I wouldn’t recommend purchasing a house until you’re able to get your credit score up. The interest rates on your mortgage will be high with any credit score under the mid-700’s, which means that every month you pay your mortgage, a larger portion will go towards the interest than the principal. In the long-run, it could potentially get you into deeper debt. especially when you consider the increase in costs for maintenance as a homeowner (lawn care, unexpected plumbing issues, painting, furnishing the new home, heater and AC maintenance, property taxes, etc. ) Wishing you the best of luck in your fresh start!
