Will banks / building societies give a 100% mortgage on a buy-to-let mortgage ?

I am wanting to earn some extra cash by buying property to let. I do have savings, but don't want to use them as a deposit, as I'd rather invest them in my own home. I am currently looking at homes in the �150,000 - �200,000 range that will probably give a return in rent of around 125% - 135% the cost of monthly mortgage repayments. Does anyone know if there are any providers that would loan me all the money required to undertake this venture ?
