I never consulted with a lender, realtor, experienced investor... no one!

I mentioned the idea to my previous lender and he was saying about the same $100K-$150K.  

If you are financing the purchase, the lender will also provide protection, you will get an inspection done to protect you and so on.

If I understand your situation correctly, you could structure a Tenancy In Common (TIC) deal where each of the separate LLCs owns an undivided interest in the replacement property, as tenants in common.These deals need to be structured properly and you need to have an attorney familiar with 1031 exchanges involved to make sure it's done properly.Also, if there is a lender involved, that can complicate the matter as well.It's definitely doable, if you have the right professional help while you're doing it.Feel free to write if you have any questions about this.

Have been working with a lender the last few months.

There are lenders who will do vacant land.

Because you’re getting within 12 months of leaving the military, many lenders may want to see info on your next job for income.In addition to the VA loan, check out the NACA program at NACA.com.There are many lenders.

I meet some of my most influential connections at these meetups including fellow investors, mentors, lenders, contractors etc.

Might be best for syndication as the capital will be significant) Where do we find a private money lender / a hard money lender to start with?

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?
