Rental arbitrage is the one strategy on this list that requires no property ownership and very little capital — a deposit, furnishings, and a landlord willing to permit subletting. That accessibility is why it attracts people, and the absence of an owned asset is why it behaves differently from every other strategy here: there is no equity, no appreciation, and nothing to refinance.
How the spread works
Lease an apartment at $2,000 a month with written permission to sublet. Furnish it for $8,000–$15,000. List it nightly, and at $150 a night with 70% occupancy it grosses roughly $3,150 a month. After platform fees, cleaning, utilities, supplies and software, perhaps $700–$1,000 of margin remains. The model is thin per unit by design, which is why operators run several — and why one bad month across a portfolio hurts.
Written permission is the entire foundation
Most standard residential leases prohibit subletting. Operating without explicit written consent is a lease breach that can end in eviction, loss of the furnishing investment, and a judgment. Get it in the lease itself, not as a verbal understanding with a leasing agent who may not be there next year. A landlord addendum that names short-term rental specifically is what you want; silence in the lease is not permission.
Local rules are the bigger constraint
City and county short-term rental regulation has tightened almost everywhere, and many jurisdictions now require the operator to be the owner, or to occupy the property, or cap permits by district. Some ban non-owner-occupied short-term rentals outright. A lease permitting subletting does not override a municipal rule. Check the ordinance before signing anything — this is where the capital actually gets lost, more often than through poor occupancy.
What you are exposed to
You carry the full lease obligation regardless of bookings. Platform policy changes, an algorithm shift or a regulatory change can cut revenue overnight while rent stays fixed. Seasonality is sharper than in long-term rental. And there is no asset underneath — if the strategy stops working, the furnishings are the only thing to sell, and they sell for a fraction of cost.
Why owners end up buying instead
The arbitrage operator captures the operating spread and none of the equity. Successful operators frequently conclude that if the numbers work as a tenant, they work better as an owner — the same nightly revenue then services a mortgage, builds principal, and captures appreciation. Short-term rental investing covers that version, and DSCR lenders will underwrite short-term rental income using trailing platform statements on properties in established markets.
Rental Arbitrage FAQ
It depends on two things: whether your lease permits subletting in writing, and whether local ordinances permit non-owner-occupied short-term rentals. Both have to be satisfied.
Far less than buying — typically deposits plus $8,000–$15,000 of furnishings and setup per unit, with no down payment.
Often a few hundred to around a thousand dollars a month per unit after all costs, which is why operators scale to multiple units. Margins vary sharply by market and season.
Regulatory change. A city ordinance restricting non-owner-occupied short-term rentals can end the business while the lease obligation continues.
Yes. Standard renters insurance does not contemplate commercial short-term rental use. Short-term rental operator policies exist and platform-provided coverage should not be relied on alone.
Buying captures equity, appreciation and principal paydown alongside the operating margin. Arbitrage captures only the margin, with a far lower entry cost.
