There are a few small steps you can take to improve your credit somewhat and increase the odds that you will get a better rate in a low-credit loan situation.
Pay off any Collections on Your Credit if Possible
Lenders are greatly impressed by the effort that potential borrowers put into cleaning up their credit score before seeking a loan, even if it doesn't directly or immediately improve your score, bringing proof to a lender (receipt) that you have recently paid off a collection on your account.
Make Payment Arrangements for Debts You Can Not Pay Immediately
Again, bringing proof to a potential lender that you have entered into payment arrangements with other creditors is a good sign to them of your sincerity and willingness to work to pay off your debts. Contrary to popular opinion, banks aren't always just about numbers and a credit score - they also concern themselves with the behavior and spending patterns of potential borrowers. Showing lenders that you will negotiate when things get difficult for you, is one way of impressing on the bank that you are worth lending to.
Get a Co-Signer
If you know someone with good credit who is willing to co-sign the mortgage with you, you will be in a far better position to negotiate lower interest rates with a potential lender. A co-signer represents a "safety net" to lenders as a second way to try to recover their loan if you find yourself unable to meet your obligation.
