Buying into a franchise group is considered more financial viable than a start-up business unless you have been operation part-time for the last 2 years from your home or home-garage. Unless you have brick & motor security most lenders give start up business a wide berth, or advise you to come back when you show some profits.
However if you are purchasing an approved franchise group and require finance, most lenders will consider lending a percentage on the approved list of franchise on their panel.
If the franchise group in on a particular lender panel, means they have meticulously run the figures on the franchisor to approved a lending percentage they are willing to sign off on from 35% to 75% of the value of the Contract Purchase plus the Franchise Fee, Goodwill and with a few lenders the Stock on Hand.
The balance of funds which you have to contribute can come via cash or equity in property to assist with the purchase.
