Rental arbitrage means you lease a property from a landlord at a fixed monthly rent, furnish it, and host short-term or mid-term guests, keeping the spread between guest revenue and your rent. Most operators I train start one unit for $3,000 to $8,000 all-in, which is far less than the down payment on the same property. You do not own the building, you do not carry a mortgage, and you do not wait three years to save a deposit. You run a hospitality business inside a lease agreement.
There are property owners right now posting on Reddit and in local landlord groups asking for someone to take over a furnished unit under a sublease arrangement. You could be that person. What follows is how the model works, what it costs, the three numbers every deal hinges on, and the failure modes that end most first attempts inside six months.
Rental Arbitrage in One Sentence
You pay rent. Guests pay you more than rent. You keep the difference after cleaning, platform fees, supplies, and furniture amortization.
That is the whole model. Everything else is execution: which market, which unit, what lease language, how fast you get reviews, and how disciplined you are about the numbers before you sign anything.
Two things separate arbitrage from ownership. First, your downside is capped at the remaining lease term plus the furniture you bought, not the market value of a mortgaged asset. Second, your upside is capped too. You will never refinance an arbitrage unit or sell it for appreciation. Arbitrage buys you operating cash flow and operating experience. I have watched many operators use the cash flow from two or three arbitrage units to fund the down payment on the first property they actually own. That is the honest role of this model in a portfolio.
The IRS treats the income accordingly. Rent you collect is rental income and the rent you pay the landlord is a deductible expense, reported per the rules in IRS Publication 527; if you provide substantial services the activity can be treated as a business instead, which changes your self-employment tax picture. Decide that with your CPA before your first tax year closes, not after.
Why Property Owners Want This Arrangement
This is the part most people get wrong. Arbitrage does not require you to talk a reluctant landlord into something. There are landlords actively looking for professional operators.
A Dallas owner posted last month offering a fully furnished unit for a lease takeover, specifically asking for an experienced Airbnb operator. He did not want another standard tenant. He wanted someone who would treat the unit like a business, because a well-run short-term rental usually means faster payment, better upkeep, and a single point of contact who answers the phone.
The landlords most open to the arrangement share a pattern:
They have carried a vacancy for 30 days or more and are watching rent evaporate.
They own a furnished unit, often a former corporate rental, that does not fit the standard 12-month tenant pool.
They own in a tourism, medical, or university market where turnover is constant anyway.
They have been burned by a tenant and prefer a business counterparty with insurance and a cleaning crew.
The conversation is not "can I sublease your property." It is "I will pay your rent on the first of the month, carry a million dollars of liability coverage, professionally clean the unit weekly, and give you the right to inspect quarterly." That is a different pitch, and most owners will at least hear it out. Expect a stack of noes before your first yes. That ratio improves once you can show a landlord your existing listing, your review score, and 12 months of on-time payment history.
The Three Numbers That Make Arbitrage Profitable
Before you sign a lease, you need three numbers. They decide the deal, not your enthusiasm for the neighborhood.
Number 1: your master lease rate. What you pay the landlord monthly. Every other number is measured against it.
Number 2: your projected nightly rate. Use platform search in your target market, filtered to the same property type, bedroom count, and guest capacity. Pull weeknight and weekend rates for eight to ten comparable listings that have recent reviews. Average them, then subtract 10% because your listing has no review history yet.
Number 3: your occupancy assumption. In your first 90 days, plan for 55% to 65%. As reviews accumulate, that should climb toward 70% or better in a market with real demand. Underwrite at 60%. If the deal does not work at 60%, do not sign it.
Here is the base case, worked all the way through. You lease a two-bedroom in a mid-tier market for $1,500 a month, at a $120 nightly rate and 60% occupancy, which is 18 nights of a 30-day month. Gross revenue is 18 × $120 = $2,160. Rent is $1,500. Cleaning at $45 a turn for six turns is $270. Platform fees, modeled here at an illustrative blended 10% of gross, are $216 (Airbnb's host service fee is typically about 3% under its split-fee structure and 14% to 16% under host-only pricing, so check which applies to your listing). Consumables and supplies run $80. Total costs are $2,066, leaving $94 a month. That deal is not worth your time. It has no margin for a slow February, a broken HVAC, or one chargeback.
The table below shows what fixes it. Nothing here is a projection of your market; it is arithmetic on the inputs above.
Scenario | Nightly rate | Nights booked | Gross | Rent | Cleaning + fees + supplies | Net / month |
|---|
Base case | $120 | 18 | $2,160 | $1,500 | $566 | $94 |
Raise ADR to $165 | $165 | 18 | $2,970 | $1,500 | $647 | $823 |
Hold $120, lease at $1,150 | $120 | 18 | $2,160 | $1,150 | $566 | $444 |
$165 ADR at 70% (21 nights) | $165 | 21 | $3,465 | $1,500 | $742 | $1,223 |
Cleaning scales with turns and platform fees scale with gross, which is why the fee column moves in each row. The pattern is consistent across every market I have underwritten: a unit clears when gross revenue is roughly 2x the lease rate. At 1.4x you are working for free. Below that you are subsidizing a landlord's mortgage.
Two more numbers belong in your model even though they do not change the monthly line. Furniture is a real cost spread over the lease, so divide your furnishing spend by the lease term and carry it as an expense. And lodging tax applies to short stays in most jurisdictions; Texas, for example, charges a state hotel occupancy tax on rooms costing $15 or more per day, with city and county hotel taxes stacked on top, and those local taxes applying to rooms costing $2 or more per day. Platforms collect and remit some of these for you and not others, so confirm which line items are on you before you price.
Startup Costs and the Lease Language Process
Here is the real list, in the order I have people execute it. Each step has a gate; do not move to the next one until the current one clears.
Pick a market with existing short-term or mid-term demand. You are meeting demand, not creating it. Look for a hospital, university, convention venue, military base, or tourism draw within 20 minutes.
Read the city ordinance before you look at a single unit. Confirm short-term rentals are permitted at the address type you want and find out what the permit costs. Budget roughly $50 to $300 a year in most cities, and treat a hard ban as a closed market.
Run the three-number analysis on five properties. Write the numbers down. Kill any deal that does not clear at 60% occupancy.
Approach owners with the guaranteed-rent-plus-management pitch. Track your outreach so you know your real ask-to-yes ratio.
Get sublease permission in writing in the lease itself. Verbal permission is worth nothing.
Bind insurance before move-in: a renters policy with a short-term rental endorsement, or a commercial short-term rental policy, with liability at $1,000,000.
Furnish and photograph in one week. Natural light, wide angle, every room, plus a shot of the exterior entry so guests can find the door.
List on Airbnb and Furnished Finder the same week you take possession. Price your first three bookings 10% to 15% under comparable listings to start the review engine.
Costs for a one- or two-bedroom unit, at the ranges I see operators actually pay:
Line item | Typical range | Notes |
|---|
First month rent | $1,000–$2,000 | Paid at signing |
Security deposit | $1,000–$2,000 | Often one month; sometimes negotiable to half |
Furniture, mattresses, linens | $2,500–$4,500 | Buy beds and seating new, everything else used |
Kitchen, consumables, safety items | $400–$800 | Includes smoke and CO alarms, first aid, fire extinguisher |
Photography | $0–$350 | Skip if you can shoot well in daylight |
STR permit and business filing | $50–$500 | Varies by city and entity choice |
Insurance (first quarter) | $150–$400 | STR endorsement or commercial policy |
All-in start | $3,000–$8,000 | Lower end assumes a partly furnished unit |
No LLC is required to start, though the SBA's guide on choosing a business structure is the right 20-minute read before you decide between a sole proprietorship and an LLC for liability separation. No business credit, no real estate license, no down payment.
The sublease clause is the single document that decides whether you have a business or a problem. Negotiate language close to this: "Tenant is permitted to sublease the property for short-term stays via platforms including Airbnb, VRBO, and Furnished Finder, provided tenant maintains a minimum liability insurance policy of $1,000,000 and notifies landlord of any guest damage within 24 hours." Add the lease term, renewal terms, and who pays for what repair. If a landlord will not put it in writing, the answer is no. Platforms will not protect you against your own landlord, and a verbal arrangement ends the first week a neighbor complains.
Objections, Risks, and Failure Modes
"Won't landlords always say no?" Some will. The ones with vacancies, furnished units, or turnover-heavy markets often do not. Ask directly, lead with guaranteed rent and professional management, and expect to work through 15 to 25 conversations for your first yes.
"Is this legal?" In most markets, yes, when your lease permits subleasing and local rules allow short stays at that address. Cities regulate this at the property level, so a permitted unit two blocks away tells you nothing about yours. Pull the ordinance, get the permit, keep the receipt.
"What if I can't fill it?" You still owe rent. That is the core risk and it is not passive income: you manage pricing, messaging, cleaning, and maintenance every week. The trade is that your worst case is a few months of lease payments and a furniture write-down, not an owned asset that drops 20% while you hold the note.
The failure modes I see most often, in order:
Signing a deal that only works at 80% occupancy. Nearly every blown arbitrage unit was underwritten on a best case.
No reserve. Hold two months of rent in cash before you list, separate from your furnishing budget.
Ignoring the ordinance and getting shut down in month four with $6,000 of furniture in a unit you cannot rent nightly.
Refusing to pivot to 30-plus-day mid-term stays when nightly demand softens. A mid-term booking at 85% of your nightly math with one turn a month is often the better business.
Underpricing cleaning. If your cleaner quits in July you will pay double, so build the real rate into your model from day one.
If you want a second set of eyes on a specific unit before you sign, book a complimentary one-on-one diagnostic call and bring your three numbers. The call is free. If you want the written version afterward, the $997 action plan lays out the market, the lease terms, and the operating targets for your unit.
Your First 30 Days: KNOW / DO / TRACK
KNOW:
Your deal only works if nightly rate × projected occupancy comfortably exceeds rent plus operating costs. Target gross revenue near 2x rent. Run the math before you sign.
Rental arbitrage is a hospitality business, not a passive investment. You are the operator.
Your first 90 days build reviews, not profit. Price competitively until you hold 10 or more reviews.
DO:
Identify your target market and run the three-number analysis on five properties.
Find landlords with vacant or furnished units. Craigslist, Facebook Marketplace, local landlord groups, and direct outreach all work.
Negotiate sublease permission into the lease, or walk away.
Furnish for $3,000 to $8,000 and photograph the unit properly.
List on Airbnb and Furnished Finder the week you take possession, and accept your first three bookings 10% to 15% below comparable listings.
TRACK:
Net cash flow per month: gross revenue minus rent, cleaning, platform fees, and supplies.
Occupancy rate: 60% in month one, 70% or better by month three.
Average daily rate: raise it $5 to $10 for every five new reviews.
What to Do Next
If you have been waiting on a down payment to start, stop waiting. This model asks for the right landlord, correct arithmetic, and operator discipline. It does not ask for ownership.
Pick one market this week. Run five deals through the three numbers. Send ten landlord messages. That sequence has produced more first units among the operators I have trained than any amount of further research. Your first unit is a lease agreement away.
Frequently Asked Questions
How much money do I need to start rental arbitrage?
Plan for $3,000 to $8,000 for a one- or two-bedroom unit. That covers first month rent, deposit, furniture, supplies, permit, and insurance. Hold an additional two months of rent as reserve so a slow first month does not end the business.
Is rental arbitrage legal?
It is legal in most markets when two conditions hold: your lease explicitly permits subleasing for short stays, and local rules allow short-term rentals at that address. Cities regulate by property and zone, so check the ordinance for your exact unit and pull the permit. Operating on verbal landlord permission is the fastest way to lose the unit.
How do I get a landlord to agree to a sublease?
Lead with what solves their problem: rent paid on the first, $1,000,000 liability coverage, weekly professional cleaning, and quarterly inspection rights. Target owners with current vacancies or furnished units. Expect 15 to 25 conversations before your first yes, and get the permission written into the lease.
What occupancy rate should I underwrite?
Use 60%. First-quarter reality for a new listing is usually 55% to 65% while reviews accumulate, climbing toward 70% or better afterward in a market with real demand. If a deal only clears at 75% or 80%, it is not a deal.
Do I need an LLC for rental arbitrage?
You can sign a lease and host as an individual, and many operators start that way. An LLC is about liability separation and how your income is reported, not about permission to operate. Read the SBA structure guide, then decide with a CPA before your first tax year closes.
Is rental arbitrage better than owning a rental property?
They do different jobs. Arbitrage gets you cash flow and operating experience in weeks with a capped downside and no mortgage, but no appreciation or equity. Ownership builds equity and takes a down payment and months of underwriting. Many operators run two or three arbitrage units and use the cash flow to fund their first purchase.
