I'm considering investing in one and sending it to my realtor to provide 360 photos instead of stills.

We are planning to list around 360k per house and will likely stage them, get a full set of photos, and a drone video that i'll be happy to share.

Every building in Waikiki is governed by their own owners associations, and a big majority of these associations actually despise short term or vacation rentals in their respective buildings.

Their answer will be the starting point for negotiation and you are showing respect to them by letting them be more involved in their fate.

As used in this section, the terms "owner", "junior mortgagee", "junior lienholder" and "purchaser" include their respective personal representatives, heirs, successors and assigns.There is no such language in the provision regarding surplus.That's not to say the current owner could not have an equitable claim against the trustor... but the way I read things the surplus goes to the borrower.

Would love to see some photos.

Maybe a photo of it with redacted names?

Maybe photos, a video, or ?

If you treat the borrower right, are respectful, are honest, and genuinely try to reach some sort of agreement, I think that your chances are low of being sued or complained against. 

You could just do  a quiet title action and take possession in that respect.
