Home buying????

My husband and I are looking into purchasing a home. We are still working on our credit. I currently have none, and his is really good. They consider great credit a 730 and my husband's is only like 20 points below that or something like that. He brings home about $800 every 2 weeks. I will be bringing home about $500 every 2 weeks and it will be more as soon as they put me over to full-time hopefully in about 6 months or sooner. We just got a credit card with a max of $500 on it so we didn't go crazy on our first ever credit card. They said our credit should go up quickly if we pay it off on time. Do you think we'd be able to get our dream home (last photos listed)? We have a real estate agent that says there is a program we could do where we would have no down payment.

These are a few examples if the homes we have in our area.

This is a $94,000 home. 2 bed, 1 or 2 bath and it's nice on the inside.⬇

This is a $115,000 home and it's nice on the inside. I like this one.⬇

This is a $159,000 home. It's beautiful inside, but doesn't have much of a yard. We like it though. ⬇

This!! This is my dream home!! It's $169,000! I LOVE IT!!! I want it so badly!!! ⬇
