You can't use a portfolio loan to buy a villa. Portfolio loans include commercial loans and provident fund loans. Generally speaking, commercial loans have no restrictions on villas, and provident fund loans are different. Provident fund loans can only be used to buy ordinary houses, and ordinary villa projects are not up to standard in all aspects, so the provident fund loans for buying villas cannot be approved. Without provident fund loans, it is natural that portfolio loans cannot be used.
