As you pray over your home I recommend taking oil and anointing every doorway and window throughout the house. As you go from room to room say the following say the first prayer. When finished pray for the whole house in a central area or outside (or both) with the second prayer. You will also want to remove all occult objects that you are aware of from your property if you truly desire to live in a sanctified home.
Room by Room Prayer
Lord you said in your word that he that dwells in the secret place of the Most High shall abide under the shadow of the Almighty (Psalm 91:1). I declare that this room is spiritually transitioned into your secret place and now abides under your shadow. I repent on behalf of every sin committed in this house including but not limited to fornication, idolatry, adultery, homosexuality, theft, coveting, drunkenness, revelry, and extortion (1 Corinthians 6:9-10). I declare that this property is now being transitioned under the jurisdiction of the kingdom of God and will from hence forth receive the blessings thereof. There shall no evil befall me neither shall any plague come near this dwelling (Psalm 91:10). I plead the blood of Jesus over this home and every person that presently resides in it because we overcame the devil by the blood of the Lamb and the word of our testimony (Revelation 12:11). I now speak to every spirit that has taken up habitation in this dwelling place and I take authority over you according to my authority in Jesus Christ. I cast you out, and command you to go to where the Lord Jesus sends you.
Speak this Over the Entire Home
To every evil spirit that has held influence over this home, I serve you an eviction notice and I divorce you from this property now in the mighty name of Jesus. If there are any hidden objects providing rights anywhere in this house or on this property I declare that they are immediately exposed, that they are absolved of their demonic power and that all rights are cancelled in the name of Jesus. I speak over my home and declare that it is a habitation of righteousness, and a dwelling place for the presence of God (Exodus 15:2). I close off former satanic access points and I decree that every portal and window of access to the demonic realm is now being shut and sealed in the name of Jesus. I declare that the Lord will now be a wall of fire round about this home (Zechariah 2:5). Thank you Lord that this home is now being surrounded by angels above and below and against every dimensional access point in the name of Jesus. Lord I thank you for delivering my house and property from the curse, for it is written that Jesus became a curse for us (Galatians 3:13), and I thank you for filling this home with your glorious presence. Amen.
