I did one with Central Mtg a long time ago. It was finally successful, but we lost the first buyer during the process. Overall they were responsive and quick. The problem I ran into was the investor. Hopefully they've gotten better. Good luck.
I closed one with with Central few months ago. The drama was caused by the buyer and her agents. 1st buyer walked, closed with the 2nd buyer. Chase had the 2nd lien, and I don't need to tell you that was not easy.
