1. Unify the source data
Monthly investor reporting pulls from every data source in the firm: Yardi or MRI for property financials, AppFolio or Entrata for lease and tenant data, the fund accounting system for capital account balances, the asset management tracker for operational notes, and Excel spreadsheets for anything the systems don't cover. Step one is getting all of it into one governed warehouse with a daily refresh. Without that, every cycle starts with a data hunt.
