Tina and Larry have put forth good answers. The best advice is to speak with a loan officer that is familiar with your situation. It will depend on income, debt, and credit score before you both and also when you will be married. I have had many clients in this same situation and my loan officer has helped them tremendously.
If you would like I can have them touch base and answer all your questions. Just send me a message. By the way are just looking in Aren Dills or you other surrounding neighborhoods like Shoreview, Roseville, and New Brighton? Thanks and good luck!
