However, I do know 2 investors who have purchased 70+ unit properties via seller outreach, but it takes time.

I would caution you with searching for lenders as those that don't follow a draw process or will lend on anything may not actually be a lender and trying to scam you.

I see people purchasing new STR's here and others dumping their properties or converting into LTR's. 

There are far too many regulations, the transaction is a much longer process, and we are talking about someone's biggest purchase.

If the tenant refuses to cooperate, begin the eviction process.

I was wondering if anyone knew how I can connect with or market to investors who specifically purchase land/ lots? 

I've purchased about 10 properties for myself and have always use my own broker.

These areas not only offer reasonable purchase prices for most investors but also feature turnkey homes—either newly built or fully renovated, ready for tenants, with systems that still have 10+ years of life remaining, and property management teams in place.

I also purchased the "training/coaching" and received very little support and what I did receive was not very valuable.

Purchase price: $150,000 Cash invested: $60,000 Rented it for $2195.
