Run it out. $180 x 0.60 x 365 is $39,420 gross. Take 22% management, that's $8,672. Platform fee around 3% of bookings, call it $1,100. Utilities, internet and trash on a beach condo, $250 a month, $3,000. Insurance uplift for nightly use over a landlord policy, budget $1,200 to $2,500 depending on state and carrier. Consumables and linen replacement, $1,500. Furniture and mattress replacement doesn't hit every year but it hits, so amortize $2,000. You're at roughly $22,000 to $23,000 before debt service, against $25,200 of mortgage, taxes and HOA.
That's assuming the 60% is real and evenly spread. In most beach markets it isn't. Sixty percent annual occupancy in a seasonal town usually means 85% for fourteen weeks and 25% for the rest, and the $180 ADR the agent quoted is often the peak season rate rather than the blended one. Ask for month by month booked nights and month by month realized ADR on the actual comps, not an annual average. The blended figure hides that you'll be writing checks from November through March and need six months of carrying costs sitting in reserve.
The other thing your numbers don't reflect: HOA insurance in coastal condo buildings has been repricing hard, and special assessments land on the owner regardless of what the unit earned. Pull the association's reserve study and last two budgets. If the master policy deductible is a percentage of value, find out what your share of a wind claim looks like.
