Government designed it so the retirees would not be a burden on the government once they stopped working. 

Ok guys so I went to a school in Oklahoma City for a government job.

C is less stable, a lot of government assistance or less stable employment, people home all day, some crime (uncomfortable to spend time) but not super scary. 

Unless you are receiving government subsidy, or are considered student housing and so forth, there seems to be good cause to assume that you can refuse pets that don't meet the guidelines. 

Rachel Imhof Wow, so thorough and so great post, I could not agree more with #4, we have government contracts and when you say “we remodel government buildings” the usual reaction will say “oh that’s good money right there”, it is not, we spend efforts and spending a ton of time and money before and after a contract, chasing them and failed bids, then government tells you how much to pay workers, then there’s always that oops factor.

When we first started, we toyed with doing C-tier rentals but quickly abandoned it because the reality is so much different from what looks like amazing 'government guaranteed' cash flow on paper.

Guidance memos, regulations, and enforcement policy as issued by the executive branch of the government (whether state or federal) as well as case law further expound on the law. 

For a "conforming, conventional" loan (loans governed by Fannie Mae and Freddie Mac) they will use potential rental income for a purchase. 

Since your sister received a loan to purchase this property she would need to wait 6 months to receive a 'conforming, conventional' loan (a loan that is governed by Fannie/Freddie). 

For government loans, this is typically lower however, you would have to pay a premium up front and carry the insurance for life.
