Second Mortgage Shop

Hello, I've recently made a home purchase and will be closing on my new home in about three weeks. Since my credit score wasn't high enough to qualify me for a conventional loan, but income was, the builder's finance company was able to approve me for an FHA loan since it was also my first home purchase. My question is I'd like to put a pool in, I live in Arizona and it's a necessity in this state and was wondering if there are any stipulations as far as the amount of time I have to pay on the loan before I can pull a 2nd mortgage on it or refinance it to get some of the equity and put the pool in and make a few upgrades to the home?

I'm pretty sure there is no prepay on FHA loans. You can refi as soon as you want, you're going to need equity obviously and it doesn't look like you have any seasoning, that might be a problem. You're best bet is to find a broker and have him/her shop it around for you.
