Is there a book I can read or a podcast I can listen to that breaks down the steps for a rehab - starting with how to pick a contractor, how to prepare a SOW, what are the steps in the rehab (ie first you fix the roof, foundation , windows and exterior doors and then plumbing, etc.) , what work can be done at the same time (ie plumbing and electrical) etc.   

., roof repair, window replacement, floor replacement, painting, etc.

A short time after a hurricane blew some shingles off the roof and caused a leak.

Why are you buying where the neighboring buildings don’t have roofs?

If you're good with these numbers, get a house inspection to find out if there are any other problems with the roof, foundation, HVAC, etc.Lastly, keep in mind that a big job like renovation is much more difficult if you're living in the house while work is being done - doubly so if you're doing the work yourself while living there.All the best with it!

Too many licensed and Ivy League educated financial managers funneled so much cash into RE market since COVID that property values skyrocketed and as a result  tax assessments of properties went through the roof.

I believe they stopped using knob and tube wiring sometime in the 40s.Roof - Of course in that amount of years, most likely the roof has been replaced at least a couple times, but this is also a big ticket items to look closely at.Plumbing - I think it was sometime in the 80s when PVC pipes were starting to be widely used.  

However your returns are probably even lower if you factor in upcoming major expenses like an hvac or roof replacement.It really depends on your goals. 

Some investors want a truly hands-off approach, and in that case the more units under one roof, the better.

This can tell me a lot about the age of the plumbing, roof, HVAC, etc before actually walking it.
