Hi Hazel P:
Thanks for your questions. Generally, home mortgage loans offer lower interest rates than personal loans, business loans or investment property loans. The type of mortgage available depends on what the lender offers and what you qualify for. Generally, long-term fixed rate mortgages are the most common on primary residences, however, adjustable rate mortgages are an option as well. Some ways to take equity out of your home include taking out a home equity line of credit which is revolving and is similar to a credit card where you only pay interest on what you use. Another option may be a cash out refinance. This is where you obtain a mortgage to pay off your existing loan and take the difference in cash. This cash can then be used to fund your pet supply business. Here are a couple articles that I hope you find helpful.
Best of luck on your pet business.
