I don't use any 401K, Roth IRAs, IRAs, 403(b), SEP, SARSEP, ESOPs or any other retirement plans permissible under the IRS Code since such plans are not available in Canada. 

However, we do have a number of retirement and savings plans available including RRSPs, RSPs, IPPs, RRIFs, CPP / QPP, TFSAs etc.  There is also the OAS and GIS for qualified individuals.  Some people pull equity out of their real estate and/or sell some of their real estate properties or other assets as well.

Oh, and I can't forget the new and exciting Ontario Retirement Savings Plan that will come into effect for Ontario residents in 2017 courtesy of our Ontario government.  I haven't yet read the rules on that one (not sure if all of the rules have been released yet), but it will certainly affect self-employed individuals.

My best results came after hiring an asset manager to advise me and manage our retirement funds. We use Wetherby Asset Management in San Francisco.

Every real estate agent should try to take advantage of the maximum contributions to retirement accounts. 

Same here use SEP IRA. Every year!

I started with a SEP and then decided on a Solo 401k.  It's a good idea to get into the habit of living below your means.

 Good Wednesday morning Hank. I do my best to set aside about 10% to go to my emergency funding.

Hank - I am hoping my wife's retirement will help a great deal, and I don't really plan on retiring from real estate. I also have started investing, and am hoping that will help as well. I have other retirement funds from other jobs I have had prior to getting into real estate, so hopefully it will all add up to something.

SEP IRA, financial advisor, invest as much as we can while we can.  Diversify investments.
