Seller Challenges We're Built For

The Problem

Scaling inefficiencies

Manual processes and tooling sprawl slow execution and waste time.

Workload bottlenecks

Running multiple deals at once becomes difficult without a repeatable system.

Missed opportunities

Relationship-dependent deal flow and inconsistent execution can limit outcomes.

Our Solution

Maximize liquidity and price discovery

Reach more qualified buyers through a guided, repeatable exposure.

Reduce operational burden

Guided workflows replace ad-hoc processes.

Close with audit-ready execution

Consistent documentation and compliance at every stage.

Sell Individual Loans

Auction performing, non-performing, or re-performing notes and execute through a guided, repeatable transaction flow.

Run Portfolio Auctions

Structure competitive bidding for pools of loans with controlled buyer participation and coordinated diligence.

Inventory Liquidation & Dispositions

Offload aged or underutilized assets through managed sale processes with configurable access and participation rules.

Forward-Flow Programs

Establish recurring sale pipelines with pre-qualified buyers, consistent terms, and repeatable execution frameworks.

Supports larger, more strategic trades and repeat execution.

Pricing Intelligence

Paperstac Price Predictor (PPP)

Sanity-check pricing and assess bid competitiveness using historical Paperstac transaction data.

PPP uses historical Paperstac sale data and Paperstac AI to estimate a fair-value price range for loans being listed or evaluated — similar to how Zestimate works for residential real estate, but purpose-built for the secondary mortgage market. As bids come in and the auction end approaches, that range updates to reflect real-time market demand and competitive pressure.

Both buyers and sellers benefit. For sellers, PPP provides a data-informed starting point for pricing and a live signal as the auction progresses. For buyers, it offers a current reference range to evaluate whether a deal is priced competitively relative to comparable transactions and active bidding behavior on the platform.

Estimate only; not an appraisal or guarantee.
