In the current financial situation, I doubt an MBA will help (significantly at least).
I would not get an MBA just to get a loan - you will be spending a lot of money you could use elsewhere, so if anything, it will only hurt since you will have fewer assets and possibly student loans, thus reducing your financial position.
