It is good that you have an L-1 visa. However, how many years of a credit history in America do you have? A Lender may have to put together an alternative credit history for you. 5 months is a great start, but for international lending transactions, at least 2 years is preferred. Also, you will need 30%-50% down payment.
Also, you are going to need your down payment money in american currency, so if you need to transfer money for the down payment here from your native land, you're going to want to do that ASAP. An international real estate attorney with experience is going to be of tremendous benefit to you. I am on the Massachusetts Association of Realtors Global Task Force, and I'm a member of the International Committee of my local Realtor board so I know of some real estate attorneys who could help you.
