I have a home owner whose house I made an offer on and he wants an earnest deposit which is fine. He wants me to meet him and do it thru the title company but my intention is to Wholesale it. Do I just get the purchase and sale agreement signed there at that time then move forward with finding a buyer? Will everything be alright with a buyer? 

before you go looking for deals, you should already have a buyers list. Worst case scenario you lose your earnest money and create a bad rep for yourself. If it's a sure deal as in 70%-repairs and minus your wholesale fee is the sales price. you shouldn't have a problem. Sign it and take it to title with at least two weeks till closing. If it doesn't meet that criteria. My 2 cents you setting yourself up for failure and screwing the seller because you have no intentions on closing the deal or know anyone who is going to.
