It is not uncommon for partners to buy into the company using a loan from the company itself. If this is the case, you may be concerned about the impact this will have on the amount you can borrow. The good news is that it is still possible to achieve a mortgage with company debt. Lenders will need to understand the size of the debt, the general credit history of the business, and other financial information. But, essentially, as long as the repayment of the debt does not impact your income, your chances of success shouldn’t be too badly affected.
