Most banks will fund (mortgage) you as long as you have an initial startup fund and business plan, its the same as a house mortgage, as long as you keep the payments up to date you have no problem, but fall behind and they are straight on you, i think they wanted me to have 30% deposit when i was looking to buy premises, and as Jamers says any business can be a good business, but make sure you do your homework before you take the plunge.
