So if you had 20 of them, you're talking about a huge retirement kicker that you can build.If you're up there higher in age (i.e. 40's or 50's), then the long play doesn't make as much sense. 

However, if the 401k has business income, it will be subject to UBIT.An IRA is not subject to capital gain taxes because it is a tax-deferred retirement plan.

Hi Kevin,It looks like you have some money saved, that's fantastic.

This can save thousands annually.  

After spending 25 years as a Software Engineering and Product leader, I’m now exploring the world of real estate investing (REI) and looking forward to learning from all of you.My goal is to leverage my current investments and savings to build a real estate portfolio that will eventually allow me to transition away from my current career.

My goal is reviewing retirement options. 

Cash flow is great when your houses are paid off and you're ready to retire.

I have one in mind at Rent to Retirement. 

We are trying to not use our retirement funds.

On the other hand, maybe you are going to lose some personal income due to retirement and want the cash flow.
