About Us

PBS LLC was organized as a credit union servicing organization [CUSO] in 2006 for the purpose of providing commercial real estate lending services to our credit union [CU] members.  PBS provides loan origination and origination support to our members, as well as underwriting, loan servicing, special servicing workouts, participation administration, commercial policy and procedures, regulatory support, consulting and advisory services.  Our ability to participate loans amongst a wide array of CUs provides borrowers and lenders with flexible and scalable lending and borrowing capacity.  In addition, by centralizing participation administration, PBS can trade participation shares amongst its members at low or no cost.  Because of our broad membership base this trading capacity during any time in a mortgage’s life cycle provides our members with unparalleled loan liquidity and risk mitigation tools generally unavailable to non-members.

PBS provides mortgage lending products primarily within the middle market segment of the commercial real estate economy with loans from $2 million to $20 million.  We specialize in financing of the following property types:

  • multi-unit residential properties
  • triple net lease properties
  • national credit anchored retail properties
  • non-anchored multi-tenant strip retail centers
  • mixed use properties
  • owner occupied office/retail/light industrial properties
  • GSA government leases
  • Real Estate secured working capital lines and loans
  • brokered owner/occupant
  • warehouse/flex properties
  • construction, tenant improvement, and renovation
  • hotels


Owned by five local Credit Unions:

  • Andrews Federal Credit Union
  • Apple Federal Credit Union
  • Lafayette Federal Credit Union
  • NASA Federal Credit Union
