Room Rental Calculator

Renting rooms individually produces 20–40% more income than whole-house rental — at the cost of higher management overhead. This calculator prices rooms with premiums for size, amenities, and furnishing.

How the math works

Room-by-room renting typically produces 20–40% more income than whole-house renting. The premium compensates for higher management overhead (multiple tenants, coordination), higher wear, and higher vacancy risk on a single room turnover.

Furnished rooms command another 20–30%. Furnished rooms with utilities included are popular with traveling professionals and medical residents — typical 3–9 month stays produce better cash flow than month-to-month unfurnished.

Frequently Asked Questions

Is room rental legal everywhere?

Most jurisdictions allow it but with occupancy limits (e.g., 1 person per bedroom plus 2 additional). Some college towns and HOAs restrict unrelated adults per household. Check local zoning and HOA rules.

How do I handle utilities with multiple tenants?

Either include utilities in rent (simpler) or split them via RUBS (Ratio Utility Billing System). Including creates predictable rent at a premium. RUBS rewards conservation but requires admin.

What lease structure works?

Either one master lease with tenants listed, or individual room leases with common area shared. Individual leases are better for turnover handling — losing one tenant doesn't cascade. Joint leases work for friend groups.

How does this compare to Airbnb?

Room rental produces steadier cash flow than nightly Airbnb with less management. Typical gross is 60–75% of Airbnb potential but with dramatically lower vacancy and turnover costs. Better default for first-time landlords.
