@Jamie Bateman I agree that a listing-only alternative is likely insufficient. Zillow itself is diversified across multiple revenue streams (Zillow Premier Agent, Zillow Rentals, Zillow Home Loans, and data APIs). A competitor would have to take transaction fees (as Paperstac is doing today), but could also find revenue streams in aggregating and selling anonymized market data to institutional investors or researchers. Or offering personalized consulting, deal analysis, or portfolio review for an additional fee (as others are doing today).
Your comment makes me wonder if we have a "chicken and egg" problem in the note-investing market. We are assuming the market size is inherently small and fixed. However, the market's current size could be a result of limited accessibility, rather than limited interest or potential. Lack of user-friendly platforms to facilitate transactions could be artificially constraining the market. In many industries, the introduction of accessible platforms has led to market expansion by lowering barriers to entry. For example, stock trading became more widespread with the advent of online brokerages.
It might also be possible to attract new participants who were previously unaware of (or intimidated by) note investing. If you make transactions easier, there is potential to increase volume by providing better information and transparency, making the market more attractive.
It makes me wonder if we have a self-fulfilling prophecy here. The belief that the market is too small could be preventing investment in the very infrastructure that could help it grow. Your thoughts?
