Frequently asked questions
Rental yield measures what a property generates when let out, relative to its purchase price. There is a distinction between gross yield and net yield, the latter being more realistic.
- How do you calculate rental yield?
- Gross yield = (monthly rent × 12) ÷ purchase price × 100. Net yield first deducts costs, tax and rental vacancy from the annual rent, before dividing by the price.
- What is a good rental yield in Dakar?
- It depends on the neighbourhood and the type of property. Jamm's tool calculates your gross and net yield from your real figures, with no made-up estimate, so you can compare several properties objectively.
- Should rental vacancy be factored in?
- Yes: a few weeks without a tenant each year lowers your real income. The tool lets you enter the vacancy to get a realistic net yield, rather than a theoretical one.
