I am also not harmed because the deposit on the property allows me to make any mortgage payment on time...and my tenants have said, "You've been good to us with the late payments," when they have offered to repair small things, etc, so I know they do not take it for granted.

Your partner wont necessarily benefit from accelerated depreciation, but then again, it wont harm him either.

Also their landscaping may be a factor in creating run off that effects my basement/drainage problems.then you should survey it and make a determination right now its just speculation.. its your responsibility if you feel this issue or landscaping is harming your property.. 

Though I don't think the other posters meant any harm, it does show that you are willing to 'go to war' when provoked.

@Adam Hershman Because all of your posts have terrible grammar and punctuation, little substance, and even less actual information.

I'm connected with someone at a local substance abuse treatment center that does all the placement of tenants.

My roommate agreement specified things like: furnished or unfurnished, maximum occupancy- limiting number of overnight guests as it's bills paid roommate living, if it's co-ed or single sex, no smoking vaping e-cigs or substances on the property, cleaning chores/expectations, no underage drinking, pet rules, what utilities are included up to what limits and what utilities aren't included, etc.Require a security deposit from each roommate, even if small.Get a locking thermostat cover; set utility allowances so people won't take advantage of "all bills paid" rooms and have the daughter/master tenant or whoever is paying the utility bills be the person who sets the utilities.

I don't think it's unreasonable to have someone visit for a few days - an extra car (motorcycle) parked in the area isn't going to do anyone any harm. 

Meaning I don't care at all how someone else spends their money as long as it doesn't generally harm me or the greater good.

The law has a general principle called "substance over form."
