Just my 2 cents - Your realtor is a "successful and high producer".. we have one of those in my area and I have witnessed this guy that has a fairly large team under price at least 2 properties.  

Who are the witnesses to the contract?  

I witnessed it first hand as I was already actively appraising during the housing meltdown.

Just follow whatever your locale's rules are for keeping the deposit.If you're concerned she might sue, it would be prudent to have a few other people do a 'sniff test' so you have a couple witnesses in small claims court that you're not making it up.But it's unlikely anyone would sue for $300 anyways...Unfortunately, that $300 likely won't he enough to cover your damages.  

I have witnessed it firsthand.

I understand that in some states, there needs to be a witness when the seller signs the contract.  

Even if we don't, there's always more opportunity for those who have enough wits and patience to find the right kind of opportunity.

You'll be scored specifically as an auto loan borrower, home loan borrower, etc.For what it's worth, my credit mentor is considered an expert witness by the court in credit-related litigation, and he chairs and sits on a number of committees which advise member of Congress on credit legislation.

We went under contract wit the first installment paid and about 2 weeks later he asked for an early partial second installment "to keep the project funded and moving smoothly" I was hesitant but i went ahead and did it. since then, he has left my roof open (improperly tarped)  while replacing it during the recent downpours we have had and we had quite a bit of water come in the house.

I got the time and persistence but want to witness it with my own eyes.
