There are no interior pictures on the listing - none and no viewings.Price of property is pretty interesting though. ( I am not a fan of gambling )How i can see inside of property ?

Interior cameras are illegal.

I was told the red tag was placed due to no permits but I myself have seen the permit for this place on the interior wooden framing prior to the Sheetrock going up for the walls inside.

I think it's a hard question for others to answer for you, because it's entirely dependent on the nature of the project and your own interests and aptitude.I was my own GC (while working a full-time W2 job) on a 6-month remodel of a big house where we reconfigured the interior space, including relocating a staircase, converting part of the garage into an additional bed + bath and replacing the kitchen. 

There are suppliers in China who can supply pre-cut SIPs and they say they can source other exterior and interior finishes (except electricals and plumbing) from other suppliers and ship it.

Check everything like handrail on the interior stairs to make sure none of the brackets are broken, loose electrical sockets etc.It will depend on the age and condition of the house.

I wouldn't rely on AirBNB - at all.The HOA is highly unlikely to rebuild the interior of your condo...have you checked on that?

We actually found a great painter that also did amazing drywall work.So when we rehab he prefers us to leave the taping to him but its not more than a couple of rooms.Last one was $750 to paint the interior of the house plus a couple of rooms of drywall as we flipped the closets etc.

The house will need new interior everything - plumbing, electrical, kitchen, bathroom, walls, etc. 

The contractor I hired to paint interior of home has left it incomplete.
