For this answer assume you are asking me for the loan. Of course you can get financing. This haw I make my living.
Regardless of your credit score the process is the same. The hardship you anticipate is not as painful as you think. Here is what you need to be prepared to answer.
1. How can you afford to buy the home you what?
2. Since your credit rating is lower than some, you need to demonstrate you are committed to the purchase and your obligation to repay a loan. That means a downpayment of your own money. You lose your downpayment if you stiff me on the loan.
3. I assume risk by lending you my money, after all I want to make money not own a house where you painted all the walls black. The greater my risk, the more I worry about getting my money back, so your Credit Rating is my worry line. You make me worry, I charge you more than people who don't make me worry. That is in the form of the percentage you pay on the loan.
4. Bottom line is question number one. Can you put down enough of a deposit so that you can afford the slightly higher risk/percentage you pay for the loan?
