House Hacking in Denver: A $465K ADU Play

The Property

One recent open house showed a 605-sq-ft, 2BR/1BA bungalow with a separate 518-sq-ft, 1BR/1BA ADU on the same lot. Both units had their own garage and were in rent-ready condition. The zoning was E-SU-D1 (Single Unit Detached Residential with Accessory Dwelling Units), which matters: Denver law permits owner-occupants to live in the primary unit and short-term-rent the ADU through platforms like Airbnb.

Listing price: $465,000.

The Math

A buyer with $20K–$25K could use an FHA loan: $16,275 down, roughly $5,000 more for closing and ADU furnishings. The mortgage payment, including escrow, landed around $3,600 per month.

The live question: How much of that $3,600 does the short-term rental cover?

Revenue projection

AirDNA (the standard tool for Airbnb revenue modeling) estimated the ADU at $128 per night with 75% occupancy — roughly $34K annual revenue. That's optimistic if you're new to host operations. Assume 60% of that figure to account for management learning curve, seasonal dips, and occasional turnover gaps: $21K annually, or $1,750 gross per month.

After cleaning, platform fees, maintenance reserves, and property tax on the rental portion, the net monthly contribution is closer to $1,369. That offsets roughly 38% of the mortgage.

Your personal housing cost drops to $2,200 per month for living in the 2BR. Comparable rentals in the area ran $2,200–$2,500, so you're at breakeven or slightly ahead on cash flow.

Equity Math

Breakeven rent is the opening move. The real return is equity buildup.

Assuming 3% annual appreciation on a $465K property, you're gaining $13,950 per year from price movement. Add $4,400 annually from loan amortization in year one (the ratio shifts favorably each year). That's $18,350 in annual equity on a $20,000 initial investment — more than 90% ROI in year one, compounding across the hold.

Over a 10-year hold at conservative 3% appreciation (not 6–7% like luxury segments), you're looking at meaningful equity without the landlord overhead of managing two separate long-term tenants.

Value-Add Opportunities

Beyond cash flow and appreciation, this property had concrete forced-appreciation plays:

• Garage door repair/installation — high ROI, visible curb appeal
• Yard restoration and landscaping — improves both the ADU rental appeal (Airbnb guests pay more for outdoor space) and primary-unit livability

These aren't large projects; they're the kind of improvements a sweat-equity investor executes gradually while managing the rental.

Who This Works For

This deal structure suits a specific investor: someone with $20K–$25K, willing to active-manage the ADU as a host (not delegating to a property manager who'd consume half the margin), and comfortable living in the primary unit for 3–5 years while equity compounds.

If you want passive income and minimal time commitment, this deal asks too much. If you're scrappy, don't mind guest communication and turnover logistics, and can weather a slow booking month or two while you optimize your Airbnb listing, the math works.

The property doesn't require a six-figure down payment or a construction team. It requires time and operational discipline from the owner-occupant. That's the whole point of house hacking.
