设计一个面向对象的售房中介程序，我们可以从定义几个基本的类开始，例如House类来表示单个房源，RealEstateAgency类来管理房源信息的录入、保存和检索。下面是一个简单的示例代码，实现了您所需的功能：

class House:
    def __init__(self, address, price, unit_price):
        self.address = address
        self.price = price
        self.unit_price = unit_price

    def __repr__(self):
        return f"House(address={self.address}, price={self.price}, unit_price={self.unit_price})"

class RealEstateAgency:
    def __init__(self):
        self.houses = []

    def add_house(self, house):
        self.houses.append(house)

    def save_houses(self, file_path):
        with open(file_path, 'w') as file:
            for house in self.houses:
                file.write(f"{house.address}, {house.price}, {house.unit_price}\n")

    def load_houses(self, file_path):
        with open(file_path, 'r') as file:
            for line in file:
                address, price, unit_price = line.strip().split(', ')
                self.add_house(House(address, float(price), float(unit_price)))

    def search_by_price(self, min_price=None, max_price=None):
        result = self.houses
        if min_price is not None:
            result = [house for house in result if house.price >= min_price]
        if max_price is not None:
            result = [house for house in result if house.price <= max_price]
        return result

    def search_by_unit_price(self, min_unit_price=None, max_unit_price=None):
        result = self.houses
        if min_unit_price is not None:
            result = [house for house in result if house.unit_price >= min_unit_price]
        if max_unit_price is not None:
            result = [house for house in result if house.unit_price <= max_unit_price]
        return result

# 使用示例
agency = RealEstateAgency()
agency.add_house(House("123 Maple Street", 300000, 200))
agency.add_house(House("456 Oak Avenue", 500000, 250))

# 批量保存房源信息
agency.save_houses("houses.txt")

# 批量加载房源信息
agency.load_houses("houses.txt")

# 按总价检索房源
print(agency.search_by_price(min_price=300000))

# 按单价检索房源
print(agency.search_by_unit_price(max_unit_price=250))

关于参考资料，您可以查看以下资源来进一步了解面向对象编程和Python编程实践：

1. Python官方文档：https://docs.python.org/3/
2. 《Fluent Python》一书，作者Luciano Ramalho，提供了深入的Python编程技巧和最佳实践。
3. 在线教程和博客，例如Real Python，提供了许多面向对象编程的教程和示例。

请注意，上述示例代码是一个基础的实现，实际应用中可能需要更多的功能和异常处理。
