Homeowners can install proper screening for windows and patios to prevent no-see-ums from entering residences and outdoor areas used for leisure and entertaining.

For things like routine lawn care and preventive maintenance, such as termite protection, the value is the cost. 

I have since found out that other tenants on the park pay for their own monthly maintenance sprayings and have been doing this as a matter of choice since they moved in to make sure they don't get any issues in the first place.I also have 3 SFH and 2 of those tenants (also inherited) have their properties sprayed on a monthly preventative basis.I would be interested to hear how other landlords treat this issue and who's responsibility do you believe it falls upon.

IE special landscaping care to prevent dead grass, forcing the tenant to obey leash laws, requiring copies of shots, and licensing of dogs, forcing tenant to have additional insurance for the dogs that protect you?

This is to prevent the proliferation of rooming houses as rents are so expensive that 3 or 4 people would have to share the rent.

It just sort of hit me in the shower this morning and I don't know the answer.I'm trying to look at preventative maintenance costs over the year, Pest Control might need to be on the list.

We know there were some delays in response and have put in measures to prevent that in the future.

To keep legislators from intervening; to prevent legislation investors will find undesirable.With so many people out there "doing it wrong" and "learning from their mistakes", a point is reached where legislators must step in to protect those who are being hurt: lenders and other money investors as well as tenants and property owners / buyers.Want to curb further tenant-friendly ordinances and other legislation which hurts investors? 

I have a tenant from hell who will go to any length to prevent access to the property. 

Just remember that it will not prevent you from being named in the suit.
