Great question. The best practice is to have multiple “underwriting scenarios”, worst, good, and best case scenarios to start. Example: Worst case - may include stagnant rent increases, vacancy rates 5-10% more than the market average, and a surprise $10k capital expense (maybe HVAC replacements) Good case - 5% annual rent increases along with expenses increasing 3% Best case - 15% rent increases and vacancy rates are 2-3% less than the market average The more scenarios you run, the more clarity and visibility you will have. This can be achieved with the software by tweaking these items and saving off each scenario.
