With Fannie & Freddie's regular financing programs, it permits up to 85% financing, but very few lenders have a mortgage insurance provider that insure investment properties (more will begin soon), so with most lenders you'd be looking at a minimum of 20% down, but 25% down will get you better priced interest rates.
