The Best Alternatives to Privy or PropStream for Comps

The best alternatives to Privy or PropStream for comps are platforms that pull comparable sales fast, calculate repair costs, and hand investors a confident offer number before the seller even hangs up the phone. For years, Privy and PropStream have been the go-to choice for pulling comps, but both still require manual review, spreadsheet adjustments, and a fair amount of gut-feel judgment. As a result, many wholesalers and investors now turn to AI-powered comp analysis software that compresses that 20-to-30-minute process into about a minute. In this guide, we compare the leading options — including ChatARV — and explain how to pick the right fit for wholesale, fix-and-flip, novation, or buy-and-hold deals.

What Are the Best Alternatives to Privy or PropStream for Comps?

In short, the best alternatives to Privy or PropStream for comps include ChatARV, REsimpli, Rehab Valuator, and DealMachine, each pulling comparable sales ("comps") and estimating property value with a different mix of speed, data coverage, and investor-specific features. Specifically, AI-first tools like ChatARV focus on getting a wholesaler to an offer number fast, while PropStream and Privy lean on broad nationwide data that still needs manual interpretation.

Comparable sales, or comps, are recently sold properties similar in size, condition, and location to the subject property. Appraisers and investors use them to estimate what a home is worth today, as well as what it could be worth after repairs, which is where the After Repair Value (ARV) calculation comes in. According to the Wikipedia entry on real estate appraisal, the comparable sales approach remains one of the three primary valuation methods used across the industry.

Therefore, the "best" alternative really depends on your workflow. If you need a defensible number while a seller is still on the phone, an AI comp tool wins. If you need raw skip-tracing and marketing lists alongside comps, a data-heavy platform might still earn a place in your stack.

Why Investors Look Beyond Privy and PropStream

PropStream pulls from a wide database of public records and listing information, and Privy layers MLS comps on top of agent-focused tools. However, both still ask the investor to filter, weigh, and adjust comps manually. In practice, that means 20 to 30 minutes of clicking through listings, cross-checking square footage, and second-guessing condition adjustments before you even start the offer math.

In wholesaling, speed is money. The investor who gives the seller a confident number first is usually the one who gets the signed contract. Consequently, pulling the wrong comps — or taking too long to pull the right ones — either kills your margin through overpaying or costs you the deal through a lowball guess.

In addition, consistency is a real problem with manual comping. Two different analysts pulling comps for the same property can land on two different ARVs simply because they weighted proximity or condition differently. For example, our guide on how AI comping compares to manual comping breaks down exactly where that inconsistency creeps in.

Above all, non-disclosure states compound the problem. In states where sale prices aren't public record, investors without Multiple Listing Service (MLS) access have historically been forced to guess at values. That gap is exactly why several newer platforms were built in the first place.

Top Comp Analysis Tools for Wholesalers and Investors

Below is a closer look at the tools investors most commonly compare against Privy and PropStream when searching for a faster or more specialized way to run comps.

ChatARV: AI-Powered Comps and Offers in About 60 Seconds

ChatARV is an AI deal-analysis platform purpose-built for wholesalers and investors rather than agents. Type in any property address and, in roughly a minute, it surfaces the top six comparable properties, weighing proximity, recency, and condition, then automatically adjusts for square footage, bedroom and bathroom count, and lot size. As a result, you get the ARV range, the as-is value, an estimated repair cost, and a ready-to-use offer across every exit strategy — wholesale, novation, fix-and-flip, buy-and-hold, and BRRRR (Buy, Rehab, Rent, Refinance, Repeat).

Notably, ChatARV supports all 12 non-disclosure states, pulling MLS-sourced transaction data across a wide set of providers so you don't need your own MLS access to run accurate comps. For a deeper walkthrough, see this breakdown of how to run comps without MLS access.

Deals change after the walkthrough, so investors can update the repair scope and ChatARV recalculates the entire report instantly. More than 20,000 active users across the U.S. currently rely on the platform, and reports can be shared directly with sellers, cash buyers, or dropped into existing underwriting sheets, including the as-is comp reports format many buyers already expect.

PropStream: Broad Nationwide Data, Manual Analysis

PropStream remains popular for its lead generation, skip-tracing, and nationwide property records. However, its comp function still leans on the user to select, filter, and manually adjust each comparable. In contrast to an automated report, PropStream gives you the raw data but leaves the valuation judgment largely in your hands.

Privy: MLS-Based Comps for Agents and Investors

Privy pulls comps directly from MLS feeds and is well regarded for mapping and market-trend visuals. That said, it was originally built with real estate agents in mind, so wholesale-specific outputs like MAO (Maximum Allowable Offer) or BRRRR cash-flow projections aren't native to the platform. Similarly, Privy's coverage depends on MLS partnerships, which can be thinner in some non-disclosure markets.

Other Notable Comp Tools: REsimpli, Rehab Valuator, and DealMachine

REsimpli bundles CRM and marketing features with basic comping. Rehab Valuator focuses heavily on flip and rehab budgeting math. DealMachine is primarily a driving-for-dollars and skip-tracing tool with comps as a secondary feature. For investors whose core bottleneck is speed-to-offer rather than marketing, these tools are typically a supplement rather than a direct replacement.

PropStream Alternative Comparison: Side-by-Side

For a quick reference, here's how the main options stack up on the factors wholesalers and investors care about most.

How to Choose the Right Comping Software for Your Exit Strategy

First, think about which exit strategy you run most often. A wholesaler needs a fast MAO; a buy-and-hold investor needs cash-flow projections; a flipper needs an accurate repair budget against ARV. In particular, a generic data tool forces you to do that math yourself every time, while a purpose-built comp analysis platform builds it into the report automatically.

Second, check coverage in the states where you actually buy. If you operate in a non-disclosure state, confirm the tool can source transaction data there before you commit. Our non-disclosure state investing guide outlines which 12 states fall into this category and what that means for comping.

Finally, consider defensibility. A comp report that only shows a number isn't as useful as one that shows the comps used and every adjustment applied, because you'll need to justify that figure to sellers, buyers, and partners. According to the National Association of Realtors, millions of residential transactions close in the U.S. each year, and consistent, repeatable comps are what separate a confident offer from a guess across all of them.

Step-by-Step: Running Comps With an AI Alternative

Here is the general process most AI comping platforms, including ChatARV, follow when turning an address into an offer.

1. Enter the property address. Type the full address into the platform so the AI can pull nearby sold properties and current listing data for that specific block or subdivision.
2. Review the AI-selected comps. The tool surfaces its top matches, typically six properties, weighted by proximity, recency of sale, and overall condition relative to the subject property.
3. Adjust for condition and repair scope. Swap comps, toggle them on or off, or add your own, then update the estimated repair cost to reflect what you actually saw during the walkthrough.
4. Generate the exit-strategy breakdown. The platform calculates ARV, as-is value, and offer numbers for wholesale MAO, flip profit, buy-and-hold cash flow, and BRRRR projections simultaneously.
5. Share the finished report. Export the comp report to send to the seller, a cash buyer, or your own underwriting team, keeping every adjustment documented for later reference.

Frequently Asked Questions

What are the best alternatives to Privy or PropStream for comps?

The best alternatives to Privy or PropStream for comps are AI-driven platforms like ChatARV, along with niche tools such as REsimpli and Rehab Valuator. Each pulls comparable sales and generates a value estimate, but they differ in speed, data coverage, and built-in offer calculations.

How does ChatARV calculate ARV differently than PropStream?

ChatARV automatically selects and weights the top six comps, then adjusts for square footage, bed/bath count, lot size, and condition without manual input. PropStream, in contrast, provides the comp data but leaves selection and adjustment to the user.

Can I run comps in non-disclosure states without MLS access?

Yes. ChatARV pulls MLS-sourced transaction data across multiple providers and supports all 12 non-disclosure states, so you don't need personal MLS access to generate accurate comps there.

Why do wholesalers need faster comp tools than traditional MLS searches?

Because speed is money in wholesaling. The investor who gives a confident, defensible offer first usually wins the contract, and manual MLS searches typically take 20 to 30 minutes per property.

How much does a PropStream alternative typically cost?

Pricing varies widely by platform and depends on report volume, user seats, and whether data add-ons like skip tracing are included. Most tools offer monthly or per-report plans, so it's best to confirm current pricing directly on each provider's website.

How long does it take to generate a comp report with an AI alternative?

With a platform like ChatARV, a full report including ARV, as-is value, and an offer across exit strategies takes roughly 60 seconds. Traditional manual comping, by comparison, often takes 20 to 30 minutes per property.

What common mistakes do investors make when pulling comps manually?

The most common mistakes are selecting comps that are too far away or too old, and failing to adjust consistently for condition differences. These inconsistencies lead to overpaying and losing margin, or underbidding and losing the deal.

Is Privy better than PropStream for comps?

Neither is clearly better; they serve different needs. Privy leans on MLS data with strong mapping visuals, while PropStream offers broader public-record coverage plus lead generation, but both still require manual comp analysis.

What's the best practice for adjusting comps for repair condition?

Best practice is to update the repair scope the moment it changes, such as right after a walkthrough, and let the tool recalculate the full report instantly. This keeps the ARV and offer numbers aligned with reality instead of an outdated estimate.

Can I use ChatARV for buy-and-hold and BRRRR deals, not just wholesaling?

Yes. ChatARV generates a full exit-strategy breakdown for every report, including buy-and-hold cash flow and BRRRR projections, in addition to wholesale MAO and flip profit.

Do I need my own MLS access to use an AI comping tool?

No. Platforms like ChatARV source MLS-based transaction data through their own provider network, so individual investors don't need a personal MLS login to pull accurate comps.

What makes a comp report defensible to sellers and buyers?

A defensible report shows the ARV range, the specific comps used, and every adjustment applied rather than just a final number. That transparency lets you explain exactly why the offer is what it is, to sellers, buyers, and partners alike.

In summary, the best alternatives to Privy or PropStream for comps come down to how much manual work you're willing to do between pulling data and making an offer. Privy and PropStream remain capable data sources, but AI-first platforms like ChatARV's deal-analysis platform compress comping, ARV, and exit-strategy math into roughly a minute, so investors can give sellers a real number on the same call. Ultimately, the right choice depends on your workflow, your target states, and how fast you need to move to win the next deal.
