I have asked if someone is teaching this offer structure and one person said it's common in land and the other explained it as a win-win situation. 

However, the person who knows how to effectively use AI tools like ChatGPT to get more done will replace you.

I only use it for my personal stuff, and exclude anything that has to do with my rentals, which I'm assuming would be the plan for yourself.

Do not just get randoms, this is going to take a lot of work to protect your privacy and personal residence.

It sounds like you personally are focused on an urban infill strategy which maximizes density and price per square foot rent.

I found myself attending in-person networking almost weekly prior to the pandemic, but we live in a different world, and the digital shift has made it harder.Currently looking for personal investment deals in the area, and also passionate about connecting other local investors with trusted service providers.

I would love to meet up with investors and agents in person in my area to learn more about real estate and any advice they may have.

So personal preference and your goals. 

I find TPs rent control too restrictive personally.

The HELOC would need to go off your personal situation but if needed you may be able to do DSCR on the short term rental.
