FWIW Its California , you probably need a permit  to do just about anything as long as you pay the fee 

Hey BP family, I'm currently trying to help out a family in need from having to foreclose on there property by taking over subject to, it has a high interest rate although the entry is around 20k I want to wholesale this ultimately Is it possible for me, to disregard my initial assignment fee to get a buyer asap and add a 2nd lien on the property as my fee? 

After all, you have no evidence they agreed to pay rent or any of the other terms.

I don't see them showing up or paying any of the back rent that's due to become current if they wanted to stay.

I was wondering if it is worth paying for BP pro membership for the special discount with Home Depot (e.g. flooring, appliances, etc). 

You can learn from someone one step ahead of you and then do business together.I'm sure there are plenty of mentors you could pay substantial money to to gain knowledge and know how but i doubt it could replace actual relationships that are pertinent to your market and current business.

They put one of their employees into one of my houses, and after I switched to a new property manager, that tenant stopped paying rent (amazing!)  

Nor would paying people to moderate.

The prices in the markets we looked at i.e. troy, Schenectady and Albany all had great prices and rents were inline but kept coming back to "what if the tenant doesn't pay". 

If you own this as a rental then there is not homestead exemption and you'll pay much higher tax rate than a resident/owner occupant in SC.
