2Homeowners Policy Endorsement
It’s possible you might be able to simply add an endorsement to your already existing homeowners insurance policy. You might be able to increase your limits to include the cost of value of your business equipment such as computers. You also will want to double check to make sure your liability coverage is enough to protect you if clients or delivery people for your business come to your property and get injured.
If you don’t get a lot of visitors for your home business, then this will probably be a good option for you to explore. Be honest with your insurance provider and see if they will offer you something like this.
