When I use to wholesale I would get many properties under contract for $10 dollars earnest money deposit. But I also, would get many sellers who had a problem with this as well.
Calus, put yourself in the seller's shoes. If you were selling a property you owned would you be comfortable with seeing an earnest money deposit for $1.00 dollar or one for $1,000 dollars?
1. In order to make the contract binding there has to be consideration and the earnest money deposit is consideration. So what ever source told you, you do not need to have an earnest money deposit, I would, even if the seller is willing to accept and sign the contract without an earnest money deposit, I would still have an earnest money deposit for the reason I just mentioned.
Also the earnest money deposit not only protects the seller, but it also protects the buyer (Wholesaler in this case); because without the earnest money deposit, the seller can technically pull out of the deal because there was never an earnest money deposit, therefore there was no consideration to make it a legal agreement.
2. Here is what I believe will avoid you having an issue with the vast majority of sellers regarding the earnest money deposit amount regardless of the amount $1.00 or $1,000 dollars. Find Motivated Sellers !
Many Motivated sellers really don't care about the earnest money deposit, they just want to sell this property not because they want to or need to, but because they HAVE TO. The key to overcoming the earnest money deposit is to find motivated sellers who HAVE TO sell, and that is not easy.
I hope this helps.
