Oh yeah, it opens an artery on them, because the better DOMESTIC economy goes local small business wins. 

So, given you are in a lower end area with lower rents, you need to reserve more money on repairs, maintenance and capex compared to a higher rent area, since that $200 HVAC or plumbing service call is 25% of $800/mo, but 10% of $2,000/mo.  

The new bathroom will be constructed within the existing structure, and while electrical wiring might be needed, plumbing installation is definite.

If a deal doesn't work if you have 3-4 worst case scenarios in plumbing, electrical, etc... then it wasn't purchased well enough to make it worth the time and effort. 

After securing the deal, the buyer made my wife and I go through three-feet deep of snow to "winterize" the house so there wouldn't be any plumbing issues.It was a 2 hour drive there, and a 2 hour drive back.So much time and effort put into it for only $4k...

So I’m in a bit of a bind, I have a duplex I’m house hacking we remodeled entire thing, new hvac, electric panels, electric main, updated plumbing, water heaters, furnace, install central air, roof.

Maintenance guy has his electrical license and plumbing license.

For example, the house is old so if they see all new PVC plumbing in it and there was not even one permit pulled for that, you can be sure it's an issue.Here in Hollywood, Florida....I know a guy that purchased a home. 

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.
