A few things I do in my daily routine:
1. Browse the new MLS listings in my markets - I think it's beneficial to keep a pulse of what is out there, prices, and quality of finishes. It gives me a good idea when I'm ready to do rehabs with regards to market expectations and market supply.
2. Simulated Analysis - I'll take atleast one of the above properties and do a quick analysis on it as both a flip and a rental property. Even though I might not be interested in the property, I think it is healthy to go through the exercise of figuring out its property taxes, estimating what the property could rent for, estimate what the property could ARV for, and then to see what the cash-on-cash return would be if I wanted to pursue it. This keeps me sharp on numbers.
3. Visit BP - Atleast once a day, I will head to the BP forums and read some of the newest / most active posts. It's amazing to see the different angles people can approach RE Investing, and there is no better way to grow individually than to read / learn about others' experiences.
