How do I choose/find a buyers agent?

Just thought it was odd and buyer beware and all that.

The problem is we thought we had a credible buyer for this property (BKA 5D Financials).

You have the option of entering into a lease purchase with your friend that makes you the tenant/buyer and her the landlord/seller or making a purchase of the home subject to the existing mortgage.A lease purchase gives you the rights and responsibilities of the owner without title.

That being said, if you want to wholesale I would focus on three things:Learn to evaluate deals-Find out the ARV-Estimate Repairs-Think of best possible use of property (SFR to duplex, or commercial etc. etc.)Find buyers for your deals-Auctions-Craigslist-REIA meetingsFind deals and put them under contract!
