$500,000 private funds question

[Jeff Fairchild]

I've seen an ad in the paper where the investor was looking for people with I think a self directed ira to put up funds into houses. Is this a good way of looking for private financing?

I'm looking for a way to buy houses very fast without using a hard money lender and without an equity partner. I've heard of doctors/lawyers loaning like $500,000 out at like 8%. What is that called and what would be the best way to find someone like that. How fast would that person be able to acess their funds?
