I think the buyers agency agreement is great for agents who produce, and the agents that do real estate as a side job will be a thing of the past. 

BiggerPockets type buyers are a tiny tiny minority who focus on day 1 cashflow.

I would definitely consider house hacking again but since we just bought out dream little piece of land to park our movable tiny house its definitely not my first thought. 

Your goal is to create an income producing portfolio so that you can retire from your blue collar job in 10 years.   

So they would be very hard to find them or have them work for you. expecting residential real estate agents to be experts at income producing properties is not realistic and not advised.. if your looking for investment property you should only be dealing with investment brokers .. there are designations for them or resi agents with the investment designation.. 

Looking for companies that would finance tiny homes.

Your goal is to create an income producing portfolio so that you can retire from your blue collar job in 10 years.

Looking to purchase an income producing ag property, farm and pasture land, that also has a massive gravel production site, over 20 acres of it (approximately 400,000 tons). 

Also will be adding tiny home cabins to property to make for cash flowing retreat/STR.

Over time, your RE will produce WAY more wealth than your 401k.
