By end we re-did the entire mechanical system, EVERYTHING, had brought in structural engineers for the complete rebuild of the 2nd story, our $35k reno went too almost $80k, it was THE nightmare flip.

I've always loved and learned about houses, from mechanicals to design, and I'm ready to work. 

Servicing the mechanical units goes a longgg way.. 

I am however handy, I have a degree in biology and I do have a trade skill set in automotive mechanics, and I am always willing to return the favor for anyone pointing me in the right direction.

. - i like to think I’m pretty handy, I’m am a retired mechanical engineer.

If you are not touching mechanicals then there won't be an inspection until you go to sell or refi to put a renter in there. 

The basement also houses all of the mechanicals usually, so you would be sleeping with the furnace and hot water heater.

You will want the full set of plans: elevations, electrical, mechanical, plumbing, floor plan with signatures and seals.For the mini split, some recommendations: If you're going to use 2 heads (one for living room, one for bedroom), get 2 separate single zone outdoor units (not a multi-zone).

Just trying to think through the mechanics of how this will actually play out.  

There are definatly some bad contractors out there , jut like any other business , car dealers , flippers who cut corners , mechanics , etc .
