make it a great day,
The more you put down, the lower your rate of interest will be. A good way to add a couple percentage points to your downpayment without stretching the budget is by getting a buy-side commission rebate from your real estate agent.

You may also contact a credit restoration company to give you some assistance to fix your credit prior to obtaining a home. Best of Luck!!
