REI Prime - Rental Property Analyzer

About

Analyze rental properties instantly — right on the listing page.

REI Prime is the deal analyzer for real estate investors. Browse any property on Zillow, Redfin, or Realtor.com and see the investment numbers that matter — cash flow, cap rate, cash-on-cash return, and ROI — without leaving the page or opening a spreadsheet.


★ WHAT YOU GET

✓ Instant deal metrics — cash flow, cap rate, cash-on-cash return, ROI, DSCR, NOI, gross yield, and 1% rule calculated in real time
✓ Automatic data extraction — price, rent estimates, taxes, insurance, beds, baths, and sqft pulled directly from the listing
✓ AI-powered estimates — missing rent, taxes, or insurance? One click fills the gaps using market data
✓ Color-coded deal signals — green, amber, and red indicators show deal quality at a glance
✓ Adjustable assumptions — set your down payment, interest rate, vacancy rate, and management fees once — they save automatically and carry over to every property
✓ Cash flow breakdown — see every income and expense line item, monthly and annual
✓ First-year return analysis — cash flow + principal paydown + appreciation = total return
✓ Shareable analysis — copy a pre-filled calculator link to send to partners, lenders, or your team
✓ Full analysis — one click opens the complete REI Prime calculator on reiprime.com with all your data


★ HOW IT WORKS

1. Navigate to any property listing on Zillow, Redfin, or Realtor.com
2. Click the REI Prime icon to open the analysis side panel
3. See your deal metrics instantly — adjust assumptions and watch the numbers update in real time
4. Share the analysis or open the full calculator for a deeper dive


★ YOUR ASSUMPTIONS, YOUR WAY

Every investor has different criteria. Set your down payment percentage, interest rate, loan term, vacancy rate, property management fee, maintenance reserve, and closing costs once. REI Prime saves your assumptions and applies them to every property you analyze — no re-entering the same numbers on every listing.

When you change a property, your assumptions carry over. When you want to start fresh, one click resets to defaults.


★ SUPPORTED SITES

★ WHAT MAKES REI PRIME DIFFERENT

Most deal analyzers require you to manually enter every number into a spreadsheet or app. REI Prime reads the data directly from the listing page — price, rent, taxes, insurance, and property details are extracted automatically. You spend less time on data entry and more time evaluating deals.

When data is missing (common for taxes and insurance), REI Prime's AI fills the gaps with one click — powered by real market data, not generic estimates.


★ PRIVACY

We respect your data:
— No personal information collected
— No browsing history tracked
— No property addresses stored on our servers
— AI estimates send only basic listing details — nothing is stored after the response
— Anonymous usage analytics only (no PII, prices bucketed into ranges)
