I agree it does sometimes does give important additional information over what is listed in the “public” portals, it does not list the listing agent compensation, just the buyer agent compensation.

When I looked up who owns the properties on my county's tax portal, the county shows the owners' mailing address as the address of each respective property. 

I run my website and include the tenant portal provided by Rent Manager.

I didn’t see an agent portal anywhere on their website.

That is a huge hurdle for any company to have to overcome, and that is why with any national portal, the accuracy of their system is going to have issues.  

But check out Cozy.co - its a simple online payment/tenant portal site.

To accomplish this, GF had to position themselves as a RegA+ Tier II qualified funding portal under the JOBS Act which by law limits the amount they can raise to $50mil/year from non-accredited investors.Brian recently stated that as of now the company's only source of revenue is origination fees which range from 2 to 4%.

It’s advisable to list your FSBO or any other asset for sale in at least the top twenty classified ads portals.

So if you are looking for simple a portal that allows you to collect rent online, then Cozy gets the job done.

It is end to end property management portal, from application to rent payment!
