Part A: House Hack Checklist

Step 1: Property type and legal check

House hacking requires a property with at least two legally distinct living spaces — a duplex, triplex, fourplex, or a property with a permitted accessory dwelling unit (ADU).

An owner-occupant loan on a property you do not intend to occupy is mortgage fraud, not a strategy. Only use owner-occupied financingOwner-Occupied FinancingMortgage financing available when the borrower plans to live in the property as a primary residence, often with lower down payment options than investor loans.Read more in the glossary if you genuinely plan to live in the property.

Step 2: Market demand signals (census)

Even though you are partly occupying the property, the rental units need a real tenant market. The same census dataCensus DataGovernment-collected data on population, income, vacancy rates, owner/renter ratios, and demographics at the ZIP code or tract level.Read more in the glossary signals apply.

Step 3: Net housing cost — the primary metric

The goal of house hacking is to reduce your personal housing expense. The primary metric is net housing costNet Housing CostThe owner-occupant's monthly housing cost after subtracting rent collected from other units, bedrooms, or accessory dwelling units.Read more in the glossary: your monthly payment minus rent collected from other units.

Net housing cost = Total PITI + Operating expenses − Rental income from other units

PITI includes principal, interest, taxes, and insurance. Operating expenses include maintenance, management (even if you self-manage), reservesCapital Reserves (CapEx)Monthly savings set aside for large, infrequent expenses: roof, HVAC, plumbing, appliances. Often 5–10% of gross rent.Read more in the glossary, and utilities you cover.

Use the house hack analysis calculator to model the net housing costNet Housing CostThe owner-occupant's monthly housing cost after subtracting rent collected from other units, bedrooms, or accessory dwelling units.Read more in the glossary at your specific financing terms. For market rent data to estimate the other units' income, Apartment List's national rent report provides metro- and city-level median rent trends.

Step 4: Expense inputs

A common mistake is including only the mortgage and forgetting that property taxes, insurance, and maintenance apply to the whole building, not just your unit.

Step 5: Model the future full-rental phase

Owner-occupied loan requirements typically require you to live in the property for at least one year. After that, you can move out and rent your unit, converting the house hack to a full rental.

Model both phases before you buy. Some properties work well as house hacks but produce weak cash flow as standalone rentals. Knowing this ahead of time lets you plan your exit.

When you refinance into an investor loan and begin collecting rent on all units, consult IRS Publication 527 (Residential Rental Property) for guidance on deductible expenses, depreciation, and passive income rules. Fannie Mae's rental income guidelines also govern how much of the rental income lenders will count when underwriting the new loan.

Part B: Short-Term Rental Checklist

Step 1: Regulation check — do this first

Short-term rentalShort-Term / Vacation RentalRenting a property on a nightly or weekly basis via platforms like Airbnb or VRBO instead of a traditional long-term lease.Read more in the glossary regulations have tightened sharply in many markets. Platforms, cities, counties, and HOAs all have their own rules, and they do not align.

Step 2: Market demand signals

Unlike long-term rentals, STR occupancyOccupancy RateThe percentage of time or units that are occupied. For short-term rentals, it is often measured as booked nights divided by available nights.Read more in the glossary data is not publicly available in census form. You are estimating based on platform data and market-level signals.

Step 3: Break-even occupancy — the primary metric

The central question for a short-term rental is: at what occupancy rate does this property cover all its expenses? That is break-even occupancyBreak-Even OccupancyThe minimum occupancy rate required for the property to cover all expenses including debt service.Read more in the glossary.

Break-even occupancy = Total monthly expenses ÷ (Nightly rate × Days available)

Total monthly expenses include PITI, management (STR platforms typically charge 3% of booking + host fees, plus 20–30% if using a local co-host), cleaning, restocking, insurance (STR-specific coverage), and reserves.

Use the break-even occupancy calculator to set this threshold.

Step 4: Revenue estimate — use conservative inputs

Average daily rateAverage Daily Rate (ADR)The average nightly revenue earned by a short-term rental for booked nights, before or after specific fees depending on the analysis.Read more in the glossary (ADRAverage Daily Rate (ADR)The average nightly revenue earned by a short-term rental for booked nights, before or after specific fees depending on the analysis.Read more in the glossary) and occupancy rateOccupancy RateThe percentage of time or units that are occupied. For short-term rentals, it is often measured as booked nights divided by available nights.Read more in the glossary together determine gross revenue. Both are hard to estimate accurately without live market data, and both tend to be overstated by sellers and STR coaches.

ADR and occupancy data from AirDNA, Rabbu, or similar platforms can give market-level estimates. Always treat them as inputs for a range, not guarantees.

Step 5: Full expense stack for STR

Short-term rental expenses run significantly higher than long-term rentals. The common mistake is modeling STR revenue against long-term rental expenses.

Step 6: The long-term fallback check

Before finalizing any STR analysis, confirm the property works as a long-term rental if the STR strategy fails — regulation change, platform delisting, or poor occupancy.

A property that requires STR economics to avoid negative cash flow is a speculative bet, not a safe investment.

Pass/fail summary

FAQ

Can I use an FHA loan to house hack?

Yes. FHA loans allow as low as 3.5% down on owner-occupied properties of up to four units. You must occupy one unit as your primary residence. The rental income from other units can be counted toward qualifying income in some cases. Confirm with your lender.

What occupancy rate should I use for an STR analysis?

Start with the market rate from platform data and apply a 10–15 point haircut for your own estimate. New listings earn lower occupancy while building reviews. Seasonal markets may average 40–50% over a full year even if peak months hit 90%. Do not use the best month as your benchmark.

Should I hire a co-host or manage the STR myself?

Co-hosts charge 20–30% of gross revenue but handle check-in, cleaning coordination, guest communication, and maintenance. Self-managing saves that cost but requires real time. Model the expense either way — if the deal only works because you self-manage, factor in what your time is worth.

What happens if regulations change after I buy?

This is one of the most common risks in STR investing and the main reason the long-term fallback check matters. If your STR is banned, can you rent long-term and still cover costs? If yes, your downside is managed. If no, you are exposed to the regulatory risk with no exit.

Does house hacking work in high-cost markets?

It can, especially with owner-occupied financing on a 2–4 unit property. The math works when rental income from other units meaningfully reduces your net housing cost compared to paying full rent. In very high-cost markets, you may still have a high net housing cost — but it may still be lower than comparable rent and is building equity at the same time.
