Thank you. So you are saying that even though the piece of let-to-own property is generating rental income that income is only going back into the retirement account and is therefore not creating any realized gain? I'm pretty sure that is what you mean and that is certainly how it would be handled from a tax perspective in the USA. I thought I'd double check though.
Also: I am assuming that when this retirement account finally does liquidate then any liquidated amount will be classed as income in the tax year of the liquidation and it will taxable at whatever tax band the account holder is in the tax year of the liquidation?
