Honestly
I wouldn't listen to the previous post, IMHO. That your financial situation isn't TOO tight? Is that worth gambling on? What happens if this backfires and you can't find a suitable buyer? How much money are you willing to lose? In a loan, what can you offer as collateral? Are you willing to give that up?
It's like the lottery. It's like blackjack. It's like poker. All you see is the possibilty of making a lot of money. This possibility blinds us to what we should be thinking about equally as much. What are you willing to lose?
Then there is the theory of opportunity cost. What else could you do with 25K that would earn you money? Lots. A savings account won't earn you much, but it won't lose you anything either. Your age comes into play too. I would just ask that you carefully evaluate this situation...
Because I know nothing about you, your financial situation, career or domain name for that matter - I can't tell you what you should do. But, perhaps what you should really do is ask people more knowledgable than us. Speak to a loan officer... the conversation is free. They will be able to advise you best from a financial standpoint.
I would love a PM to hear what you decide. Goodluck, and I hope I've helped.
