The cost of boarding houses for the elderly in the Philippines can vary widely depending on the location and amenities offered. On average, you might expect to pay anywhere from PHP 10,000 to PHP 30,000 per month. This typically includes meals, basic care, and accommodation, but additional services like medical care or personal assistance may cost extra. It's a good idea to visit facilities and inquire about their services and fees directly. For specific information, checking with local providers or government resources can also be helpful.
