George - there's been some controversy with regards to the LP/SP ratio. You're calculations generate the reverse of what's asked in the form: SP/LP ratio (ie: .92, or 92%.) The form as initially released asks for the LP/SP ratio (1.10 in your example.) The controversy centers on FNMA's decision to opt for the LP/SP ratio rather than the industry-accepted SP/LP (as used in ERC forms and MLS's nationwide.) I've heard FNMA plans to revise the form to the widely-used SP/LP ratio. So, while your calculations make sense, they are actually opposite of what the form is asking. Charles Baker, SRA
