I manage a property with multiple retail stores, but I have a grocery store that needs work done on it.

They make ordering items from different companies easy, and you get discounts from each store that has partnered with them. 

Just clearly state that you supply a starter supply of listed items and you should be fine.

You're wasting hours of your time driving and walking around stores looking for the right lights to fit in your project when you should be looking for more deals.2.

We forbid TV mounts, shelves, or items that require bolts, anchors, screws, or large nails.

On June 7th, we sent an itemized list of deductions via text; he responded on June 8th, disagreeing and threatening legal action.

In my area (near the beach) its mostly families and they want cabanas, baby items, chairs, coolers etc that we do not provide but I have a local vendor that delivers and picks up these items and charges a few dollars per day for each item, and give me a 20% referral. 

Clothing- buy at the second hand store.  

Quote from @Brendan Jones: For the homes, and or properties that you will use as a primary or a rental property one big thing I look for is infrastructure in the area, extrinsic value (I.e. hospitals in the area, schools, and job market), and the last thing is creature comforts for people (I.e. is a store to get groceries 1 hour away or 2 minutes away).

You may want to look at small independent stores.
