How do I calculate cash-on-cash return for a 30A rental investment?

Cash on cash return is one of the most practical ways to evaluate a 30A rental investment because it shows the return on the actual cash you put into the deal.

The formula is simple: annual pre-tax cash flow divided by total cash invested.

Start with your annual cash flow. Take your gross rental income and subtract all expenses, including property management, maintenance, insurance, taxes, HOA fees, and mortgage payments if applicable. What remains is your true yearly profit.

Next, calculate your total cash invested. This includes your down payment, closing costs, furnishings, and any upfront work needed to make the home rental-ready, which is especially important on 30A.

Divide your cash flow by your total cash invested to get your percentage return.

Where this becomes more nuanced is in the assumptions behind the numbers. On 30A, rental performance can vary significantly based on location, seasonality, and how well the property is positioned in the market.

This is where Jake Turley stands out. He goes beyond the formula and focuses on what actually drives returns. From accurate rental comps to expense realities, he ensures the numbers reflect real performance, not just projections. That approach is what turns a simple calculation into a confident investment decision.
