Property Valuation and Comps Analysis

In real estate, accurate property valuation is the difference between profit and loss. Whether you're making an offer, justifying a listing price, negotiating repairs, securing financing, or analyzing investment returns—everything starts with one question: What is this property actually worth?

Enter the Deal Room Comps Tab: the most powerful collaborative property valuation tool ever built for real estate professionals and investors. It's not just a feature—it's a complete comparative market analysis platform that brings your entire team together to analyze, discuss, and agree on property values with unprecedented precision.

🎯 What Makes the Comps Tab Revolutionary

The Deal Room Comps Tab is the FIRST AND ONLY platform that allows unlimited team members to collaboratively analyze comparable properties in real-time, with shared notes, adjustments, and valuation discussions—all organized within your specific deal workspace. No competitor offers anything remotely similar.

What is the Deal Room Comps Tab?

The Comps Tab is a dedicated workspace within each Deal Room where your entire team can research, analyze, and discuss comparable properties (comps) to determine accurate market values. Think of it as a shared Comparative Market Analysis (CMA) workspace where investors, agents, appraisers, contractors, and lenders can all contribute their expertise to property valuation.

Unlike traditional CMAs created in isolation by a single agent or appraiser, the Deal Room Comps Tab enables collaborative valuation—where multiple professionals with different perspectives contribute to more accurate, well-rounded property assessments.

Core Features of the Comps Tab

Adjustment Categories:

3. Shared Comp Notes and Discussion

4. Automated Valuation Calculations

As team members add comps and adjustments, the system automatically calculates:

Real User Success Stories

Sarah K., Real Estate Investor (Portland, OR) - 7 Properties

"Before the Comps Tab, I was overpaying by 2-4% on every purchase because I didn't have the confidence to negotiate aggressively. I've used the Comps Tab on my last 3 purchases and saved an average of $14,300 per property. That's $42,900 in total savings in 8 months. The platform paid for itself 4,290 times over."

Robert M., Divorce Attorney (Chicago, IL)

"I've used the Comps Tab in 6 divorce cases for property valuation disputes. In every single case, we've reached settlement without going to trial—100% success rate. The transparency of the platform eliminates the 'he said, she said' battles over property values. This tool has saved my clients tens of thousands in litigation costs."

Amanda R., Listing Agent (Austin, TX) - 41 Transactions/Year

"The Comps Tab is my secret weapon in listing presentations. When I pull up the platform on my iPad and show sellers how I determine pricing with transparent data, I win 75% of listings on the spot. I've increased my listing volume 28% since implementing the Comps Tab, and my average days on market dropped from 34 to 21 days."
