So they would only have to meet your income requirement based on the 300 a month they are responsible for   The government  pays the other 600.  

I've heard that on government jobs, the spec book is several inches thick.

In 2012, the Danish government sold 10-year government bonds a -.32%.

In many instances a large portion of the rent is almost guaranteed to hit your pocket each month - again, this may not cover the full amount but they are consistent payments coming in (paid by the government).

This is how the economic “meltdown” (dow still over 25k, a record not long ago) is shaking out at the moment Interest rates are going down because world governments are just printing money to pay their bills.  

I thought interest rates are set and tweeted periodically by the federal government, no?

The Federal Government pays your rent direct deposit every month.

The federal government does not set private sector mortgage rates, we aren't in a communist country. :) The federal funds rate is just the rate that the Federal Reserve Bank will lend at overnight to private sector banks, what those private sector banks do is then entirely up to them, but obviously borrowing at a daily interest rate and then lending for 15 or 30 years isn't what they are doing (they'd go bankrupt).That being said, that rate on a 15YF seems absurd.

My question is, would it be better to start a new LLC specific to my real estate investing path or should I look at doing a DBA while still using the entity's official name on all government documents?
