A $500k exemption means nothing lol?

If the property is financed in a self-directed IRA - there would be Unrelated Business Income Tax on the profit from leveraged portion of the property (truly self-directed Solo 401k plan would be exempt from taxes on leveraged real estate).There is no possible way for you to transfer existing property you own personally into your IRA!

You get up to 250k in capital gain exemptions if you sell your primary and you lived there for two of the last five years, 500k if you are married.

If you have a residentially zoned property, you may choose between Type A and Type T licenses.If in a residential zone, the next step is to determine if there is a homestead exemption on the property.

In addition, you will need to pay for a registered agent in each state besides the one you live in.While Nevada does not have a state income tax, this does not mean your income will be exempt from state taxation.You likely want to work with an accountant who understands the business of real estate and understands the expenses that you are entitled to take in addition to knowing the unique tax laws to real estate investors(1031, 121, etc)

Health/Medical care. 

Some qualified exemptions or hardships will eliminate the 10% penalty for early distribution. 

But I also got a LOT of multigenerational families applied.The 4 bedroom has a married couple and their one child, plus his retired police officer father and her medically needy mother. 

First I want to make sure they are ok and get any medical attention if needed.

Any lawyer in Texas will take that case on contingency because you have non-exempt assets.
