The USDA Rural Housing Service (RHS) program offers affordable housing finance options for very-low to moderate-income residents, providing benefits like no down payment and low monthly insurance rates. It encompasses two main programs—direct and guaranteed loans—catered to different income levels, with flexible eligibility criteria and no maximum loan amounts. Properties must be in eligible rural areas and meet specific requirements related to inspections and condition, while various resources are available for borrowers and realtors.
