Questions about Property Investment ROI Calculator
Clear answers first. If one question changes the deal, bring it into the review before you move money.
Q1Why is cash flow a misleading measure of return?+
Because it's one of four components. Total return also includes appreciation, principal paydown by tenants, and — for a high earner — the tax benefit, which is often the largest line. Judging on cash flow alone undersells the asset here.
Q2How do I calculate total ROI?+
Add annual cash flow, appreciation, principal paydown, and estimated tax savings, then divide by total cash invested. That total-return view is why a deal with thin cash flow can still pencil for a high-W2 buyer.
Q3Why is the tax-savings line often the biggest?+
Because depreciation (accelerated via cost seg and bonus) shelters income, and in the STR case can offset W-2 income at a high marginal rate. For an $800K+ household, deductions are worth more than to an average earner — that's the leverage.
Q4How reliable is the tax-savings estimate?+
Treat it as an estimate until your CPA confirms it. The offset depends on structure, participation, and your specific return — the calculator shows the shape of the deal, but the CPA sets the real number.
Q5Can a deal with modest cash flow still be worth it?+
Yes, if the tax savings and equity build carry it. Many high-W2 deals here are justified by after-tax total return, not monthly cash flow — provided the CPA confirms the offset applies.
Q6How do I model this against my real tax rate?+
Plug in your actual marginal rate and a specific property's structure, CPA in the loop. That total-ROI-including-tax modeling is a core part of a Real Estate Review.
