ObedNyakundi/Rental-house-management-system ? reverse-engineered prompt

Build me a simple web based rental house management system for the Kenyan market using plain PHP with a MySQL database. I want a public facing site where people can view vacant houses or rooms, plus basic pages like home, about, contact, and a blog. Then add an admin area where I can log in, manage house listings, admit tenants, keep rental records, and view a dashboard with useful notifications and tables.

If possible, include the older style features this kind of system usually has, like SMS alerts and M Pesa payment support, but keep it practical and working over fancy. Make it responsive so it still looks good on a phone. Please also wire it up so it can run locally on XAMPP or WAMP with a database import and easy config for database and SMS credentials.

Keep the code straightforward and beginner friendly, and clean up any obvious security or stability issues while preserving the original feel. You can look up current docs online if needed.
