If you open up the wall to do something, you will need a permit for plumbing and electrical a lot of the time because they will want to see behind the wall before you close it.

I think flipping is the way to go on this project since it’s my first deal which has always been the plan but very grateful for some guidance. 5 weeks of tear out, wall paper removal 🙃, new electrical, deck supports, HVAC install…we start putting it back together!

I hope they are an even better experience beyond the credential wall.

These have two very different next steps.If it is a condo, you need to check your condo docs and see where the unit ends and what is common area. if its a leak in a pipe in a wall that is typically common owner and the condo association should take care of it.

Flood vents need to be installed in those block walls.

Forming little groups in the background to down vote certain individuals comments based on skin color, or religion, or perceived political leanings seems like something we could all do without on this forum.

Otherwise you may be put into a situation where you have your back is against a wall and you have no way out.

I'm sure in markets that differ from mine that people will have very different experiences.I'm in a VERY blue color cash-flowing market.

I expect it to be moderate size rehab which to me means no significant plumbing or electrical and no walls being added or removed.  

Know that the market you're serving does exist, and is like an underlying current that's being held back by walled garden that the government has only recently scrutinize.Zillow, Redfin and Trulia has all attempted at disintermediation and increase market efficiency, but failed due to the market powers that maybe.
