Don't make a big financial decision when you're stressed or excited. Sleep on it. The dealership, the realtor, the salesman all want you to decide RIGHT NOW because pressure works in their favor. Walking away is always an option.

Pay off your highest-interest debt first — that's almost always credit cards at 18-22%. There's no investment that reliably beats paying off an 18% credit card. It's a guaranteed return. Knock that out before you even think about the stock market.

Taxes are the part everyone forgets about. Whatever you're planning, factor in what you'll owe Uncle Sam. Talk to an accountant — a good one saves you more than they charge. H&R Block is fine for simple stuff but get a real CPA if it's complicated.

I'd talk to a few different banks and credit unions, not just the first one. Rates and fees vary a lot. Credit unions especially tend to have better rates than big banks because they're nonprofit and member-owned. Always shop around.
