Long story short - I have a neighborhood that I bought out of bankruptcy 3 years ago.  

I revised my goals downward so often I ended up with goals of 1) my marriage surviving and 2) avoiding bankruptcy. 

Many lenders will treat you like you have had a bankruptcy when you use them.

As a cash buyer, Would you buy a house with a tenant that has just filed for bankruptcy?

I assume you don't want to spend a lot of money on this problem but filing bankruptcy isn't free.  

Retirement accounts are usually shielded from litigation, bankruptcy and divorce.

The seller *may* be able to file bankruptcy, stop the foreclosure, clean out a lot of debt and still sell the house to you.

You'll usually need some sort of guarantor that will not declare bankruptcy the minute something goes wrong; too easy to do that in an LLC.Once you have a track record, private money folks will lend to you, and on larger properties (large MF) commercial real estate banking looks almost exclusively at the property.Spend some time researching the financing options.  

If someone like me who went through bankruptcy and lost everything can do it - and now acquired over 1,000 apartment units, anyone can do it.

@Klodian H.Please note that while there is certainly asset protection for 401k plans at the federal level generally, please note that for individual Solo 401k plans (as opposed to a 401k plan that you might have through a day job) the federal protection outside of bankruptcy does not apply such that one must look to the state level where the creditor protection may not be as robust.
