The price of a beach house is only the first input. A financed STR purchase also needs closing cash, immediate work, guest-ready furnishings and money left after opening. Build one dated cash ledger before choosing an offer; the hypothetical $800,000 purchase below requires $335,000 of committed cash before any separately quoted acquisition-service fee.
Worked hypothetical: $800,000 purchase, $335,000 cash plan
These invented amounts describe one planning case, not a coastal price range, lender quote or BNB Accelerator client result. Assume 25% down, no financed setup costs and no seller credits. The closing allowance includes all prepaids and escrow deposits in this example; do not add those same amounts again.
| Cash category | Assumption | Evidence to replace it |
|---|---|---|
| Down payment | $200,000 | Written loan terms: $800,000 × 25% |
| Closing charges and prepaids | $28,000 | Lender and settlement estimate, insurance and escrow details |
| Immediate repairs | $18,000 | Inspection findings and priced trade scope |
| Furnishing allowance | $42,000 | Itemized delivered-and-installed quote |
| Launch expenses | $5,000 | Photography, supplies, permits and setup invoices |
| Operating reserve held after opening | $30,000 | Monthly downside and delayed-opening cash model |
| Additional deductible liquidity | $12,000 | Actual wind/flood/STR policy terms |
| Total committed purchase and launch cash | $335,000 | Sum of these distinct categories |
The $42,000 setup line is an allowance. Replace it with an itemized coastal furnishing budget; a quote below the allowance leaves cash available, rather than proving savings already earned. Keep routine cleaning and utilities in the operating model, rather than hiding them in furniture.
Earnest money reduces the remaining wire, not the investment total
Assume $20,000 earnest money is paid earlier and fully credited on the final settlement statement. Down payment plus closing/prepaids is $228,000. The remaining closing wire is $228,000 − $20,000 = $208,000. Post-closing setup and retained reserve allocations are $107,000. The cash plan still totals $20,000 + $208,000 + $107,000 = $335,000.
The CFPB Closing Disclosure explainer distinguishes cash to close from closing charges and money already paid. Match the actual statement and loan product with your closing professional. If an inspection or insurance invoice was paid outside closing, mark it paid in the same category; do not add it twice.
Price the coastal exposures before releasing the deposit
FloodSmart explains that most homeowners policies exclude flood damage. Obtain quotes for the actual rental use and location, with wind/flood coverage, contents, deductibles, exclusions and interruption terms shown separately. A deductible is cash exposure; an insurance premium is an expense. Neither guarantees reimbursement for a closed calendar.
- Confirm parcel rental use, permitted capacity and HOA terms for the buyer.
- Price roof, HVAC, moisture, exterior corrosion and drainage defects with appropriate specialists.
- Ask whether utilities, storage, beach access or parking add recurring or one-time costs.
- Keep operating and deductible reserves distinct in this example; if your own reserve covers both, reconcile the overlap instead of funding it twice.
Use the existing all-in buyer budget and launch-delay cash plan for the broader method. The maximum simultaneous cash shortfall matters more than a generic percentage reserve.
Turn the ledger into a purchase decision
Request the actual service fee and scope before treating the cash plan as complete. Add that fee and all unquoted third-party costs to the property ledger. Record each amount, payment date, source, owner and whether it remains an estimate.
Proceed to a shortlist only when financing, legal use and quotes fit the cash you can commit while preserving the agreed reserve. If the plan spends every dollar at closing, lower the purchase scope or pause the search. A seller’s projected revenue does not fund your opening invoices.
Frequently asked questions
Is the down payment the full cost of buying a beach-house STR?
No. Include closing/prepaid cash, repairs, furnishings, launch and reserves, plus separately quoted service or vendor fees. The example uses invented assumptions.
Do I add earnest money to cash to close?
Count credited earnest money once. It is part of total invested cash and reduces the remaining settlement wire when the final statement applies the credit.
Is $335,000 a minimum BNB Accelerator buyer budget?
No. It is the total of one hypothetical purchase ledger, not a company eligibility threshold or a quote.
