Tweet hook

Airbnb arbitrage: lease an apartment, sublet on Airbnb, pocket the spread.

Most "deals" don't pencil out once you bake in turnover, fees, vacancy.

Built a calculator that flags optimistic-occupancy assumptions and long break-even periods. Brutally honest math 🧵

Subject: optimistic occupancy assumptions

Hi {first} — saw your STR portfolio post.

Most calculators online assume 75-80% occupancy. AirDNA averages run
55-65% in Year 1. The difference is whether you're profitable.

Built a calculator that flags optimistic assumptions, computes
break-even months, and surfaces deals that ACTUALLY pencil. Free
to try.

DIY $0; alerts subscription $99/mo per metro.

ROI math

gross  = rate * 30.4 * occupancy
net    = gross
       - rent
       - cleaning_turns * cleaning_per_turn
       - utilities + supplies
       - airbnb_host_fee% * gross
       - mgmt_fee% * gross
roi    = (net * 12) / setup_cost
