Investsum Rental Property Manager (RPM) is an interactive property management software application for the individual investor. RPM is designed to efficiently and easily receive, store, and display data on real estate owned and managed by the individual investor. RPM stores data on properties, tenants, loans, insurance, income, expense, vendors, etc. and can generate reports ranging from income and expense to mortgage loan reports. RPM is user-friendly and uses meaningful data fields. RPM revolutionizes the way investors organize and manage their properties. Additionally, unlike other rental property applications RPM does not limit the user to a certain number of properties they are allowed to enter into RPM.
