Building Real Estate Cash Flow

Net operating income is your gross rental income minus operating expenses such as property taxes, insurance, repairs, and management fees, calculated before any debt service. Cash flow takes NOI one step further by subtracting your actual mortgage payment, both principal and interest, leaving the amount that actually reaches your bank account. Two properties with identical NOI can produce very different cash flow depending on how much debt each carries and at what interest rate.

Cap rate equals NOI divided by purchase price, expressed as a percentage, and is used to compare the income-generating potential of different properties independent of how they are financed. A lower cap rate generally reflects a property perceived as lower risk or higher quality, such as a well-located, well-leased asset in a strong Puget Sound submarket, while a higher cap rate often reflects higher perceived risk or a less desirable location, though cap rate alone does not capture every risk factor.

Lenders use debt service coverage ratio, calculated as NOI divided by annual debt service, to determine how much cushion exists between a property's income and its loan payment obligations. Most commercial lenders require a minimum ratio, often around 1.20 to 1.25, meaning the property must generate at least 20 to 25 percent more income than the loan payment requires. A replacement property with thin coverage can limit your financing options or require a larger down payment.

It depends entirely on the specific properties involved rather than the property type in the abstract. An investor moving from a management-intensive residential rental into a triple net leased property might see more predictable, though not necessarily higher, cash flow due to lower operating expense volatility. Someone moving from a stabilized asset into a value-add property might see lower initial cash flow with the goal of higher income after repositioning. We model your specific scenario rather than relying on general assumptions.

To fully defer your gain, you generally need to replace any debt paid off on your relinquished property with equal or greater debt on the replacement property, or offset the reduction with additional cash. New financing at current interest rates can result in a different debt service payment than your prior loan, even at a similar loan amount, which directly affects your post-exchange cash flow and is a factor we model explicitly when comparing replacement property options.
