What the Deal Builder does
This calculator needs JavaScript to run interactively. Here's a summary of what it covers.
Two starting points
Explore My Buying Power — start with your available cash and financial limits to see what purchase price those constraints may support, and what the property would need to earn.
Evaluate a Property — start with a listing or purchase price and see what the acquisition, operating and revenue assumptions produce.
What it asks for
Cash available, reserve to retain and maximum monthly contribution; purchase price, down payment, interest rate and loan term; a repairs/furnishing/launch budget; revenue as either annual gross accommodation revenue or ADR × occupancy; and management fee, platform fee and combined fixed annual operating costs.
What it returns
Opening cash required, the minimum modeled annual revenue needed to stay within your stated monthly contribution limit, planning-case monthly operating result, operating break-even revenue, and a conservative/planning/optimistic revenue stress test. These calculations reproduce the assumptions entered — they do not establish that the revenue, resale, permit or operating assumptions are achievable.
