Tangibly, this could be a detached or attached space converted, or maybe you find a master down floorplan with other bedrooms upstairs (and that master has a door to the outside and is large enough to add a kitchenette tapping into water and drain from bathroom or kitchen).

For the past two years I have been meeting with an Investment Real Estate Master Mind group.

Is there a master policy with the association that covers the structure? 

Apparently this Master Plumber on record for the co had used the cos ins info and name to pull permits for my job but he didnt really do the job thru the co he worked for.

Tenant can program their own code while you retain the master and the key for emergencies.

Went to Seguin HS & UTA for my masters and undergrad My wife & I house hacked our way to our first rental property here in Fort Worth. 

If you are just getting started, you don't have the scale of the bigger groups who may be on a master policy and have a premium much lower than what you'd qualify for. 

You could also create an individual spreadsheet for all 15 properties and have them all flow into a combined master sheet.

example: i was looking at a multifamily portfolio that was master-leased by a college. that master lease made the portfolio worth, on paper, 10x what each property would've been worth otherwise. it would've been crazy to pay the higher price, because if that master lease ends, i'd be totally screwed. 

This would be new kitchen, new master bath, full painting interior and carpeting.
