Transparency.

Everyone on either side of the fence wants to fund solid volume as quickly and efficiently as possible; the key is having folks who understand the product scope, submit within the eligible parameters, and have it taken from A - Z without hiccups and the constant back-and-forth. When both ends are well versed and have a fluidity in deal flow.. everybody wins. This also includes being extremely forthright in all aspects from details on submissions that may prove problematic to flexibility (or lack thereof) on approvals... commission, expectations etc.
