In re Scottsdale Medical Pavilion. 52 F.3d 244 (9th Cir.1995), aff’d. 159 B.R. 295 (9th Cir. B.A.P. 1993)
    (Az. law) because creditor properly perfected security interest in rents, prepetition rents constituted cash collateral

In re Days California Riverside Ltd. Partnership, 27 F.3d 374 (9th Cir.1994)
    Postpetition hotel revenues, encumbered by a prepetition trust deed and security interest are ‘proceeds, product, offspring, rents or profits’ under §552(b).  A major premise of hotel financing is the stream of revenues.  Hotel room charges are held to be ‘rents’ for security purposes and thus subject to the lender’s prepetition lien.  However, the net revenues, after allocation of expenses, derived form food and beverage service are not ‘rents.’  See also In re San Francisco Drake Hotel Assocs., 131 B.R. 156 (Bankr. N.D. Cal. 1991), aff’d, 147 B.R. 538 (N.D. Cal. 1992).
