As was stated previously I think the main thing is making it clear to the owner that you are an agent and what your intentions are, and making sure the paperwork you and the owner sign clearly defines that.

You can definately make it work using the BRRRR strategy!

When I see such vastly different types of markets on someone's list, it usually indicates to me that they haven't clearly defined their objectives and criteria.

If you define the purpose of the land that should help with selling it.

Seems like documentation (timelogs, etc) is very important in case of audit, as well as meeting the IRS-defined qualifiers (material participation of 750+ hours and over 50% of work done in real estate). 

Definately deals on there but they are tough to get unless you have some sort of competitive advantage and can buy tighter than the rest, and really hard to wholesale for many reasons. 

We specialize in investors clients and I am personally very committed to understanding market trends, both housing and economic more broadly.

It's a broad topic that experienced investors in this area could write a book on. 

@Jonathan Pavkov Define "A Neighborhood"...based on what?

The tenants can definately vouch that they never heard or asked for cash for keys from seller&realtor during the phone meeting they had.
