They will never get "justice" in this situation.  

If you're investing in real estate, unless it is value add forced appreciation, invest for cash flow, and any appreciation beyond the rate of inflation is just icing on the cake.

@Sherry Justice These are all great questions and depends on the market.

“Our legislation would not only strengthen disclosure requirements and protections for homebuyers, but also help expose bad actors and facilitate their prosecution.”John Henneberger, co-director of the Texas Low Income Housing Information Service said: “These bills will help consumers be more informed about risky wrap-around mortgages and better protected from unscrupulous lenders.”Trish McAllister, executive director of the Texas Access to Justice Commission, added that the legislation will help families stay in their homes.

Its hard to believe this type of thing can't be tracked and the crooks wouldn't be brought to justice. 

Tax savings is just icing.

To the extent that you wish to trust the demographic data entered by the loan originator, Home Mortgage Disclosure Act data is publicly available so social justice groups can sue lenders for unlawful discrimination if the data indicates that is warranted (Wells Fargo etc).CFPB has an interactive website that lets you play with the data.If there is something unique about properties in the area you want to buy in that you want to get in front of, nothing will beat picking up the phone and calling agents in the area.

The following is copied from disabilitylawco.org.First, although the ADA and the Department of Justice’s (DOJ) implementing regulations have limited a “service animal” to a specially trained dog (or in some instances a miniature horse), those limitations do not apply to the Fair Housing Act (FHA) or Section 504 of the Rehabilitation Act of 1973 – the federal laws that apply to housing.It means that people with disabilities may request a reasonable accommodation to allow an emotional support animal to live with them even if their housing has restrictions or prohibitions on pets.The issue then becomes whether the person with a disability needs the animal in order to have an equal opportunity to use and enjoy the housing or housing program.

Our Department of Justice,  under the leadership of Special Prosecutor Lenny Breuer  and FBI, failed to bring to justice these greedy, self serving people. 

That is very hard to define, but as Supreme Court justice Potter Stewart famously said "I know it when I see it."
