If the ownership of a home changes while a vampire is still inside, there can be very violent side effects.

Elijah was able to bypass the protection of the Guerrera Mansion in a similar manner by having a city official to invoke eminent domain upon the home, giving it heritage status and therefore making the home open to the public without invitation. This was seen when the Salvatores opted to bestow ownership the Salvatore Boarding House to Elena so she could use it as a safe house after Klaus came to Mystic Falls. Ownership can apparently be tampered with, as the magical protection is based on signed legal documents. Some vampires even go so far as to compel their human title-holders not to give a specific vampire entry, such as when Frederick compelled Miss Gibbons not to allow Damon to enter her home, where Stefan was being held captive and tortured. Vampires have been known to use this weakness to their advantage by establishing a home with a human owner so as to keep other unfriendly vampires from gaining access to their homes without invitation. Other methods of destruction will often yield the same effect, such as when Klaus started throwing fence pikes through the Gilbert House when he wasn't immediately extended an invitation.

Vampires who are unable to convince a human to invite them into their home have often been known to resort to other methods to enter the house, such as setting the house on fire to either destroy the home or to drive the humans inside out of the house and the protection it provides. If a homeowner dies and is then resurrected, the magical invitation barrier is 'deactivated' despite the owner returning to life, and it is unknown if the ownership can be refreshed in the case that this should happen. If the vampire is invited in, the barrier magically disappears, and if the owner dies or is killed, the house will no longer have an invitation barrier so long as the house's ownership doesn't revert to another person, such as if it's left to a family member in a will.

The barrier only holds for as long as the vampire remains uninvited, the owner(s) remain alive, and the dwelling remains standing. These invitation barriers are extremely strong, as they are among the few known ways to keep vampires at bay, if killing the owner is not an option. This was demonstrated by Jo Laughlin, who invited Stefan Salvatore into the Parker House despite the fact that she hadn't been there in almost twenty years, and that she was in Mystic Falls, Virginia while he was 3,000 miles away in Portland, Oregon. This extended ownership even continues long after a person who has lived in the house for a significant amount leaves, and an invitation into a home can be extended even over the phone from thousands of miles away. An invitation into a home may also come from someone who is either currently residing in the house or who has in the past, as they are, by extension, also receiving ownership from the actual owner(s). This protection appears to manifest itself as an invisible barrier that automatically erects itself on the door lintels and any available entrance in a human home if a vampire tries to enter that dwelling without an invitation from the owner. Whether or not the invitation to bypass thresholds is exclusively a 'spell' decreed by the Spirits or a 'supernatural law' set forth by Nature remains unknown. The events surrounding around the invitation's creation, beyond the direct consequence of the creation of vampires, has not been made clear. Since they signed over the deed to the place to Freya, he couldn't get in unless she invited him. Seemingly contradictory to this, in Where Nothing Stays Buried, Van explains to Lucien that it wasn't magic keeping him out of the Mikaelson home. This spell is absolute with no known magical loophole and the only way to reseal a house is to sign over the deed of the property to someone else. In Never Let Me Go, however, Bonnie explains to Matt that the reason vampires are unable to cross the threshold of owned property by the living was due to magic, a threshold spell. While Esther was able to find solutions to some of the consequences, this has remained absolute and neither Rebekah nor Esther offered any more information. Rebekah recounts in Ordinary People that after their transition, neighbors who had opened their homes to them could now keep them out. When Esther first turned her children into Original vampires, the Spirits turned on them and Nature fought back.
