How to screen the tenant.  

Due to the size of these stores it makes it very difficult to rent these locations and in most centers you have to divide the space which requires significant modifications to hvac, electrical, plumbing and storefronts.While this doesn’t answer the questions gives things to consider if buying one.

You didn't say what size, but I'm assuming a basic two car garage, 20 feet by 20 ft roughly?

Property Details: Property Type: 6-Unit Apartment Building Building Area: 4,500 square feet Lot Size: 3,050 square feet Depreciable Basis: $1,000,000 Placed in Service: July 2021 Results from Cost Segregation Study: The study identified various components within the property that qualified for accelerated depreciation, leading to substantial deductions in the first year.

Quote from @Roger Garner: I don't have any recommendations, but I can provide you a guide for screening and selecting a quality PM.

Patio screen door has many holes - replaced with new screen.10.

You need to search for properties near your subject property deal that look like and have the same size as your end result aka a comp aka a comparable.Any quality agent can run your comparable market analysis (CMA), and over time, with practice, you can run your own comps. 

If the new tenant passes your screening criteria, rent to her. 

A couple of months ago, a screen popped up forcing me to pay a fee in order to gain access to my account.

I'm not saying you actually violated any laws or committed any human rights violations, but this is exactly why it's vital to have an objective, documented screening process and publish your criteria on every advertisement for the property that you put out there.
