Tenant Compliance and enforcement during tenancy.

[Gabe N.]

Hi
I am sorry for asking this topic if it has been covered already.
I have an asset that is a single family home in an upper scale neighborhood.
The current tenants are a family of 4.

In my lease agreement I have spelled out that the tenant is responsible for pulling weeds and raking up the leaves. 
I also have a clause about doing quarterly inspections inside and outside of the property.

In my most recent inspection I noticed that the tenants are letting the weeds grow out of control.
I also noticed that they made a hole in a wall due to slamming the door against the wall.

I asked them to take care of the weeds and explained that letting the weeds grow out of control is a violation of the lease agreement and the HOA rules. The HoA can issue a citation for the yard being full of weeds and that they would be responsible for paying the fines.
I also mentioned about the hole in the wall. However so far i just got lip service and no action. Their lease agreement expires in 11 months.

what is the best approach to motivate the tenants to address these two issues and be as civil as possible about the situation?
