Best Real Estate Comp Analysis Software in 2026
Comparable sales analysis is the foundation of every real estate investment decision. Whether you are estimating the after-repair value (ARV) for a flip, setting a rental rate, or pricing a wholesale assignment, accurate comps determine whether you make money or lose it. The right comp software saves hours of manual research and reduces the risk of relying on flawed data.
We evaluated six approaches to comp analysis in 2026, from dedicated investor platforms to free tools and MLS access. Each has different strengths depending on your strategy, market, and budget.
What makes good comp software
Before comparing tools, here is what to evaluate in any comp analysis platform:
- Data freshness: How current are the sold comparables? Stale data from six-plus months ago may not reflect today's market. Recent sales within the last three to six months are most reliable.
- Filtering capabilities: Can you filter comps by distance, square footage, property type, condition, and date? The more granular the filtering, the more accurate your ARV estimate.
- Map visualization: Can you see comps on a map relative to the subject property? Location context matters — a comp across a highway or in a different school district may not be comparable despite being nearby.
- Condition adjustment: Does the software account for property condition differences? A renovated comp selling for $300,000 is not directly comparable to a property needing $50,000 in repairs.
- Active and pending data: Can you see what is currently listed and under contract? Active listings set the ceiling for your ARV; pending sales confirm market activity.
- Price per square foot: Does the tool calculate and display price per square foot for easy comparison across different-sized properties?
The best comp analysis tools reviewed
1. Deal Run — Best AI-powered comp analysis for investors
Price: Starting at $99/month
Deal Run's comp analysis tool is built specifically for real estate investors who need to estimate both sale value (ARV) and rental value (ARR). The platform pulls recent sold, active, and pending comparables and displays them on an interactive map alongside a data grid.
What sets Deal Run apart is the AI-powered comp scoring. Each comparable is scored based on multiple factors including proximity, size similarity, condition alignment, and recency. This helps you quickly identify which comps are most relevant to your subject property instead of manually sorting through dozens of results. You can filter by distance radius, square footage range, property type, and sale date.
The dual ARV/ARR analysis is particularly valuable for investors who evaluate properties for both flip and rental potential. The rental comp analysis follows the same methodology, pulling recent lease comparables and estimating achievable rent.
Pros:
- AI scoring ranks comps by relevance automatically
- Both ARV (sale) and ARR (rental) comp analysis
- Interactive map with filtering controls
- Integrates with repair estimation and MAO calculator
- Active, pending, and sold comp data in one view
Cons:
- Newer platform — less brand recognition than established tools
- Best suited for residential properties (1-4 units)
Best for: Investors who need accurate, AI-assisted comp analysis integrated with deal analysis and disposition tools.
2. PropStream — Best for quick comps alongside property data
Price: $99/month
PropStream includes a comp analysis tool within its property data platform. Search any address and pull recent sold comparables in the surrounding area. The comp display shows sale price, square footage, lot size, and price per square foot. You can adjust the search radius and date range.
PropStream's comp tool is functional but basic. It shows you the data without much analysis or scoring. You are responsible for evaluating which comps are most relevant and making condition adjustments mentally. The real value of PropStream is the property data platform around the comps — you can identify a motivated seller, pull comps, and export the list for outreach all in one session.
Pros:
- Comps integrated with nationwide property data platform
- Quick access alongside distress filters and owner data
- Adjustable search radius and date filters
- Familiar interface for PropStream users
Cons:
- No comp scoring or condition adjustments
- Basic display — no AI or smart filtering
- No rental comp analysis
- Map view is functional but not interactive in the same way as dedicated tools
Best for: PropStream users who want basic comp analysis within the platform they already use for data and list building.
3. HouseCanary — Best institutional-grade AVM
Price: Custom enterprise pricing
HouseCanary provides automated valuation models (AVMs) and property analytics used by institutional investors, hedge funds, and lenders. Their AVM incorporates machine learning across millions of transactions and claims median accuracy within a few percentage points of actual sale prices. The platform also provides market forecasts, risk assessments, and portfolio analytics.
For individual investors, HouseCanary is typically out of reach due to enterprise pricing. But if you have access through a brokerage, lender, or investment fund, the data quality is among the best available. The AVM should still be cross-referenced with manual comp analysis — no automated model accounts for unique property conditions.
Pros:
- Best-in-class automated valuation models
- Market forecasting and risk scoring
- Institutional-grade data quality
- API available for integration into custom workflows
Cons:
- Enterprise pricing — not accessible for individual investors
- AVM cannot account for individual property condition
- No built-in deal analysis, disposition, or investor tools
- Designed for portfolio-level analysis, not single-deal evaluation
Best for: Institutional investors and funds that need portfolio-level valuation analytics.
4. CompStak — Best for commercial property comps
Price: Free for contributing members / paid for enterprise
CompStak is a crowdsourced database of commercial real estate lease and sale comparables. Real estate professionals contribute comp data from their own deals in exchange for access to others' data. The result is a database of verified commercial comps that is difficult to find elsewhere.
For residential investors, CompStak is not relevant. But for commercial investors, especially in multifamily, office, and retail, it fills a critical gap. Commercial sale prices and lease terms are notoriously opaque — CompStak's exchange model surfaces data that never appears in public records.
Pros:
- Best source of commercial lease and sale comps
- Crowdsourced from verified real estate professionals
- Data not available through other platforms
- Free access if you contribute your own comp data
Cons:
- Commercial only — no residential data
- Requires contribution to access (or enterprise subscription)
- Coverage varies by market
- No analysis tools — raw comp data only
Best for: Commercial real estate investors who need verified lease and sale comparables.
5. Redfin — Best free comp research
Price: Free
Redfin provides free access to MLS listing data including recent sold prices, listing history, and property details. For investors on a budget, Redfin is the best free source of comp data. You can search sold properties by area, filter by date and price range, and view results on a map.
The limitation is that Redfin is designed for homebuyers, not investors. There are no investor-specific filters, no batch analysis tools, and no integration with deal calculators. You are doing manual comp analysis — pulling up each comparable individually and making mental adjustments. For a single deal, this is fine. For volume, it does not scale.
Pros:
- Completely free
- Generally accurate MLS sold data
- Good map-based search for comps by area
- Redfin Estimate can serve as a cross-reference point
Cons:
- No investor-specific tools or filters
- Manual process — does not scale for volume
- No condition scoring or AI adjustments
- Cannot export comp data for use in other tools
Best for: Beginners and budget-conscious investors who need basic comp data for occasional analysis.
6. MLS Access (via agent or license) — Best raw data source
Price: Varies (MLS dues typically $30-$100/month through a brokerage)
Direct MLS access provides the most current and comprehensive comp data available. Active listings, pending sales, sold data, price changes, days on market, listing agent remarks, and full photo sets. If you have a real estate license or a relationship with an agent who provides MLS access, this is the gold standard for comp research.
The downside of raw MLS access is that it is designed for agents, not investors. The interfaces are often clunky, there are no deal calculators or ARV estimation tools, and you need to know how to search and filter effectively. Many investors get an agent license specifically for MLS access, or they partner with an investor-friendly agent.
Pros:
- Most current and comprehensive comp data available
- Active, pending, withdrawn, and sold data
- Agent remarks with condition details and seller motivation clues
- Full photo sets for every listing
Cons:
- Requires a real estate license or agent partnership
- Interfaces designed for agents, not investors
- No deal analysis or ARV estimation tools
- No disposition, buyer search, or marketing features
Best for: Licensed investors or those with agent partners who want the most comprehensive comp data available. For a deeper dive, see our guide on how to use MLS data for comp analysis.

Common comp analysis mistakes to avoid
Regardless of which tool you use, avoid these frequent errors:
- Using comps from too far away. A comparable sale two miles away in a different neighborhood is not comparable. Stick to the immediate area — half a mile or less in urban markets, one mile in suburban.
- Ignoring condition differences. A fully renovated comp that sold for $280,000 does not mean your fixer-upper is worth $280,000 after repairs. Account for the condition gap and adjust accordingly.
- Using comps that are too old. In a rapidly changing market, a sale from twelve months ago may not reflect current values. Prioritize sales from the last three to six months.
- Cherry-picking high comps. It is tempting to use the three highest comps to justify a higher ARV. Resist this. Include comparable sales that challenge your thesis, not just those that confirm it.
- Ignoring active listings. Active listings set the ceiling for your ARV. If no renovated comparable is currently listed above $250,000, your ARV is probably not $280,000 regardless of what sold six months ago.
