When managing rental properties, it is important to utilize the most efficient and most reputable property management software/technology.
When you are self managing, and running your rentals more so as a hobby versus a business, you can easily get by with Excel. You can track all of your expenses and income by manually inputting every entry. In my experience, this will work OK for a little while. However, once you get those months of multiple line items of expenses and lose track of things, it can become detrimental quickly.
At Cincinnati Real Estate Group Property Management, we utilize the property management software known as Buildium.
