There is no universal earnest-money percentage that makes a short-term rental offer safe. A larger deposit may help a seller take your offer seriously, but the buyer's real question is how much cash to commit before you can verify that the address can legally operate, the loan and insurance work, and the revenue claim survives diligence. Set the amount alongside the contract's deposit deadline, contingency dates, and release rules. If the seller wants more money at risk, ask what documented protection and access you receive in return. Book a call to structure your STR purchase offer around the actual deal risks.
Start with the contract, not a percentage
The CFPB defines earnest money as a good-faith deposit under a signed purchase agreement. It says the deposit may be applied to closing costs or the down payment when the sale closes, may be returned after a permitted termination, and may be forfeited when a buyer fails to perform in good faith. Your signed agreement and local law determine the details. Do not treat a quoted percentage or a verbal promise as a refund rule.
Ask your local licensed agent and attorney for recent comparable offers in the exact submarket, the seller's requested amount, the escrow holder, and the date money must be delivered. Ask the lender how the deposit will appear in your cash-to-close accounting; CFPB disclosure guidance treats a purchase deposit as a separately disclosed amount. A deposit is not extra profit to the seller at a successful closing, but it does temporarily tie up liquid cash and can become disputed or forfeited under contract terms.

Put STR-specific proof dates beside the deposit deadline
Build a one-page calendar with four columns: issue, person responsible, documentary proof, and the last contract date to act. For legal use, seek an address-specific answer from the permitting authority and review any HOA or condominium documents. For an operating rental, request platform payout exports, booking history, seller expense records, and evidence of who controls future reservations. For financing, ask the lender to assess this property and intended rental use, not just your borrower profile. Get property- and STR-use-specific insurance indications. These checks may take different amounts of time; the contract must give you enough time to get answers before protection expires.
A large deposit cannot cure a missing permit, nontransferable rental approval, or loan that will not close. Conversely, a smaller deposit with no meaningful diligence rights is not automatically safe. Map every unresolved fact to a contract condition, document-delivery requirement, or date for written objection that local counsel confirms is enforceable. The STR diligence-timing guide addresses how long that review may need; the early-release guide addresses the separate question of paying escrowed money to a seller before closing.
| Offer lever | What it can signal | Buyer check before using it |
|---|---|---|
| Larger initial deposit | Commitment and available liquidity | Can you still fund inspections, financing, closing and launch reserves; when could it be forfeited? |
| Smaller initial deposit | Lower cash tied up during diligence | Is the offer still competitive with this seller; are other terms stronger? |
| Additional deposit after a milestone | More commitment after specified evidence arrives | Is the milestone objective and does counsel approve the timing and refund language? |
| Shorter diligence period | Potentially faster seller certainty | Can the permit, HOA, lender, insurer and revenue checks actually finish before expiration? |
Compare deposit structures with a cash-at-risk worksheet
Write down the proposed deposit, the cash available for diligence, expected cash to close, and launch reserve. For each failure mode—STR use denied, financing rejected, seller revenue unsupported, unacceptable insurance, or material property condition—record whether you have an express contractual exit, its deadline, how notice must be delivered, and what happens to the deposit. This is a legal-risk worksheet, not a claim that every contingency guarantees an immediate refund. The CFPB warns that a buyer unable to close may lose the deposit and should review the financing contingency and contract with counsel.
Illustrative numbers only: suppose two offer structures on the same $500,000 candidate property are a $5,000 initial deposit with a later $10,000 increase after named STR-use and financing evidence, or $15,000 due immediately. Both can reach $15,000, but the amount exposed before evidence is different. Do not assume either structure is available, competitive, or refundable; the seller must agree and the signed terms control. If the second structure leaves too little cash to pay for diligence or launch, its headline strength may conceal a weaker purchase plan. Run both through the cash-needed-to-buy model and ask the local transaction team what the seller actually values.
Make the offer decision before wiring funds
Proceed when the deposit fits your liquidity, the seller accepts the structure, and each unresolved STR purchase risk has an achievable proof and contract deadline. Renegotiate the amount, timing, or contingency language when the seller wants a stronger signal than your evidence calendar can justify. Delay the offer if you cannot yet identify who will verify legal STR use or whether the lender will finance the planned use. Reject a requirement to put material money at risk before a decisive issue can be checked, if the deal only works by assuming the issue resolves favorably.
Before sending money, independently confirm the escrow recipient and instructions using a trusted phone number, follow your title or closing professional's secure process, and keep proof of delivery. Have a qualified local attorney review deposit timing, notices, remedies, and any proposed nonrefundable or early-release provision. Book a call to compare STR offer terms and the underlying acquisition case.

Frequently asked questions
Is there a required earnest-money percentage for an STR purchase?
No universal percentage sets the right deposit. Local practice, seller priorities, buyer liquidity, and the signed contract matter. Ask local professionals for comparable offers and review the actual terms.
Should I offer more earnest money to beat another STR buyer?
Only if the added commitment fits your cash plan and the contract leaves realistic time and rights to verify STR use, financing, insurance, revenue, and condition. Compare the whole offer, not just the deposit.
Does a larger deposit mean I cannot cancel after a failed STR permit check?
The deposit size alone does not answer that. Your contract, notice procedure, deadlines, and local law govern cancellation and refund. Have local counsel review the specific STR-use condition.
Can I increase earnest money after diligence?
You can propose a staged deposit, but the seller must agree and the written contract must define the milestone, timing, escrow treatment, and consequences. Ask counsel to draft or review it.
Questions to resolve before committing to this purchase
How do I compare STR earnest money with liquidity limits?
Calculate the deposit's cash timing alongside inspection and financing expenses. A stronger offer should not leave the buyer unable to fund the remaining diligence work.
How do I verify STR earnest money escrow instructions?
Confirm the authorized holder and payment instructions through a trusted established channel. Have the transaction team explain receipts and deadlines before transferring money.
How do I review STR deposit refund conditions before an offer?
Ask counsel to identify the actual protections, notice requirements and deadlines. Earnest money is not universally refundable simply because a buyer changes investment preferences.
How do I cap STR deposit exposure when waiving protection?
List the evidence still unresolved and cash potentially at risk. Have counsel explain the proposed waiver before committing a larger deposit to an unsupported purchase case.
How do I separate STR earnest money from total cash to close?
Show the deposit as already-paid price cash when the closing team applies it. Avoid adding it twice to equity or treating it as an extra expense.
Record the evidence, responsible reviewer, cash effect and transaction deadline for any unresolved item. Bring those findings to the STR acquisition call before deciding whether to proceed, revise the offer or exercise available contract protection.
