If you need to find cash today, there are tons of different places that you can turn to find it. Most people will end up getting a loan, and there's a good chance that you will too, but if you can take some steps to reduce the amount of money that you need you will be in a much better financial situation. Same day cash loans are everywhere, but use the steps outlined here first so that you don't need to borrow so much.
First, take a look around your home or apartment and see if there is some stuff that you can live without. Selling your stuff to a pawn shop is a great way to get some cash instantly. All you need is things that have some resale value (video games, tools, bikes, jewelry, etc.), gather them up and head down to your local pawn. In order to get as much money as you can, spend some time cleaning the things you're going to sell up. Pawn shop employees are human just like you and me, so they think first with their eyes. If something looks like it's in great shape, they are more likely to buy it from you and give you as much as possible.
Second, find some odd-jobs that you can do to make a quick buck. You can gather up cans and bottles to recycle, mow lawns, clean houses, do some babysitting, or whatever you're good at. It's easy to make a couple hundred bucks in a single day by doing this, again greatly reducing the amount of money that you need to borrow.
After you've gone through those things, you now know how much you'll need to borrow (if anything at all!). You can get a same day payday loan at a local lender or online. Both of them will carry similar terms and rates, but online lenders tend to be a bit faster than the storefront type. Title loans are also a good option if you have a car that has been paid in full.
Getting cash today is very easy, but you'll have to put in some work if you want to get as much as you can without having to pay much back. Ultimately, it's your time and money and if you're more comfortable only taking out a loan, do so. If you're not sure how well you're going to be able to pay it back, do everything you can to earn some money now.
