Personally I have not had the best experiences with these sites, I typically go via word of mouth referrals from other investors I know from in-person networking in my market, or from the BiggerPockets referral tools.

There's a ton of meetups if you search for them here on the site.

Hey @W Lee welcome to the site!

When adding a single ADU, the cost of adding the ADU hands off is typically greater than the value added if in single family zoned areas.Here is a list of why a hands off ADU addition costs s often one of the worse investments.  

Most users may not visit a 3rd party site, and you could collect some answers by asking for genuine feedback here on the forums.

However, this approach might add complexity, such as additional tax filings, self-employment taxes, and administrative costs.

Unfortunately the additional fee disproportionately impacts smaller projects (I recently paid the same acceleration fee for  $600,000 SF renovation as I just did for a $2.5M school building conversion). 

It is the intention to live there, but if something comes up i.e. neighborhood troubles, job placement, additional family member, etc. then there isn't an issue. 

then MLS feeds to all the SM sites and agents can filter through the responses or if it my own property like here in Oregon with our subdivisions I handle the first calls and then qualify them once done and appointment set hand it off to the closer ( my wife )  If I get a ton of E mail request for info I just tell them they need to come and look first.

(These averages represent state-level data, and individual cities may levy additional taxes.)To achieve the same level of cash flow as a property in Nevada, you would need to generate a higher cash flow in Texas to offset the higher operating costs.
