If you are a person with no credit rating, you will need to establish one before you will be able to get a small business loan. Basically, you establish a credit rating by buying things on credit and paying back the money you owe. Your loan repayment history plays a big part in establishing your credit rating, but all your "credit" dealings make up the history that's used to determine your credit rating.
The MBDA does not directly loan money, but it does provide resources for members of minority groups who are trying to start a business. They have business centers around the country where entrepreneurs can seek mentorship and guidance as they start their business. These business centers are located in areas with a high amount of minority-owned businesses. You can go to MBDA.gov/businesscenters to find one in your area where you will be advised on everything from writing a business plan so you can apply for funding to marketing your business.
When you get a HELOC your personal home will be used as collateral. This means that if you fail to make payments in the future then you could lose your home. That is the risk that comes with the benefits of receiving access to low interest rate funds as you need them. With a HELOC you can borrow up to 80-90% of your home equity with an APR as low as 3%. You must have a credit score of at least 650 to qualify.
