Flipping houses can be a wonderful thing to do for profit, but unless you have unlimited funds, you will need a loan. Lenders today look first and foremost at your credit score, and it will impact the terms on your loan, such as your interest rate. If your credit is not great, you should work to improve it right away by paying bills on time and keep the spendings low. Also, be sure to be aware of what not to do, so you don’t lower it by accident.
