SDIRA into a new condo deal?

[Pat Bahn]

this is a hypothetical, but suppose
you were interested in a small 10 unit MFDU.
that can get a little pricy of an investment, so, you
want to create the unit as a condo, so it's 10 units,
and the SDIRA buys say 6 of them and you buy 4 of them with
cash funds.

would this pass muster with the IRS? if you kept clean books and the IRA got it's rents and you did with your 4 units as you see fit?
