You will need electrical, plumbing, gas, and/or HVAC pulled by Masters in those trades, if applicable, depending on the scope of the project . 

Most NNN trades at no more than 10% off of the list price and many less than that or at asking price.

My interests have always been with the trades and my previous homes were a blast as they were both "long term" flips that provided me with some real-world experience...major jobs like adding bathrooms, bedrooms, converting spaces, kitchens, etc.

And to add a little more as you move forward in the process, for tax purposes, these transactions are not recognized as a sale of property, but rather as a trade of one investment in real property for another.

If you want to learn the trade of selling real estate and put on the realtor hat then I would recommend you join a team to start off to gain some experience as they will feed you leads and train you and likely will be a 50/50 commission split.

I'm a software engineer by trade, but work a lot with a property developer.

@Karen Casey, Trading deferred improvements for no cap ex is a good idea. 

Then it's a matter of getting in with some good brokers that know the market, the micro-markets as mentioned above and what comparable type properties are trading at.    

Do you have multiple Sub Contractors, for similar trade skills, such as plumbers, electricians, flooring crews, painters, etc.?

I have connections with different trades and was wondering if anyone has some tips on the pros and cons they've experienced with becoming their own manager on projects.
