Rental Income as Roth IRA vehicle

I understand that IRA’s are primarily funded from earned taxed income. I have a Roth that is funded from after tax income from prior working years.

• It would seem logical then that I be able to add to my Roth from my * Taxed income generated from my Rentals ?

I looked it up and it states generally not allowed, but that was from a simple google search. I thought this body of knowledgeable individuals would know more specifically…

Thanks!

My memory of the rules is that you have to have earned income to contribute to a Roth IRA. Rental income is passive income and therefore would not qualify.

*That makes sense… Thanks
