So, when it comes to taking out a loan there's a few major things you should be considering. The order in which these appear will probably change depending on who you ask, but they'll usually all be in there. So:
Your Credit Score
What's your credit score and credit history look like? This is one of the major deciding factors in just how much you'll end up paying in interest, and ultimately how much you'll be able to borrow.
Rates & Fees
Rates and fees vary depending on who you apply to, and what financial institutes you apply for your personal loan from. Banks and Credit Unions, for example, both have wildly varying fees and considerations are a great way to explore those further).
Are You Eligible?
It sounds like a silly question, I know, but it's an important one! Are you eligible for a loan? Do you meet the loan provider's eligibility criteria? It may be worth checking before you invest time and effort into applying for a loan you won't get!
That about wraps up my major thoughts here. Hopefully that helps, and best of luck with your application!
