I would use a company versed in this process to manage the operations of the LLC and collect the rents/operating costs for the owners. 

I cash out refinanced my primary in 2019 right at the start of lockdowns with the idea of buying a new home and rent my current.

That way you can acquire, renovate, and either sell off or rent. the fix & flip is a 90% ltv + 100% renovation. ex. pp: $72k Loan 90%ltv: $64,800 + $11k reno= $75,800- that’s the minimum loan amount met and we can close.

If you have $100k to invest and put as a down payment, would you get 1-2 places that have a Cash on Cash (COC) of $500+ a month but no appreciation, or 1 place with a 5-8% appreciation each year but you break even or lose $200-300 per month on the mortgage by renting out? 

I just purchased a duplex about 3 months ago and recently had the lower tenant move out because I raised rent higher than she could afford. 

-Rents will be steady for the foreseeable future , no rent increase factored in-interest rates are steady state (unlikely, downward bias is likely)Y1 Build one triplex - one detached with apartment and one detached garage with a apartment above.

The housing price is so high compare to the rent. 

Who do you foresee will rent this for a few months?

I would unload it or if investing refi and rent it 

I don’t like the area to live in but i could rent it out .
