I am wondering if I can use ifunds in my SIPP to provide a deposit on commercial property using the following method :

Another way the SIPP can be used is through a ‘joint’ purchase between you and your SIPP. So for example, if you have £200,000 in the SIPP and you wanted to buy a property for £400,000 you can buy the property jointly with the fund and yourself. So in this example, with the property being bought for £400,000, if you decided that £100,000 (25%) of the property is to be purchased (and therefore owned) by the fund, and £300,000 (75%) by you (being financed perhaps by a mortgage), then 25% of the rental income derived must be put back into the SIPP and 75% can go to you.

Do you know it this method has been tried and tested, and of a SIPP provider that would be willing to purchase a property in this manner. I have been looking at overseas commercial property aswell
