You give them the down payment (20-25% down) and they hold the note for the rest of the money. 

Would he be willing to take some cash up front and the rest at closing if you were to flip the house?

I tried talking to the tenats upstairs already and they’re saying that the girl is only there from 4 pm and rest of day and night since she goes to school in morning.

@Emmanuel Ayobamibo Afuwape it doesn't make much financial sense to have $6k-$12k sitting in a bank paying maybe 2% when the balance on your credit card is costing you 15%-20%+  Keep enough for your emergency fund and put the rest towards the CC debt that is a guaranteed return.

You should then be able to use that to see how your county has classified them, and then use that knowledge to find the rest. 

After doing some hefty learning for the past several months I am failing to understand the described below scenario: If I buy a multifamily property at 600k with 20% down and finance the rest at say 6%..after running numbers my cap rate comes out to about 8% and cash on cash return at about 43% (its 12 units at approx 575 monthly rent income, and the report shows 30k a year in expenses and 80k in gross.

Once i find what is working, I will turn the rest off.

Thank you for sharing your honest assessment of what is going on and how you are attempting to work it out including seeking help on this forum.It helps out the rest of us know that we can do it too despite the challenges we know could and will happen.This reply is more encouragement and kudos to you rather than advice.

To completely renovate the rest of the house it would run about $55/sf in my area, which equates to 1050sf x $55/sf = $57,750.

Get them to either assign their lease or sublet to someone else with your approval or tell them they are on the hook for the rest of the year rent.
