Most credit items like biz LOCs and biz loans won't report on your personal accounts, but a rare few will. Definitely worth asking them. There'll be an inquiry though; you can always explain that easily w/ your lender-to-be.

It really depends on how you will be purchasing the equipment.. A loan though the dealer or on a company credit card.. Most direct loans shouldn't report but you would want to check and a lot more credit card companies are reporting.
