I'm only building rental cabins which is a higher price point due to their ability to produce income. 

Vacation rentals in these mass-produced STR "neighborhoods" are really just a commodity, similar to a hotel room.

Trade school for plumbing is 2-4yrs, I'm not gonna take you from 0 knowledge to full comprehension on a web forum. 

As far as a reasonable fee, I'd say it has to do with the value brought, and product level produced.

Once you pick one give it a serious dedicated effort, but if it's producing no fruit after several months you can always pivot and shift. 

A marginal producer isn't likely to improve if you increase it's cost of finance.This is where you would sell and 1031. 

In 10 years it is virtual certainty that a leveraged purchase today would have produced a good return.

If you set them up as a "property manager" who was required to produce X amount of income to you (i.e. your rent amount) and then they'd get the rest. 

I’m ok planting some trees in todays environment and waiting a decade for it to produce.

Or just go to whatever brokerage affords you the most flexibility and just start networking with investors and investor agents to build that support system.As a part-time agent the last thing you want is high desk fees or other junk fees, since you may not be producing a ton in the beggining.
