Alert tenants to correct behavior firmly and fairly

[Heather O.]

How would you word a letter to a tenant who is using a screened room as a storage room?

Experiencing tenant with clutter in lanai stacked floor to ceiling seen from the street.

Since I have many tenants, I feel like I should make it a letter that everyone receives and include all current complaints that I have (all were covered in lease - but previous management was lax) plus I want to charge for infractions monthly because all units are severely under-rented:

1. clutter seen from street $150

2. uninsured, unlicensed vehicles stored on property $150

3. pet not on lease $150

4. cigarettes on ground within 30 feet of door $150

5. not replacing filter $50 (send monthly photos as proof)

6. not maintaining property $200

Tips for me?
