of value on the personal interactions and so far I have had good fortune.
