DealWise reads the offering memorandum and the leases, builds the rent roll and underwrites the deal: NOI derived lease by lease, every month of the hold, levered returns, and an Excel cash flow model to download. What's different: it checks the seller's stated cap rate against what the rent roll actually supports, and tells you how far apart they are in basis points. Built for buyers, listing brokers and sponsors. Your first deal is free, no credit card.
