You are aware of the hazards of getting involved in S8 housing as a landlord, right?

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

One home is completely hands off and works like clockwork. 

At least starting off, that's the good approach. 

That said, the deal availability notably dropped off in 2020, and are virtually non-existent in 2021 thus far for buy/hold and BRRRR, even now in C class neighborhoods. 

Is it realistic to pay off the debt and still keep the house or better to sell?

Is there pavement haul-off needed? 

HI NatanYou can always start off on house hacking a multifamily in MI 1-4 units with min 5% down or 3.5% down for FHA.

. * We can only imagine the morass of bureaucracy it will take to administer Rent Control, housing will be forever taken off the market and it may encourage an illegal black market in Rent Controlled units.https://caanet.org/votervoice/You can contact your local reps here to fight this injustice!!

I read the Fannie seller guide and it says that a cash out refinance has a 12-month seasoning requirement if it is paying off an existing first mortgage: "If an existing first mortgage is being paid off through the transaction, it must be at least 12 months old at the time of refinance, as measured by the note date of the existing loan to the note date of the new loan."
