I would under-react about the house cleaning as they will be quick to retort that they are in the process of moving - just state that it would be helpful to have the apartment "show well" so you can get this part of the process over with and both you and they can return to preparing for the transition.

You will not retire or grow rich off cash flow, it will be the appreciation and eventually the loan payoff. 

This negative position can consume years of cash flow to recover.

Why 50% DSCR with very little cash flow?

However, the cash flow seems to make sense and I am wondering if this could be a good opportunity. 

I’m working with my father on managing his RE portfolio.We have one multi family property that is fully paid off and generates roughly $200k in NOI/Cash Flow.

I’ve bought 10 buy n hold SFR in the last year that cash flow.

I am not sure why is that but you have to be careful on what are the agreement on that contract.In this case, I would recommend to get involved with a investor friendly realtor who will help you as it could be many issues during the process as the titles are not clean in most cases and many variables have to be checked. 

@Shawn Carrico-Phillipsit's tough to answer this because it will depend on your own goals, values and preferences.but as you may have noticed, it is very, very difficult to cash flow right now on long term rentals with conventional debt. 

There are a TON of tiny/small towns in MN where $70k will buy you a house outright that will definitely cash flow.
