FAQ

Is PropertyCost free?

Calculators are free (no signup needed). You also get 1 Full Analysis output free. After that, advanced features use credits only when you run them.

What is “Full Analysis”?

It is an informational software output: good / caution / avoid + key reasons and the next run to improve the deal (price, rent, vacancy, expenses, horizon, etc.).

How is the output generated?

The informational software output is generated from your inputs and platform logic (cash flow, real returns, taxes/fees, inflation impact, stress checks). You can inspect what drives each result.

What are scenarios?

Scenarios are a fast stress test. They automatically try realistic changes to controllable inputs and show which ones actually move the outcome.

What is “Deep dive”?

A focused breakdown of one scenario: what changed, how it affected key metrics, and the trade-offs to watch.

What is “Ask In-App AI Analyst”?

Ask questions about your deal in context (e.g., “What if vacancy is 12%?” or “Which input matters most?”) and get a software-generated informational answer tied to your saved output.

Can I compare deals or summarize my portfolio?

Yes. Compare two deals of the same type to pick a winner, and run a portfolio summary to see strengths, weaknesses, and next actions across multiple deals.

Can I export a report?

Yes — export a clean PDF report to share or archive.

Is this financial advice?

No. It’s informational and depends on your inputs. Always verify assumptions and consult professionals when needed.
