It's more than simply avoiding the possibility of expenses due to  weather or vandalism.Once a property is retrofitted and brought into service, they typically command above market rent, while providing the client/tenant with above market value.Alas, I presume we shall continue to look at the glass from differing perspectives.

I do not have a very commanding presence, and while I talk sternly to tenants if required, I feel like I have no leverage in this situation because the tenants will keep ignoring me unless I "do" something, not just talk.Making matters worse is the fact that they are dirt poor, and my sympathy meter kicks in.  

You could also suggest tenants use command strips, but not every wall is good for these.Can you share your move-out checklist?

The level of workmanship is of a handyman quality level so could certainly use further improving.Below is a list of possible improvements/ upgrades I could make to the unit and I would love any advice as to what improvements have provided the best return on investment in terms of commanding higher rents.

Does the dog listen, does the dog sit on command, etc.

If you can command more rent, then replace, as it will bring in more rent and provide a higher value for the unit. 

Although not ideal for a rental property, it may make your property more marketable and command a higher rent.is it one of those big pools that are just a think lining that you take down in the winter and is not permanent?

I would only do this if the dogs have shown viciousness, have destroyed property, or defecate in unauthorized areas (most service dogs are trained to defecate on command). 

I know I need to take command here....we've been regretting the 2-yr lease for over a year now, lol!

A couple friends told me to go to their commanding officers because they are in the military.
