Is there a general rule of thumb for translating that revenue into a sales price? 

There’s no real way to create phantom losses without running into issues with the IRS, and you could end up losing important tax benefits.

So you have to create that balance for yourself.I don't think your goals are bad, you are basically living below your means (in an RV) and buying rental properties.

Now this does create a chain of liability where you (the employer) is liable for any misdeeds by the non-licensed employee be it by intent or ignorance, it will not matter. 

As a result, I actually created my own frankenstein of an automation pipeline combining public notices, county data and skip tracing so I can get the leads directly from the source and act on them as soon as they are available. 

They've gone as far as writing algorithms that pull data points like crime rates, age, median income, number of coffee shops and hundreds of others to create heat maps of where to buy.  

I am looking into creating business entity and place all property under that.

They have bots that look for every piece of furniture on the internet, create a listing for it, and then have it shipped if you buy it (often at a 2-3X markup). 

These include drafting offering documents, adhering to ongoing disclosure rules, and audits, which can easily run tens or hundreds of thousands of dollars.

Although, I am an advocate of documenting and creating systems, in the first few years all of your systems are going to change many times and so are everyone's roles within the company.
