Quote from @Chris Lo: Which platforms/websites do landlords use to find the rent rate, how long the rental properties have been on the market, and all the details about other rental properties?

Listing on multiple platforms does affect ranking by platforms but not as much as you think.  

What if something changes with how that platform works?

If I was approaching this I'd want chatbot that used the ChatGPT language model but was closed off from the internet and only trained on my data.

These platforms include RentRedi, Stessa, Avail, Innago, Apartments.com (formerly Cozy), and TenantCloud.Pretty much every platform mentioned contains the features you are going to need.

Has anyone bought from the platform?

I know Shopify typically is a more commerce base platform.

Paid platforms often offer additional features like market analytics, off-market property leads, and filters for investor-specific criteria, giving them a leg up over free options.Exactly, most platforms have to offset cost somewhere because of how expensive it is to keep the data up to date.

Please check out our Product Tours on the dashboard for an overview of the platform.

I will try and remember to come back and update what I find out in a week or two of testing out both platforms.
