I'm a first time homebuyer, and I want to try to do this?

I want to get a mortgage for more than what I'm going to pay for the house but for less than what the house is worth. If I do go through with this I have to use my mortgage to pay my truck off. I know this is not the ideal way to go at all, but I do not plan on moving. Im getting a really good deal on the house and just for numbers sake it's listed at 108,000 and I will probably be giving 60,000 for it. Assuming the appraisal goes well, would a my credit union or any lender be willing to give me more than what I actually pay? Thanks!
