DEFER TAX PAYMENT
The tax on the earnings of a Traditional IRA are deferred until withdrawal. Therefore the taxes that should be due are continuing to earn additional value and will do so until the funds are withdrawn.
Taxes are paid on withdrawal of the funds at ordinary income tax rates (25-35%). Never put real estate in a traditional IRA. Real Estate is taxed at a capital gains (15%) at the time of sale. That beats 35% which you could pay on your traditional IRA.
