FAQ
Frequently asked questions
How do I know if a rental property is a good investment?+
Compare the income the property produces against what it costs to own. Start with our Rental Property ROI Calculator to work out annual cash flow after mortgage, taxes, insurance, maintenance, and vacancy, then check the return against alternatives. Cash flow, cap rate, and cash-on-cash return each answer a different question, so review them together rather than relying on one figure.
What is cap rate and how is it calculated?+
Capitalisation rate expresses a property annual return independent of financing. The formula is Cap Rate = Net Operating Income ÷ Property Value, where NOI is rental income minus operating expenses but before mortgage payments. Because it ignores financing, cap rate is mainly used to compare properties against each other in the same market. Our Commercial Cap Rate & Valuation Calculator works it out in both directions.
What is the BRRRR method?+
BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. The aim is to force appreciation through renovation, then refinance against the higher value to recover the original capital and reuse it on the next purchase. It depends on the after-repair value and the lender loan-to-value limit, so the refinance step is where the strategy usually succeeds or fails. Our BRRRR ROI Calculator models each stage.
