Keeping up with my financials is my least favorite thing to do. I know it is important but I still hate it. It is labor intensive. I use Quicken for all my financials both personal and business. At one time I did hire a bookkeeper through 1800Accountant but they did a poor job. I decided to just do it myself. I want to get in the habit of producing a monthly P&L. The next step is actually reviewing it. My habit right now is simply printing the report and filing it without actually reviewing it. The book has energized me to take my P&L more seriously.
I do separate my personal and business expenses. I have separate bank accounts for each.
I classify liquid assets as anything that can turn into cash quickly. Quickly meaning in less than a week.
I currently don't do a personal balance sheet but I will now.
The most important metric is whether or not I am making a profit.
My most important factors evaluating a property is the type of property, can it be a long term rental, purchase price, and the rehab. I prefer single family homes, purchase price below $150K, and not more than $20K of rehab. I have a hard pass on the purchase price.
