It is possible to w/d from your IRA penalty free for a first time home purchase. Although i think there is a limit of $10k.
If I restate your question as "Can I invest my IRA in real estate to increase my current cash flow?" It is possible if you are a qualified home buyer. There are exceptions to the penalties.
Here is the literature describing the exceptions to the 10% penalty from the IRS website.

To explain a little further...
So I suppose it is possible to withdraw money for your own house which would free up cash flow were you use it as a down payment if you don't already have it. The savings on your mortgage will decrease your monthly mortgage expense thereby increasing your cash flow. There are many rules that go along with this such as you must occupy the house for 5 yrs so I would probably it until you consult a CPA who can look at the specifics of your financial circumstances.
Hope that helps.
