I'm Charanpal Singh, a Kingston-based real estate sales representative working with buyers and sellers in Kingston and Cornwall. If you're looking at a Cornwall duplex, triplex or rental home, I'll help you screen listings, ask the right questions about the units and tenants, and run realistic numbers before you make an offer.
Cornwall sits on the St. Lawrence River along Highway 401, between Ottawa and Montreal. Whatever the purchase price, price alone doesn't decide your return. Rents, vacancy, repairs and financing costs do.
Right now, 224 homes are listed for sale in Cornwall with a median asking price of $424,900 (see the October 2026 report: Cornwall market report). These are asking prices, not sold prices, and cover all home types, not only investment properties.
There are no guaranteed returns. Here's a simple way to compare properties:
| Line | What goes in |
|---|---|
| A. Gross annual rent | All units, at realistic market or in-place rent |
| B. Vacancy & bad-debt allowance | Percentage you decide is prudent |
| C. Operating expenses | Property tax, insurance, utilities you pay, maintenance/repairs allowance, snow & lawn, property management (if used) |
| D. Net operating income (NOI) | A − B − C |
| E. Mortgage payments | Based on your actual financing quote |
| F. Annual cash flow | D − E |
| G. Cash-on-cash return | F ÷ cash you invested (down payment + closing costs + immediate repairs) |
| H. Cap rate | D ÷ purchase price |
I'll send you a free spreadsheet version when you request the investor shortlist. Figures you plug in are your own assumptions — check rents, expenses and financing with real quotes and your accountant.
Many investors live in Ottawa, Montréal or the GTA. I'm Kingston-based and work with buyers and sellers in Cornwall; we can review listings by video call, do virtual or in-person showings, and I can introduce you to local professionals such as home inspectors, real estate lawyers and mortgage professionals.
Investor consultations are available in English, ਪੰਜਾਬੀ, हिन्दी and اردو. Learn more.






It depends on the purchase price, rents, expenses, financing and condition of the building. No investment is guaranteed. Compare each property using actual rents and expenses, a vacancy allowance and a real mortgage quote, and have the building inspected before you buy.
A legal duplex is a property that is permitted by local zoning and building rules to have two separate units. Ask for documents such as municipal zoning confirmation, permits and inspections, and electrical and fire-code compliance where relevant, and confirm details with the City of Cornwall before you buy.
Yes, many buyers do. Financing and tax rules for owner-occupied multi-unit purchases can differ from pure rental purchases, so speak with a mortgage professional and an accountant before you make an offer.
Ontario sets a yearly rent increase guideline that applies to most residential units. Some units first occupied for residential purposes after November 15, 2018 are exempt from the guideline. Check ontario.ca for the current guideline and rules before setting or increasing rent.
Start with gross annual rent, subtract a vacancy allowance and operating expenses to get net operating income, then subtract your annual mortgage payments. Divide that cash flow by the cash you invested to estimate your cash-on-cash return. Use real quotes and your own assumptions.
Provincial rules have expanded where additional residential units are allowed, but zoning, servicing and building-code requirements still apply and vary by property. Confirm what is permitted with the City of Cornwall before you buy or build.
Ask for current leases, the rent roll, proof of rent payments, utility bills, property tax and insurance details, and any maintenance or repair records. A real estate lawyer can advise on tenancy-related conditions in your offer.
