My interpretation of fair housing laws that everyone must be treat everyone equally and no one gets special treatment.

Is this what you are intending, because your statement above could be interpreted either way.An IRA or 401k can flip houses, but that type of activity is considered a trade or business, and therefore subject to taxation even inside a tax-sheltered retirement plan (so as to level the playing field for tax-paying businesses).  

I do this for all properties.Then I do this where H = predicted value, Y = actual valuepercentage_error = abs(1-((H-Y)/Y))I put these numerous percentage errors in a list.I take the median and it yields ~5%I perform a sample standard deviation on the list and it yields 20%.I interpret this to mean that roughly half of my estimates over estimate the price by more than 5% and the other half do better than 5%.

There may need to be some interpreting and I suggest to ask them here in the lender category for clarification.Best of luck!

@Logan Allec your interpretation of the code is correct.

@Tim Miller  -  The issue is that the "law" is extremely grey, and up to interpretation. 

It is tricky to navigate and interpret.

Whether they work depends entirely on how your local PHA interprets the rules and views the needs of your area. #1 Ask for a "Reasonable Accommodation".

My husband is self-employed as a full-time pianist/entertainer and I am employed full-time with W-2 income from my sign language interpreting work, so I'm sure that factors in.  

However, each county may have their own way of "interpreting" the law and/or applying the law, and/or chosen methods by which they apply the law.
