Q1
You can still install the extension and use the browser workflow, but an account is required to access the dashboard and saved history features.
FAQ
Frequently Asked Questions
Q2
No. The current scope is supported Zillow, Redfin, and residential LoopNet pages. The workflow is strongest where the extension can reliably parse listing context.
Q3
The extension helps in the moment. The dashboard provides a second life so you can review signals after the tab closes or after you’ve saved several properties in a row.
Q4
Yes. While the extension is free to use, we plan to introduce paid plans around saved analyses, compare workflows, and longer-term account value.
Q5
That usually means that no properties have been saved to your account. The extension hasn’t yet imported a compatible listing into your current signed-in account context. Try browsing a supported page again and select 'Save to Dashboard', then reload the dashboard.
Q6
PropComp uses a residential rental underwriting model based on imported property details and the user assumptions saved with each property. The six dashboard metrics are calculated as:
NOI

GRM
=Purchase PriceAnnual Gross Rent
Cash Flow
=NOI−Monthly Mortgage Payment
Cap Rate
=Annual NOIPurchase Price×100
CoC
=Annual Cash FlowCash Invested×100
DSCR
=NOIMonthly Mortgage Payment
Supporting inputs include vacancy loss, management, repairs, CapEx, insurance, property tax, HOA, and other monthly costs inside operating expenses.
Cash invested is calculated as down payment plus closing costs.
