I have tried Zelle, Cash app, and Venmo but that seems very limited on functionality.

Only if world would function like this.

Those can be tinkered with and upgraded along the way, but in my experience most agents who enjoy the utility of their website will eventually move to a host service that adds a lot of bells and whistles onto the website (SEO, CRMs, blog posts, etc).I’d start with this:  many brokers have a master website with the ability for each agent to have a micro-site within it (could be an agent page, possibly some search functionality, etc).  

This will help people connect with you after determining how their goals, services and resources align with yours.2. use the 'search' function to find topics, members and areas of interest.

Maximized potential by creating an additional unit that was originally just a "mother-in-law suite" and properly separated units to function as two independent STRs.

We have sellers and potential tenants that do not fill out things properly and we need different ways to search what they might be talking about and now we do not have that functionality. 

You essentially lower your exit cap by improving the park from a visual and functional stand point. 

@Sodasia Thompson you need to be careful in Binghamton due to the “functional family” law.

Do you use something else that provides similar functionality?

Make it functional, clean, and go for it again.
