In need of major repairs and is not suitable for living due to some fixing that are safety issues but has potential?

My rehab model is usually 15 days for a cosmetic only with curb appeal, 30 days if you need flooring, trim, kitchen and bath updating etc, 45 if you add kitchen or bath gut and rebuild and 60 if you need extensive work or special order items like siding etc. 75 or 90 if you need longer.I sell my rehab clients on getting their house ready to stage a day before the 15th, 30th, 45th or 60th.

@Jim GoebelThank you very much for sharing your perspective, your thoughts are very useful for me, I have a little break from managing everyday issues, so I was thinking to make some decisions on who is responsible for  working fire detectors, what company to hire to check detectors and other safety issues, I am going to sign an addendum/reminder that people would not use basements as a bedroom if there are no 2 exits. 

I'm not going to name specific markets but there are a LOT of cities throughout the US within geographic boundaries that are often very close to each other, that have extreme disparities in income, educational attainment, safety, etc. 

We couldn’t have holes in walls or floors, had to have running water, and a few other “safety and security” issues that I can’t recall right now.  

Unless there is a safety issue, I wouldn't touch the bathroom until the unit is vacant.

Goal for Q2 2019Because our model is broken down like an assembly line, and each position is highly leveraged on other positions, we discovered we need to make a leap of faith and triple the size of our organization.

It would be the landlords responsibility however since it is the ceiling unless their is a safety issue he would not be required to repair it.

But part of this game is following the Pareto Principle and building in a margin of safety for the big-ticket items. 

The immediate cash flow is more like a safety cushion at this point rather than money I have to have to spend now.
