Ever been handed a glossy rental projection that looks too good to be true? If you are eyeing a Seacrest Beach property on 30A, you want numbers you can trust before you write an offer. You need to see past headline revenue and understand seasonality, true operating costs, and management terms. This guide gives you a clear, step-by-step process to validate projections with confidence, using the same data and checks professional investors rely on. Let’s dive in.
Start with the right map
Seacrest Beach sits along Scenic Highway 30A in Walton County on Florida’s Gulf Coast. Before you run numbers, confirm the property’s jurisdiction, HOA, and any rental rules. Pull county records, request HOA covenants, and verify local requirements.
- Use the county site to review parcel details through the Walton County Property Appraiser.
- Check event patterns and peak travel periods on the Visit South Walton events calendar to understand demand spikes.
- Confirm state and local tax obligations with the Florida Department of Revenue’s sales tax guidance. Also review local tourist development tax requirements via Walton County and TDC resources.
Build apples-to-apples comps
You want comps that mirror your property as closely as possible. Accurate comps anchor every other part of your model.
Define your comp set
Start strict, then loosen only if needed:
- Same community: Seacrest Beach.
- Same bedroom and bathroom count, similar square footage, and comparable finishes.
- Similar amenities and access: gulf view vs interior, pool, parking, and sleeping configuration.
- If you must look outside Seacrest Beach, stay within the 30A micro-market and adjust for location and beach access differences.
Extract the right metrics
For each comp, pull at least 12 months of data, 24 months if possible. Focus on:
- ADR (average daily rate), occupancy, and RevPAR.
- Average length of stay, number of turns, and booking lead time.
- Cancellation rates and minimum-stay rules.
Cross-check across data sources
Analytics vendors use different methodologies, so triangulate:
- Compare market snapshots from AirDNA, Transparent, or Key Data.
- Validate nightly rates and minimums by searching active listings across major OTAs.
- Ask local managers for anonymized 12‑month comp sets for similar homes. Request data, not just averages.
Model seasonality month by month
Annual averages hide the 30A rhythm. Project monthly revenue using ADR times booked nights for each month.
Understand the 30A calendar
- Peak: Spring break through early August typically brings the highest ADRs and occupancy, with holiday weeks driving spikes.
- Shoulder: April to May and September to October are often solid but at lower ADRs than summer.
- Off-season: Winter months can soften, though some weekly or long-stay demand persists.
Review local festivals and holiday weeks on the Visit South Walton events calendar, then align your monthly assumptions accordingly.
Build three scenarios
- Conservative: Slightly lower occupancy and discounted ADR.
- Baseline: Market-average ADR and occupancy from your comps.
- Aggressive: Best-case ADR and occupancy seen in top comps.
Use conservative numbers for offer decisions. Incorporate minimum-stay policies in your model because 3 to 7-night minimums will change turns and booking pace.
Pressure-test the fee load
Your net is what matters. Itemize every fee and confirm how it is calculated and collected.
Management fees
Full-service STR management often ranges from 18 to 35 percent of rental revenue. Confirm whether the commission applies only to rent or also to guest-paid fees like cleaning. Note any performance tiers and marketing or technology surcharges.
Platform, cleaning, and linens
- Platform fees: Airbnb and Vrbo charge service fees, which may be deducted before owner payout or passed to the guest. Model net to owner.
- Cleaning and linen turnover: Charge per turn, not per night. High-turn months can drive costs up even with strong occupancy.
- Consumables and setup: Budget for restocking toiletries and kitchen staples and periodic linen replacement.
Utilities, HOA, insurance, and taxes
- Utilities and services: Electricity, water, internet, cable/streaming, trash, plus pool and landscaping if applicable.
- HOA or amenity fees: Include any resort, parking, and access charges.
- Insurance: Price a policy that covers short-term rental use. Review coverage types with the Insurance Information Institute.
- Taxes: Confirm Florida sales and use tax and local tourist development tax, and whether your manager registers, collects, and remits. Start with the Florida Department of Revenue’s sales tax guidance and Walton County resources.
Turns, linens, and length of stay
Turns drive real cost. The number of bookings, not just nights, determines how often you pay to clean and reset the home.
Why turns matter
Shorter stays increase the number of cleanings per month. That can reduce net revenue per night even when ADR looks strong.
Convert to a per-night cost
Turn cleaning math into a per-night equivalent so you can model accurately: total monthly cleaning and linen costs divided by total booked nights equals cleaning cost per booked night.
Watch stay rules and booking pace
Minimum-stay settings and dynamic pricing can reduce vacancy but also shift turns. Confirm typical lead times, last-minute discounting, and owner-blocked dates in manager reports.
Set smart reserves and insurance
Reserves protect your cash flow and keep the property guest-ready through high season.
What to set aside
- Operating reserve: 1 to 3 months of operating expenses.
- Maintenance reserve: Commonly 5 to 10 percent of gross revenue or a fixed amount tied to age and condition.
- Capital reserve: For larger replacements like HVAC, roof, appliances, and furniture. Many STR owners budget 3 to 5 percent of gross revenue or a fixed annual amount.
- Furnishings and linens: Plan periodic refreshes every 3 to 7 years.
Insurance and coverage
Confirm that your policy covers short-term rental use and the HOA allows it. Discuss liability limits and loss-of-income coverage with your insurer, and review best-practice guidance via the Insurance Information Institute.
Taxes and accounting
Understand the difference between deductible operating expenses and capital improvements. Review the IRS guidance in Publication 527 and reconcile your manager’s tax remittances to your records.
Read the management contract like a pro
The contract tells you how revenue becomes cash in your pocket. Ask for a working copy before you rely on any projection.
What to confirm
- Fee structure and basis: Management percentage, whether commission applies to guest-paid cleaning or taxes, and any marketing or technology fees.
- Owner payouts and reporting: Statement frequency, payment timing, calendar access, and the right to audit bookings.
- Pricing and distribution: Which OTAs the manager uses and how dynamic pricing is applied.
- Repairs and cleaning: Approval thresholds, vendor markups, linen ownership, and per-turn rates.
- Taxes and registrations: Who handles local and state tax collection and remittance.
- Termination: Notice period, exit fees, and data ownership.
Consult best practices through the Vacation Rental Management Association and align contract terms with your underwriting.
Red flags to avoid
- Commission charged on guest-paid cleaning or taxes without clear disclosure.
- Long auto-renewal with heavy termination penalties.
- Vague reporting, no calendar access, or unclear damage processes.
Build your financial model
Now translate comps and costs into a simple, reliable model you can update.
Step 1: Revenue by month
For each month, calculate ADR times booked nights. Use conservative, baseline, and aggressive scenarios and apply minimum-stay rules.
Step 2: Subtract platform fees and taxes
Remove any platform or processing fees deducted before owner payout, plus state and local taxes if they are not pass-through.
Step 3: Subtract operating expenses
Model management commission, cleaning and linen per turn, utilities, HOA, insurance, maintenance, and any marketing or tech fees.
Step 4: Calculate NOI and owner cash flow
- NOI equals gross rental revenue minus operating expenses before debt service.
- Owner cash flow after debt equals NOI minus mortgage payments.
- If you track returns, compute cash-on-cash return and an STR-adjusted cap rate with caution.
Step 5: Include reserves and test downside
Deduct maintenance and capital reserves to get realistic distributable cash flow. Then test -10 to -30 percent changes in ADR and occupancy to find breakeven.
