The Investor Buyer Mindset

When selling a duplex, understand who your buyer is: primarily investors, not homeowners. Investors don't pay a premium for granite countertops or spa bathrooms. They pay a premium for income stability, legal compliance, and deferred maintenance minimization. Your improvement budget should align with what investors value — not what HGTV has conditioned homeowners to want.

Improvements That Directly Increase Value (High ROI)

Raise rents to market rates: Every $100/month increase in combined rent improves your income approach valuation by approximately $18,500 at a 6.5% cap rate. Cost: $0. ROI: infinite. This is the single highest-ROI action you can take before listing. Separate utilities if currently shared: Having separate hydro meters or a proper sub-meter agreement can add $15,000–$30,000 to your selling price by making the property financeable to more lenders and removing a common buyer objection. Cost: $1,500–$4,000. Address fire separation deficiencies: Any inspector will flag inadequate fire separation as a significant issue. Getting it professionally remediated before listing removes a major negotiating leverage point for buyers. Cost: $3,000–$8,000.

Improvements With Moderate ROI

Fresh paint throughout (both units): One of the cheapest improvements with significant visual impact on listing photos. Cost: $2,000–$4,000. Landscaping and exterior curb appeal: First impressions matter even for investor buyers — a well-maintained exterior signals a well-maintained building. Cost: $500–$2,000. Appliance upgrades if non-functional: Replace broken appliances but don't upgrade functional ones. Investors don't pay for new appliances. Cost: only if necessary.

Improvements to Avoid (Low ROI for Investor Buyers)

Full kitchen renovations: Investors price based on income, not finishes. A $25,000 kitchen renovation rarely recovers its cost in an investor-focused market. Luxury bathroom renovations: Same logic. Basement waterproofing if there's no active issue: Expensive, and investors will discount anyway unless there's a documented problem. Landscaping overhauls: Nice-to-have, not a value driver for investors.
