Brent ButcherLeon mentioned Heritage at 19.5% - the big differences between Heritage and Mastro is Heritage lets you use credit cards to pay. I don't think Mastro offers this even with the increased premium. Also, Heritage will hold the cards for 6 months I believe while you pay them off(pre-qualified bidders only.)
I haven't taken advantage of either of these options but I'm sure that's a huge benefit to some.
With the increased buyer's premium Mastro could afford these same options and I would think the end result would help the sellers.
