I will be moving into one of the apartments and renting the other apartment and the store.

With zero debt, it can be a great store of value (inflation hedged asset which produces an inflation hedged income stream).

But the basement and the garage (which is supposed to be half for one unit and half for the other) being full I have a problem with.My issue and reason for this post is that the previous owner gave the tenant permission to store his things and there is nothing written in the contract regarding the topic.

You'll get a couple of quotes and you can check the reputation and reviews of the guys actually doing the work instead of getting whoever shows up that day for the big box stores 

I’d get new cabinets, tops, and appliances.At my store, I would figure maybe $2,000-5,000 for new cabinets depending on what you do, $1,500-3,000 for stone tops, and $2,000 for a stainless appliance package.

Usually they are listed on a big board right inside the entrance to the store.

But we really need to get away from Cincinnati and start fresh in a new place. 

A few things I would focus on for your rental is, convenience, does it have high walking score neighborhoods and cater to grocery stores, food, bar, major attractions, etc.

I am fresh out of high school.

Buy in volume, if possible and store in your warehouse or off site facility (when you get to this stage).
