If you are willing to inject a couple hundred dollars a month into the property what is that doing for your wealth?

Accounting measures would need to be documented properly if you are keeping books (which I would highly encourage you to do so) so "cash injection" followed by "loan" would be the proper methods to use if you are taking your personal funds and giving them to your company. 

Add a company that injects expanding foam under the foundation.

He got 3 hemlock injections with some gamma burst radiation, and that cured it.

You won't be living there, so try to not inject your biases.

You can administer the investments, but cannot benefit now by receiving income or inject benefit into the IRA through services like performing work on the property.If you get a good rental property in your IRA, for example, your IRA has a stable asset securing the principal, with consistent income over time and the potential for appreciation. 

The US spends about 6.4 billion a year in residential construction housing, so a one time 500 billion injection would be off the scale.   

I am currently working as mold maintence for an injection molding company the produces plastic auto trim.

Specifically having Termidor injected into the soil and spraying Bora Care onto exposed wood.  

But essentially I'd like to have a private lender inject some more cash into my funds to provide some octane and speed up my acquisition process.
