Thinking about buying a 2-bedroom condo in Miramar Beach to use as a short-term rental? Your return will come down to the numbers you set on day one. Underwriting can feel complex, especially with coastal seasonality, HOA budgets, and taxes to consider. This guide shows you how to build a clear, defensible pro forma for a Miramar Beach 2BR using local seasonality, realistic expenses, and comps, so you can invest with confidence. Let’s dive in.

Why Miramar Beach is unique

Miramar Beach sits on Florida’s Emerald Coast, where demand is highly seasonal. Summer and Spring Break weeks bring strong weekly bookings, shoulder seasons still perform but at lower ADRs, and winter is quiet outside of holiday weeks. Unit type matters. Beachfront or gulf-view 2BRs with pool and direct beach access often command premium ADR and stronger occupancy versus interior or older properties. Your comps should mirror your unit’s building, location, and amenities.

Start with rules and taxes

Before you model revenue, confirm compliance. You do not want surprises after closing.

• Walton County governs short-term rentals in Miramar Beach. Verify any county permitting, safety, noise, and occupancy rules, plus required business registrations.
• Florida state sales tax applies to short-term rentals, and Walton County levies a Tourist Development Tax. Confirm current rates and filing steps with the Florida Department of Revenue and the Walton County Tax Collector or Tourist Development Council.
• Some platforms collect and remit certain taxes in specific jurisdictions. Confirm what is and is not collected for Walton County so you set up filings correctly.
• Review your HOA bylaws for rental rules, minimum stays, and any guest policies or fees that affect operations.

Model revenue by month

Treat revenue as a monthly model, not a single annual average. The Emerald Coast’s seasonality is too pronounced for one-blend metrics.

Average daily rate (ADR)

• Pull ADR from true comps: same building or within about a mile; 2 bedrooms, similar baths, sleeps count, view, and amenities.
• Account for condition and upgrades. Newly renovated or designer-furnished units tend to achieve higher ADR.
• Understand pricing conventions. Many Miramar Beach owners price weekly in summer. Cleaning fees are typically passed to guests and should sit outside ADR in your model.

Occupancy

• Use occupancy from the same comps over 12 to 36 months. Model month-by-month, not just an annual average.
• Expect the highest occupancy from late May through August, with added peaks in March and April for Spring Break and on select holiday weeks.
• Channel mix matters. Direct bookings, Airbnb, Vrbo, and local managers can yield different occupancy and ADR results.

Seasonality buckets

Create three buckets to make monthly modeling easier:

• Peak: June to August
• Shoulder: April to May, September to October
• Off-peak: November to March, with holiday bumps

Length of stay and minimums

• Weekly minimums are common in peak season and can stabilize turnover and calendar efficiency.
• Shorter stays may help in the off-season, but weekday demand may be thinner.

Distribution fees

• Host fees, payment processing, and any channel manager costs reduce effective revenue. Decide whether you will record ADR as gross of platform fees and show host fees below, or model net ADR.

Itemize all expenses

A complete expense stack is critical for accurate cash flow. Build from fixed to variable, then reserves.

Fixed costs

• HOA dues: For condos, HOA is a major fixed line item. Check inclusions like building insurance, reserves, cable/Internet, and common utilities.
• Property taxes: Use the Walton County Property Appraiser for assessed value and millage rates. Annual taxes change with assessed value and millage.
• Insurance: Price short-term rental coverage suited for coastal Florida. Include wind or hurricane endorsements and consider higher liability limits or an umbrella policy.
• Utilities: Electricity, water/sewer, Internet and cable. Many guests expect high-speed Internet and streaming-ready TV.
• Management: Full-service short-term rental management typically ranges from 18 to 35 percent of gross rental revenue. Clarify whether the fee is calculated on gross or net and what services are included.
• Marketing/OTA tools: Budget for channel managers or direct-booking expenses if used.
• Accounting/legal/permits: Include business licenses, rental registrations, and bookkeeping.

Variable and per-stay costs

• Cleaning: Usually passed to the guest, but you still need to model the expense and the number of turnovers. Prices vary by unit size and season. Expect surcharges during peak weeks and allow for periodic deep cleans.
• Supplies and consumables: Linens, replacements, toiletries, coffee, and restocking.
• Maintenance and repairs: Set a routine reserve. Many operators hold 5 to 10 percent of gross revenue or a set monthly amount for a 2BR to cover wear and tear.
• Pest control and any non-HOA services: Include as needed.

Taxes and remittances

• Sales and transient tax: Florida sales tax applies to short-term rentals, and Walton County imposes a Tourist Development Tax. Confirm current combined rates, who collects, and your filing schedule.
• Income tax: Model property performance pre-tax, then review investor-level tax treatment with your advisor.

Capital expenditures and reserves

• CapEx and replacement: Budget 5 to 10 percent of gross revenue annually for larger items and replacements, adjusted for property age and amenity exposure.
• Furnishings: Amortize sofas, beds, rugs, TVs, and outdoor furniture over reasonable lifespans to avoid lump-sum surprises.
• Damage coverage: Decide on security deposits or damage protection insurance and record premiums and expected claims net.

Build your pro forma

Lay out your 12-month model from the top line down to cash flow. Keep your assumptions transparent.

• Revenue by month: Booked nights = days in month multiplied by monthly occupancy. Monthly revenue = monthly ADR multiplied by booked nights.
• Less platform fees and any listing costs.
• If you pass cleaning fees to guests, show cleaning revenue separately from cleaning expense for clarity.
• Net rental revenue plus other income: Pet fees, parking, linen rentals if applicable.
• Operating expenses: Management, HOA, utilities, insurance, property tax, cleaning, maintenance and supplies, marketing and channel tools, permits, and accounting.
• Net Operating Income (NOI): Gross operating income minus operating expenses.
• Reserves: CapEx and replacement reserves set aside monthly.
• Debt service: If financing, add principal and interest to see leveraged cash flow.
• Returns: Cash-on-cash, cap rate, and Debt Service Coverage Ratio.

Run scenarios and sensitivities

Your break-even and risk picture matter as much as your base case.

• Base case: Best-estimate ADR and occupancy by month using comps and manager input.
• Conservative: Reduce ADR by 10 to 20 percent and occupancy by 10 to 20 percent. Keep fixed costs the same.
• Aggressive: Increase ADR by 10 to 15 percent and occupancy by 5 to 10 percent, assuming top-tier marketing and guest experience.
• Shocks: Model downtime during hurricane season, potential regulatory changes, or a demand slowdown.
• Sensitivity matrix: Vary ADR and occupancy together and track NOI, cash flow after debt service, DSCR, and cash-on-cash.
• Break-even occupancy: Fixed annual costs plus annual debt service, divided by ADR minus variable cost per night, converted to a percentage of the year.
• Turnover sensitivity: Compare peak-season weekly minimums against nightly availability year-round. Weekly rules can reduce cleaning costs and enhance calendar efficiency but may lower flexibility.

Pick credible comps

Your underwriting is only as strong as your comp set.

• Geography: Same building first, or within about 0.5 to 1 mile in Miramar Beach.
• Configuration: True 2BRs, similar baths, sleeps count, and square footage.
• Amenity parity: Gulf-front or gulf-view, pool access, elevator, in-unit laundry, and parking.
• Condition: Renovated units should be adjusted upward relative to dated units.
• Channels and policies: Note cancellation policies and platform differences that influence occupancy.
• Quality checks: Remove outliers with unusual discounts or long-term, below-market bookings. Ensure monthly ADR and occupancy align with Emerald Coast seasonality and local event weeks.

Quick checklist and next steps

Use this shortlist to move from interest to a defensible pro forma fast.

• Property specifics: HOA dues and inclusions, rental rules, minimum stays, floor and view, upgrades, furniture inventory, sleeps count, parking, and pet policy.
• Market data: Pull a 2BR Miramar Beach dataset from a recognized STR platform, compile 6 to 12 active comps from major channels, and request performance averages from 1 to 3 local managers.
• Taxes and compliance: Confirm Walton County Tourist Development Tax details, Florida sales tax application and collection practices, and any county registration requirements.
• Vendor quotes: Cleaning per-turn price, full insurance quotes including wind coverage, management fee options, and trusted local trades for maintenance.
• Build and test: Model monthly revenue and expenses, include reserves, and run base, conservative, aggressive, and shock scenarios. Calculate break-even occupancy and DSCR.
• Validate locally: Review your assumptions with a Miramar Beach property manager or experienced investor before you finalize.
