I come across a person who has a commercial strip of 7 stores free and clear worth around 2 Mil.

Depending on the demographics of the area, I've found that Home Depot/Lowes is fine for just about anything going in a regular rental.One must consider return on investment and buying fancy custom cabinets won't yield much if any more rent that box store shaker cabinets, especially in a duplex.Get some decent cabinets and a good countertop and you should be good to go.

My guess is materials from stores like Home Depot or Lowes.

I’ve been down this road before, and I’ve got a couple of tips that might help you out with your address situation.First, head over to your local UPS store and rent a mailbox.

Its handy for me to store maintenance materials, lumber, vanities, applicances, etc, for my other properties.

Because of my brutal impatience we just had an offer accepted for a 5 unit building with 2 store fronts and 3 apartments that all need to be gutted and renovated.

You are correct a popular commercial store adds value to the overall property, but that value is added into the sale price, it doesn't affect the monthly CF/operating return for the landlord.

In doing another quick google search concerning Sherida Heinz Zenger, it wass found that she was fired from her last job as a sales associate for a night end department store in Utah called Nordstroms. 

A kid can steal 50 bucks from a store and gets locked up.

They also give you access to physical office space if needed.Mailbox services like UPS Store and Pak Mail offer mailbox services with a real street address.
