Otherwise aren't you at risk of a  potential cascade affect of mortgage foreclosures if several tenants cannot pay their rent.What is the recommended BRRRR strategy to full-proof your investments, regardless of the economy?

What other factors/items can I check to reduce risk in such a case ?

But I'll leave you with this -- somebody else's crappy risk management practices do not need to dictate yours. 

I am reading and am wondering if I can draw up all the numbers and possible risks, would someone be willing to engage in a partnership with me?

I have enough money for the down payment but I need help carrying the loan.

It would take probably $50k-80k to get the home to a condition that it may sell in the high $300's - maybe - not at all worth that high of risk in my opinion. 

There are usually a lot of attorneys and title companies involved in wholesaling....I don't think all those professionals would risk their credentials if what they were participating in was illegal.Like everyone said, look up your local laws as they are different in all 50 states but as long as you are following the language in the contract the seller has signed you should be fine.If it says don't market, don't market, if it says no assignment, don't assign...if that's the case, get a new contract.

I’ve considered the risks in this route.

In your case, I think $200 is reasonable because they obviously care for the property  as if it were their own and you could avoid a costly vacancy or the risk of a lesser tenant. 

How big of a risk am I taking?
