In fact, the properties on either side of the house are commercial - one a house that was converted to a nursery school some years ago, and on the other side, a former gas station that is now major wireless carrier's cell phone store. 

One option is to purchase a new fridge for the tenant (I buy mine at the Sears scratch and dent store because they're often 50%-60% of the price of a new, undamaged fridge). 

I would try a home improvement store.

Some of the larger expenses-Interior/Exterior Paint, Storm shutters for a few of the front large windows, added additional cabinets to one unit, New refrigerator from Dent/Scratch store after old one died, Laundry units that tenant pays +$50/mo for etc.

I use these tools for my own house so rather than have them clutter up my garage they all are stored nicely in my trailer.

Something I do to help get a tenant out when there lease it up is I will get free boxes from the local liquor and hardware stores and drop them off at the door.

Do they say that about Bankers, Grocery Store Owners, Doctors (well maybe doctors..bad example) plumbers, etc?

It's no better than working at the Verizon store, in fact it's probably worse. 

Again, the BiggerPockets store has some books for this or you can learn by watching podcasts, reading blogs, and interacting on the forum.

I received my first check this month and felt like a kid in a candy store!
