Companies: 1 %.Estimate for guidance only, not tax or legal advice. Rules as of September 2026.

    Net rental yieldWhat's left after the recurring costs of actually letting this unit out, on top of the rental estimate above.Vacancy assumes 30 days between tenants (default of 1 month — not enough history for this building yet).Estimate for guidance only: based on asking rents (not signed contracts) and simplified tax/fee rules.
