Marathon, FL · Investment
Does buying an Airbnb in Marathon make financial sense?
On modelled assumptions — a $505,000 purchase with $126,250 down — a Marathon short-term rental produces $57,052 of net operating income, a 11% cap rate and positive cash flow of $26,814 a year after financing. You need 36% occupancy just to cover the mortgage.

The full modelled pro forma
| Purchase price (modelled) | $505,000 |
|---|---|
| Down payment (25%) | $126,250 |
| Loan amount | $378,750 |
| Gross annual revenue | $83,900 |
| Operating costs (32%) | −$26,848 |
| Net operating income | $57,052 |
| Mortgage (30yr @ 7%) | −$30,238 |
| Cash flow before tax | $26,814 |
| Gross yield | 17% |
Operating costs are modelled at 32% of gross revenue for a nightly rental (cleaning, supplies, utilities, platform fees, maintenance, insurance) and 14% for a monthly rental. Financing assumes a 25% down payment and a 30-year loan at 7%. These are planning assumptions, not quotes — replace them with your own numbers. The purchase price shown is modelled from nightly-rate benchmarks, not from listing data — swap in a real asking price before you make any decision. Property taxes, insurance premiums and HOA dues vary enough between properties that they sit inside the 32% operating cost assumption rather than as separate line items.
What would break this deal
- Occupancy landing below 36% — the point where nightly income no longer covers the mortgage.
- A rule change that adds a minimum stay or caps nights. Check the Marathon rules before you buy.
- Paying peak-season prices for a property that only performs around Jan–Feb–Mar.
