A. How about using the same fund to do both?
Most of the time, funds in a retirement account can only be used to stocks or mutual funds, but there is a special type of IRA account called Self-Directed IRA, it A Self-directed IRA allows the account owner to direct the account trustee to make a broader range of investments, including real estate investment.
The benefit is obvious with a self-directed IRA as your investment horizon is broadened significantly and you won't have tax issue until at the time of withdrawal.
As expected, there are costs involved in setting up and administering a Self-directed IRA account, the good news is, there are only a handful of firms in U.S. provide this kind of service, so you just need to compare all of them and select one you feel comfortable to work with.
