What changes for commercial property
People buying or leasing offices, warehouses, and retail. LoopNet calls itself the world's number 1 3 commercial real estate marketplace, with 13 million 3 plus monthly visitors and 300K 3 plus companies searching.
They search by property type and bid on listings. LoopNet says it has been that brand for over 30 3 years.
What's the crossover
From ZillowFrom Zillow: a public listing graph you can search and map 5.
From commercial propertyFrom the market: offices, warehouses, and retail instead of houses 3.
A commercial Zillow already exists. A new app would need a narrower job, such as a property type or a country LoopNet does not cover 3.
Demand check
Publish a signup page for a property type in a metro and share it with brokers you can reach. Count signups against visits.
Build plan
- Start: list warehouses in a metro with size, docks, and a photo.
- Next: add a search by city and size.
- Then: add a lead form to the listing broker.
- After that: invite the signup list and watch whether brokers add another listing.
Copy the build prompt
Build a small web app for commercial property listings. Each listing has a type, a city, a size, and photos. A visitor can search and send a lead to the broker. Store listings, brokers and leads in a database. Use plain, accessible HTML.
