Yes you can, but there are ways to increase your FICO so that the terms are even better for you.
1. I know you have other CC, but open a Secured card. Typically you can open one with $300. Every month put $100 into the account thats backing the card. This could add 30-50 points to your credit score.
2. let your credit card balances begin to revolve a bit. BUT, never have more than 25% of the card's maximum spent out. Try to keep each card above 10%. They want to see that you're ussing the card and paying it back, but still letting them keep their piece of the pie.
3. How many CCs do you have? What's the total Credit Limit for the cards? What's that compared to your income? If it's more than 50% of your income, you might want to close one card. If it's less than 10% of your income, you might ant to try to get another small card. Again, they want to see that you're getting credit and using it, but not over leveraging yourself.
4. When it comes time to go loan hunting, don't just go to one bank, heck don't even just go to 5. Try atleast 10 (unless all five of the banks give you excellent offers, then you can probaly go with one of them).
5. When the first bank runs your credit scores, ask them what number they got. Then, when you go to the following banks, you can just tell them what your credit scores are. Reason being, each request from a lender on your credit deducts 3-7 points from your credit score for 90 days. If you go to 5 lenders, your credit score might be depressed as much as 20 points when the 5th guy runs your score.
Once you get into your home there are a whole other can of worms that will allow you to pay your mortgage faster and even allow your savings to depress your monthly mortgage interest.
Congrats on the engagement and pending nuptuals.
