The Seller-Finance Marketplace
Matching Buyers and Sellers Who Don't Need a Bank
Full Concept
With mortgage rates elevated and conventional financing friction at a decade high, seller financing has re-emerged as a viable path for many transactions. A marketplace to surface, structure, and close seller-financed deals with AI-assisted underwriting and document generation.
The Problem
Seller financing (where the property owner acts as the lender rather than a bank) has always been a viable path for real estate transactions that conventional financing can't serve. But the market for it is almost entirely informal: scattered listings, no standard discovery mechanism, complex deal structures that most buyers and sellers don't understand, and documentation that requires expensive legal help to produce correctly.
When mortgage rates rise and conventional financing becomes painful, the demand for alternatives spikes. But the infrastructure for those alternatives doesn't scale with demand.
The Platform
A dedicated marketplace for seller-financed transactions with three core components:
Discovery: Sellers who want to offer financing can list their properties with terms: interest rate, down payment requirement, amortization period, balloon payment schedule. Buyers can filter specifically for seller-financed deals by location, price, terms, and property type. This alone doesn't exist in any clean form today.
AI-Assisted Structuring: Most sellers don't know how to structure a seller-finance deal and most buyers don't know how to evaluate one. An AI layer walks both parties through the key variables (interest rate benchmarking, amortization modeling, balloon payment planning, risk assessment) and generates term sheets that both parties can understand before lawyers get involved.
Document Generation: Purchase agreements, promissory notes, deed of trust templates, amortization schedules, all generated automatically from the agreed terms. Not a replacement for legal review, but a way to arrive at that review with a complete and organized document set rather than a blank page.
The Market Timing
Elevated mortgage rates create structural demand for alternatives. Seller financing becomes more attractive to sellers (higher effective yield than most savings vehicles) and to buyers (access to properties that conventional underwriting won't touch). The platform that organizes this market during a high-rate environment builds the network effects that persist when rates eventually normalize.
The Longer Arc
This was one of the ideas that surfaced during my real estate period and connects directly to Purple Dog Listings. Both are attempts to give ordinary buyers and sellers the tools that previously required expensive intermediaries. The same thesis, applied to a different friction point in the same market.
