You need to turn over some of that control to an experienced GC who can manage the flip for you.

Are they under rent control?

After months of here pressuring me to go DoD as GS once I retire (Which is the last thing I want, my life and time being managed without control) But, she’s opened up and talked about doing "flips" as a direction and is excited in that aspect.

You need a good source for local landlord tenant laws, a  reserve account for the unexpected, setup a payment tracking system, find a handyman, set expectations with your tenant about what constitutes a valid emergency, have the tenants sign a "walk through" list with photos of the condition of the house, make sure they have renter's insurance, 

Every market, submarket, property type and platform could potentially have it's own systems that work best for it.

In my experience i’ve seen higher returns with some of the small properties because they are owned by mom and pop and have a lot of room for new systems and processes. 

The exterior is terrible and needs to be redone, the inside looks bad too with the ceiling and walls falling apart, and I'm guessing the hvac and other systems will need to be replaced.My question is, can somebody give me a ballpark estimate of how much it would cost to rehab this house?

You may also want to tell them other products that will damage the septic system as they are different then city sewer systems.

Can we discuss the pros/cons of getting a cash flow property that has a renter in it already vs. getting a new renter in areas that are not rent-controlled?

The system told me to take the 24K deduction while me loss is about 50K.
