How much does it cost to build custom accounting/property management software using AI-assisted development versus traditional development?

Building this without AI was estimated at $500,000–$750,000 or more in spend. Using AI-assisted development, the actual spend has been about $50,000 on the engineering side (not counting the founder's own time). The team consists of five people: three main engineers plus two others brought in as needed, all working as independent consultants. A key advantage noted is that because the cost to develop with AI is so low, the cost to throw work away and start over is also low, which helps avoid the tech debt that comes from being locked into early architecture decisions.
