Not really any products out there that I know of that do 10% down on non owner occupied property, not that I've looked lately. There are some that will go 100%, but only up to 65% of market value, so if you are stealing the property you can do that, but if you are paying anything near market for the property I don't think you are going to find anyone to loan you 90% no matter what your credit score is.
You might could find someone to loan you the difference if you've got good credit and a stable job, but most lenders want to know that the down payment isn't borrowed. They kinda shy away from the 80/20 stuff we used to do these days, but it can still be done, especially if you're using private lenders for the 20. I do my stuff financed at 100% all the time by using cheaper bank(ish) money first and private money behind it.
If you did find someone to lend at a 90% LTV the rate is going to be way higher than a 30 year fixed FHA loan, just FYI.
