If you don’t want to contact a bank just yet, there are several mortgage calculators online that will tell you a monthly payment. Keep in mind that house insurance and property taxes can add a little or a LOT to your monthly mortgage payment. We’ve been happy homeowners for about 5 years. When I look back and think about the money we wasted renting, it makes me so happy to have purchased. Especially the equity we gained from selling our first house to buy our current house! It’s worth it in the long run (especially if renting is = to the price of buying!)
Lots of big decisions! Good luck to you!
