According to Jain Dharma, there is no mantra that guarantees an instant house within 15 days.

For peace, clarity, and auspicious support, you can do this:

1. Navkar Mantra Recite it with faith, devotion, and a calm mind: “णमो अरिहंताणं, णमो सिद्धाणं, णमो आयरियाणं, णमो उवज्झायाणं, णमो लोए सव्वसाहूणं”

2. Practice daily

• 108 times Navkar Mantra
• Samayik if possible
• Charity according to your capacity
• Ask forgiveness for any wrong thoughts or actions
• Keep pure intention and patience

3. Jain view In Jain Dharma, results come through:

• right effort
• right karma
• right faith
• purity of intention

So instead of a “switch word,” the most powerful Jain sadhana is Navkar Mantra + right action + patience.

If you want, I can give you a very short Jain daily prayer for house-related peace and progress.
