I always have an updated real estate schedule on hand. I use it primarily when applying for a new loan or when networking with other investors if I'm looking for private money. It's a great place to have all of your property information handy and ready to send when needed.
It also paints a clear picture of where my properties sit; if I need to refi, raise rents, or if I have a chunk of equity sitting in one property that I could reinvest instead.
