If you have to finance the purchase of a laptop, I'd be wondering if you should you be buying one in the first place? Perhaps the better idea would be to buy a used one and save up for a new one. You can buy an ok one for $500 and many people at this point can get by with an android tablet + keyboard. Also, +1 on what do you need it for? If you're just doing email and typing, a cheap alternative would be a raspberry pi + hdmi cable + existing tv or free used one + used keyboard + an SD card. Probably would cost you less that $100 all in.
