what's best loan to purchase rehab commercial building for my construction business

[Dan Hunt]

I've found a building I have the resources to repair and rent and use a bay for the business. I have perfect credit 20% cash down on 400k purchase. I own 3 single families free and clear their not used for income (2 vacation homes and a primary) 1st year business  gross sales 600k. The company has perfect credit. Is there a best 1st Business loan I should use?
