I agree with SJ. You can do it. You better get professional advice.
Even though we deal with income property in our business, anyone wanting to do this we refer to outside experts. There are many pitfalls. One, for example, is the property tax issue you mention. If the IRA trust does not pay it, you have violated the IRS rules on the matter. (Upkeep and management, same issue.) I'd have to look up things as to what might happen in this case, but I assure you it would not be good. (Breach of the trust, making all taxable or excise tax are two possibilities which come to mind.) Also, you have the sale problem for minimum distributions. No one should have all their IRA in properties.
Most who want to do this buy income properties which generate income. It's not as big an advantage to shield capital gains through property appreciation. While I can understand looking for an investment from a big portion of cash sitting in an IRA, putting it in property is a very aggressive choice. You need to be made aware of the risks and it is not for anyone but a sophisticated investor. (Well, maybe a REIT investment for average guys like me, but not direct investment.)
Be very careful. Even if done right, you may have done wrong.
