The numbers aren't really adding up for me.

AirBnB will remit to the county but I'm not sure if the tax will just be added to the rate, like a hotel, or handled differently. 

By adding tile floors, new cabinets and counters, new fixtures, new applicances, I think I should be able to get $1900 for rents no problem.I have not done a renovation of this scale, so if anyone can recommend contractors in Honolulu, Millani, Kailua, or Oahu in general that would do this kind of work, please do here or PM me.Also, I have no idea if I am able to write most of this off as repairs, or will I have to amortize the cost (not favorable)?

If we are adding any square footage of livable space to our property shouldn't the value go up? 

This is a D (F if your scale goes there) area.

If the sellers won't budge on price, I think  the foundation work would cost you about a third of your ARV  without adding net value to the property.

The tenant pays the electric, which has added to the incentive not to run the A/C.

Usually once a thread gets past the first page, either the persons original question has already been answeredThere have been several follow up questions askedAn entirely new discussion (debate) has broken out in the ensuing pagesAs a result of these things if I don't read all of those long threads I view my post as being non-value added to the conversation, so I don't make it. 

Account Closed In addition to the other good advice here, remember that you don't have to jump to show your rental the moment that someone wants to see it.I'd recommend saying something like this in your ads:  "Two Group showings only. 

You might also consider a couple of diffferent digital ads to put together yourself and that way you could also put them up here and don other social media.
