Sale-Leaseback Case Study

Hi, I am in the process of interviewing for a RE Analyst position at a small PE firm. They give me a case study to complete. It has three tasks to complete:

1) Fix a broken model (I can do this by tracing where the source of the error)-no problem here. 2) Create a sale-leaseback toggle into the cap structure that flows through sources-uses, and projected balance sheet and income statement. Additional data are provided (sales-leaseback size, cap rate and percentage rent escalation). My question is can someone tell me what does this mean? I am not sure exactly what to do but my instinct tells me that the instruction means to replace the source of the funding from debt to sales-leaseback. Is this the correct way to think about it? 3)Model returns to equity investors and management using given assumptions (I think I can do this no problem)
