Have an honest talk about where you stand financially.
Crappy credit, colossal student loans, piles of credit card bills? In order to understand what each of you can reasonably afford, you need to come clean about what you pull in and what you spend on a monthly basis. Figuring out your cash flow also plays a part in how you’ll divide day-to-day expenses and utility bills.
It might be awkward, especially for couples who aren't ordinarily open about their finances, but it's crucial to making a sound decision about your living situation. The last thing you want is to enter into a lease together on an apartment one or both of you can't afford, and end up struggling to pay rent. Or, worse yet, supporting your significant other.
Having a clear picture of one another's finances helps you make smart decisions, and saves you headaches down the line. Trust.
