We've been working on bylaws, registered as a non-profit, set up a bank account, drafted application forms, discussed membership fees, and a whole bunch of other stuff.

Nothing against them, I’ve gotten some decent properties from them, but as a buyer I’m looking for more of the Lone Ranger wholesalers because there’s more flexibility on the price and not additional fees on top.

Option fee goes to attorney's fees. 

and remove my name from this property since the owners have paid me the redemption fee I asked for.

Inspections, title, and closing fees could be $2,500+. 

The only reference I have is for my duplex and triplex properties in CO; sewage, water, garbage and share common area fees paid by me; tenant pays gas and electric.

don't ever discuss reas their application fee rather than falling for the threat

The annual filing fee is $50.

Oftentimes in Sheriff's sales the final judgement amount is published whereby you can see how much the bank is owed, including outstanding balance, interest, late fees, legal costs, corporate advances for insurance, taxes, etc. 

Are the fees negotiable?
