It's a great program if you are interested in buying in a USDA zone. Thankfully the maps have not been updated this year, so you have a lot more options of where you can live. Just make sure you qualify, because there are income restrictions with this program. Wake County is $91,850 for total household income up to 4 people, and $121,250 for 5-8 people. The other surrounding counties have lower limits.
If you're a first time buyer, you can always do FHA with the North Carolina down payment assistance of 3%, which will get you in the door with about .5% down. This opens up your options of where you can buy a home, because it doesn't have the same restriction as USDA. Your interest rate is a little higher, but the DPA becomes free money if you stay in your home long enough as a primary residence.
First time home buyer also can get the MCC program which is up to $2,000 a year tax credit as well. There is a formula to calculate what your rebate is, but if you spend about $150,000, you will get the full amount. It's like a free mortgage payment or two every year
