nnamusoboko/market-research-agent ? reverse-engineered prompt

Build me a Python service for real estate market research that can take a property ID and user ID, look up the property in MongoDB, find current rental comps for the area, and generate a clear recommendation saying whether the rent is fair, below market, or above market.

I want it to save the result back onto the property record so my app can show the status, the estimated market rent, and a short markdown summary right away. It should use an API key header for my app to call it, and it should only allow research for properties that belong to the user sent in the request. If the market price is way off from the listed rent, it should flag it for human review before marking it ready.

Please make it run as a simple HTTP service with a basic API endpoint, support async processing, and include a background job that refreshes stale properties every week. If you need current library details or API docs, look them up online and use sensible defaults.
