The 50% rule states that approximately 50% of EGI will typically be consumed by operating expenses.While the 50% rule provides a quick estimate, actual expenses can vary widely depending on the property type, location, age, condition, tenant mix, and market conditions.Here's an example: if a property generates $200,000 in EGI per year, the 50% rule suggests $100,000 would go towards operating expenses like taxes, insurance, utilities, and property management.

The question regardless of what market you're in is: "How do I add value?"

I didn't pursue because the real estate market was good and rates were at an all time low.
