Does Arch MI have a limit on acreage for a manually underwritten, portfolio and/or jumbo loan?

Our Standard Program guidelines indicate a maximum of 15 acres.  Arch MI will gladly consider an exception for higher acreage upon receipt of a full file for review.  Comparable properties should support good marketability with similar acreage, property styles and be common for the area.
