I do not think that loan is a good idea. A loan is a debt pit, from which it is difficult to go. I think that it is better not to do this if there is such an opportunity. I think it's possible to make the right amount, save it. Moreover, now there are many ways to make money without leaving home. For example, I earn money at sports betting. This is a very interesting way to earn money. I like sports, so it's fun for me. But it's not as easy as it seems. I use the information from https://fscore-bd.com . This helps me to make the right bet.
Both have their pros and cons, and in some cases can be better so it's hard to say exactly. Your choice will depends mostly on your current situation and budget because anyway you'll need to repay later all debts.
For example, payday loans are better as a really fast and short-term financial help. Appying for them is easy, can be made online and takes no more than an hour, as getting later your money in cash. There isn't much paperwork for their application process and your bad credit history can't be a problem for this https://paydayloan.network/emergency-loans.html .
On the other hand they have strict and short terms of repayment because payday loans are applied no more for a month and you need to meet their repayment terms later. Without this you'll get additional fees which are very high (and higher than in case of bank credits) and it's the same for their interest rates too. So there's always a risk for getting an even bigger debt than you had in the beginning.
They're safe as in you won't be arrested for taking one out, but generally I wouldn't recommend them unless you know you can pay them back quickly as they often have incredibly high interest rates and other fees for late repayment.
A line of credit is much like a traditional credit card, they usually have lower interest rates but the approval process is more time consuming and they are often secured against a large asset like your house. This was a pretty good article.
