As to doing the due diligence, you should be able to find a CPA to give an opinion, Charles is here on BP and I would think that you could have him run the numbers, be sure to pay him to do so, you don't need a CPA in town really since we have all the gadgets we do now.I'm a little worried here too, because you're getting into commercial and sounds like you're brand new to it, which makes me wonder if you might not need a mentor in your area or in the investment area for due diligence.

Most of us blow through hundreds of dollars a month on fancy coffee, eating out, car payments, the latest gadget, fancy clothes, what have you.  

Go go Gadget Copter!

I am not familiar with all the gadgets and I am messing up.

My new little gadget confirmed there was no power going to the hot water heater (Its an electric hot water heater).

Pet deposit of $300 for pets under 25 lbs, Maximum of 2 pets allowed No smoking or vaping allowed on the propertyTenant pays all utilities (gas, electric, water/sewer, garbage, phone/internet)This is a one year leaseAppliances provided are Range, Refrigerator, and Dishwasher.Washer and dryer hookups in the garage allow for tenant to install washer and dryerLawn, landscaping, gutter cleaning and declogging, and exterior maintenance are the tenants responsibilityPest control is tenant responsibility, excluding termites and rodentsRegular HVAC filter changes are tenant responsibilityShall abide by all Rock Creek Community rules & regulations; violations with fines associated with them shall be paid by the tenant and included in monthly rent.No waterbedsClogged toilets & drains, as well as light bulb replacements are tenants responsibilityStorage of personal property shall be at tenants sole risk.

Our current options: 1) a couple that vapes and has a small dog (they say they never vape inside, but that's also what all the vapers I know tell their landlords)2) a couple that has 2 large dogs and a 36 gallon aquarium

Things like,1. management2. building materials to use3. technology gadgets 4. furnishing5. design - extra amenities 

More specific ideas for business that still operate these days: scrubs shop, medical equipment, bikes shop, pet stores, hardware stores, nurseries, beauty supplies, dollar stores, cannabis store (if legal in your state) or CBD products store, vape/smoke shops, doughnut stores, Fitness equipment store, pop-up COVID testing centers.Bonus round:If your location has a big parking lot, you can set up a "movie drive-in" on some nights and have the businesses in the strip serve the food/drinks.

Would you lease a part of your strip center to a head shop (tobacco shop that sells pipes, vapes,  and related items)?
