Managing an Airbnb and go to the basement of my multifamily to wash some towels. saw like 30 alcohol cans, pills, powerball tickets everywhere and one of my tenants mattresses on the ground.

So your "coming up with the cash" can't be mattress money, it needs to be legit seasoned funds. 

The “tenant” at some point moved a mattress, dresser, and some personal things into the front house and started renting out the back house on Airbnb.

All new mattresses,linens, appliances, etc so everything works and I don’t have to spend all day answering questions about repairs.

Does the bed have a $300 mattress on it or a $3,000 mattress?

Two properties can be exactly the same as far as an algorithm is concerned, but one is a true experience and the other is four walls with a roof and a lumpy mattress. 

That's the biggest downfall; folks think "zomg all cash, I can use $50k in cash that was sitting under my mattress, wahoo!"

Because once again, it's his opinion that his broken dvd, big screen tv, 8 year old bedroom suite with stained mattress and toaster oven have any value.

It was November and since the house was not rented, it will stay empty till March anyway.The lease was done under the corporations name so they could justify the corporate business expense.The house was empty with no furniture so it was a bunch of construction workers sleeping on the floor with air mattress.
