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?

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.

I know Shopify typically is a more commerce base platform.

I'd stay on platform.

Hi, I just started using BiggerPockets and am excited to learn about the community and all the resources available. I'm particularly excited to find others in my area and start to attend some meetup groups!

I continue to see new platforms promise ease of use, lightning-fast approvals, and streamlined processes.

When you have employees promoting the platform like it is the best platform ever and free accounting services, it was going to go down sooner or later.Pretty sure their other services are going to go down shortly.Baselane is offering assistance I believe, but they are just like Azibo.

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.
