They ask about staying long term, hoping the thought of all that money will entice you to interact with them and leave your defenses down. 

Again, the BiggerPockets store has some books on this topic, or you can learn about it by watching podcasts, reading blogs, and interacting on the forum.

All of you interactions should be viewed through that lens.

This is a lot of land so also keep in mind the logistics of how guests will arrive to their respective sites, parking, guest interaction, etc.

The first interactions are critical,  every inch you give, you will never get back.

You can also directly use the BP Marketplace to find potential JV partners or buyers, which is a great way to connect with people who are already looking for investment opportunities.In addition to online forums, attending local real estate meetups and conferences can give you face-to-face interaction with potential partners or buyers, which often builds stronger relationships.

But we have a lot of interaction with guests before they ever arrive - we require a photo ID of whomever has booked our house (and the name and info has to match the booking info), a working cell phone number that we will send a test message to by text to confirm it belongs to the guest (or is at least in their possession), and we converse with them to let them know what to expect from us (and if we have any specific concerns we share those as well) - for example, this week if we had anyone scheduled to arrive we would be discussing the incoming hurricane. 

Here are some areas where automation and tech adoption can make a difference: Customer Relationship Management (CRM): Use a robust CRM system to track interactions with potential buyers, sellers, tenants, and partners.
