I remember when I first started as an agent. Using software to manage the properties was my biggest fear, and I'd always avoid it. My boss told me I couldn't avoid this forever, so I started working on Buildium, which turned out pretty great. I work in Playa del Carmen Real Estate, and many houses are being sold or rented every day. It was impossible for me not to use the software. Check it out, it might work for you too. At first, it can be a little confusing, but you'll get the hang of it fast.
