Rental Income
A modular home that pays you back.
Free calculator for any Modular Home — cash flow, cap rate, 10-year ROI. Works whether you're adding an ADU, buying a unit to rent out, or putting cabins on cottage land. About two minutes.
Built for Canadian tax rules
Interest deductibility, vacancy, and CCA implications are factored into the after-tax cash flow math — not a US-flavoured calculator.

Ontario Bill 23 baked in
The development-charge waiver for most ADUs (a $20K–$50K savings) is automatically reflected in your project cost.
Financing side-by-side
Cash, HELOC, mortgage extension, or standalone unit financing — compare each against your actual numbers and rate assumptions.
Results are illustrative and based on user inputs plus typical assumptions. Modular Homes 400 is not a tax advisor, lender, or financial planner. Consult a qualified professional before making investment decisions.
FAQ
Quick answers before you run the numbers.
Is there a free calculator for modular home rental income in Ontario?
Yes. This is the only Ontario-built rental ROI calculator that combines CMHC market rent by city, the Ontario Bill 23 development-charge waiver for ADUs, and Canadian tax rules (interest deductibility, vacancy) into a single cash-flow and ROI model. Free, no login required.
How does Ontario’s Bill 23 affect modular ADU rental ROI?
Bill 23 (O. Reg. 299/19 amendment) waives municipal development charges on most additional residential units in Ontario. That removes $20,000–$50,000 from the project cost. The calculator applies the waiver automatically when your scenario qualifies, lifting cash-on-cash return and shortening payback.
Can I deduct mortgage interest on a modular rental property in Canada?
Yes. CRA allows full deduction of mortgage interest used to earn rental income, alongside property tax, insurance, repairs, and other operating costs. The calculator includes interest deductibility in the after-tax cash flow. CCA on the building is optional and shown separately.
Where does the rent data come from?
CMHC Rental Market Survey — Canada’s national rent benchmark, updated annually for 30+ Ontario metropolitan areas by unit size. The calculator uses CMHC as your starting estimate, but every input is editable so you can override with a local rent read.
Does the calculator work for a cottage rental or a single-unit ADU?
Yes. Three use cases are built in: adding an ADU to your property, buying a single modular unit to rent out, or putting multiple cabins on cottage acreage. Each path applies different financing, occupancy, and Bill 23 assumptions to your scenario.
