Federal laws are pretty much tied together, like an overlay, there can be matters that fall under SEC, the Tax Code, the FTC, Treasury Department, FDIC, I think someone listed over 60 related laws and regulation that apply to lending activities, it's a vast financial world.

For a true comparison, an appropriate fair market value for your labor in this regard must be subtracted from the income or interest earned.As an example, let's say the riskless 10 year treasury bond yields 3%.  

There other value is to indicate where values are headed.There is something called a risk premium, the spread between the cap rate and 10 yr treasury.  

Unless of course you are trying to play the speculative/luck appreciation game, I don't see the point, go buy treasury/muni bills.

Ten-year Treasury notes to over 15%.

If you are the winning bid on a seized dept.of treasury auction,Does that erase the debt the property owner[s]had with the dept of the treasury[IRS]

The smaller the spread between cap rates and treasury rates, the hotter the market in my opinion.

They are providing money to domestic or international business to produce value for employees, customers, their local economy, and share holders.Even people who buy treasury bonds are adding value.

Treasury yield curve rate for 1 year, as of the first business day of each year, or 1.5%, whichever is greater, less any damages rightfully withheld.

Bernanke, in a speech in August 2012 said that when the Fed buys lots of super-safe assets like Treasury bonds or agency-guaranteed mortgage-backed securities, it pushes investors to buy bonds from corporations instead, thereby lowering businesses’ borrowing costs.
