You might look for a wholesaler that can find you a deal.  

I've told her I was a wholesaler but she should inform the seller as well.Thanks again.

Again a very good question, if you are currently doing a  wholesale deal per month and your buyers are happy you should grow as the word gets out to the investor community. 

Hope to see you fellow wholesalers and investors around and hopefully doing business with you in the near future.

Can't wait to hear from some wholesalers and note holders! 

I specialize in Wholesales, flipping Tax Deed Land Lots, Multiple Choice Offers and Seller Finance Rentals where both the Seller and the new Lease Option tenants pay me, leaving me with a little cash flow while I wait for the mortgage balance to go down and the property value to go up during the 1 to 3 yr Seller Finance period.

The question is, should I approach them as potential buyers if I have properties that I  buy at 70% off Retail?

As a Wholesaler, do I work with the Purchase and Sales Agreement and the Assignment of Contract or just one of the two?

Your options in your market are buy to flip, buy short term rental (Air B&B), wholesale, or buy for appreciation.
