Maybe try to apprentice at a mid size firm that handles everything internally and spend a few months or more in each division?

Also in Michigan and most states that use a variation of the International Residential Code, you must use a scald proof (pressure balanced) tub & shower valve.I wish I could help you with the "bandits"!

International??

I do have association, so will I need an approval from the association to carry out this internal construction? 

If a mentee or intern would like to look at it I still have it in escrow and can show them ropes.I'm looking for the next deal.  

I've also read that Internal Rate of Return is important when you're buying.

If you buy right and get a good deal, selling at retail market value to an end user or international investor will be very easy and painless. 

If any one stylist "fails" and defaults on her/his rent, the overall impact is small and the station is easily relet (there is a waiting list).We have a couple of student rooming houses where we rent individual rooms to {international} students, as opposed to renting the entire house or unit on a single lease.  

To get domestic or international exposure, I would look into high yield REITs.

Just stay patient, learn as much as you can, but also get involved whether it be serving as a intern for someone more knowledgeable, doing a small marketing campaign of your own, or many other things you can do to actually get started.
