My only experience is in building a brand new home with a new foundation.I am having a hard time understanding the order of events on an add-a-lvl as it seems more complicated than a new build.When should I demo and am I just bringing the entire interior to the studs?

If the tenants decided they needed to move in sometime during the summer then the only hinderance from a "livability" standpoint is the one bathroom that has been demoed for roughly the past 2-3 weeks (finished today) but there is another bathroom available (not sure if this has any bearing but wanted to mention). 

@Johan Yang I would do some searching on this topic.

Two 15-yard dumpsters later and we had the bathroom demoed and most of the main level and basement cleaned out.

I am thinking about just demo-ing the attic so it won't have circulation issue.

Once done it should be worth at least $120k but im hoping for $140kmy first price quotes for the demo were $13k, $11k, $9800, and $4200 ( a contractor i used prior)the demo is done now ( took 3 days down to joints)My quotes for remodel were $110k, $80k ( i would still have to provided appliances, granite, cabinets, all bathroom supplies), $35k labor only( i buy all materials)I'm going to go with the $35k labor and contractor said materials should be more than $20k so total including demo should be 60k, but gonna have a 10k fluff space.purchase plus closing fees: $9800Renovations plus demo: estimated $60k-plumbing-electrical-hvac-drywall and stods-roof repairso im looking around 70k plus inspection fees ( plan on refi after 6 months to cashout)wondering how much i could rent for in the area?????

I traded rent to get all the demo done for the plumbing and all the old cabinets torn out.

Why not buy up a strip of those old crap 4plexes, demo them and put in condos or such?

@Wei Jie Yang, that depends on a lot of factors.
