That is where you make the move to evict or warn then evict.

I usually don't chase bad money with good and agree that your $20k against a 6 figure monthly bleed won't move the needle.

I understand that I should have a separate bank account from my personal checking/savings, but based on my research, this first deal won't necessarily provide cashflow with me living in one of the units (it will when I move out).

Currently, have a property that has been on the market for some time, spoke with the agent and the sellers are trying to move forth due to another property.

Where would you live if you moved there? 

So I have no reservations about moving and renting it out. 

My understanding is that assuming that one has no debt other than the mortgage for the first househack, it is calculated as(PITI1 + PITI2) / (Monthly Paycheck + 0.75*Rent1 + 0.75*Rent2)Rent1 is the total rent collected from the first property assuming that you have moved out and have fully rented it, and Rent2 is the rent collected from the other units in the new multi-family property that you want to buy.Is this correct?

During restretching, we may need to move some of the tenant’s furniture, though we will work around it if we can.

But there is still a lot more risk baked in - a lot more moving pieces, a third party is involved, a lot more chances for things to go wrong compared to #3. 

Paint was a year old in great shape when she moved in and she was here less than a year.
