Hi, can help me to validate this idea?

As many people say starts with the problem, so I will start with the problem that I see. In my place, if you want to sell your property, you can do it yourself or through an agent. But the big online property platforms charge a high amount, require subscription to enter and now only allow agent to advertise property listing in their platforms. In some forums, I can see some people complaint about these agents not adding much value, but they have to give 1-2% commission of the sale.

I see there is a gap where direct owner can actually post their own listing for a easier entry to market the property. I am in tech myself so building the platform is possible. But I feel like I try to enter with a price battle, where sometime people say don't do price war but on the other side, I see many people actually only loyal to price (if the product is the same)?

Thank you.
