Household surveys are generally divided into two situations: 1. The borrower applies for a loan from the bank in his own name, and the bank's investigation procedure requires on-site investigation of the borrower's address and on-site examination of the real estate license and land certificate provided.

2. It is the loan applicant who uses his own or someone else's house as collateral, and the bank's investigators should verify the collateral.

Household survey means that the interviewer goes to the designated interviewee's home, directly contacts the interviewee, asks questions one by one with a structured questionnaire, and records the other's answers. Or give the questionnaire to the interviewee, explain the filling requirements, and wait until the other person fills it out before receiving the questionnaire.
