I have quite a few clients who self manage their vacation rentals from the mainland.Here is info directly off state of Hawaii website pertaining to vacation rentals (bold in mine):  If you’re off-island, you’ll need to designate a local contact who resides on the same island as the transient accommodation.

With that said, the buyer can still proceed with the sale if they are comfortable & able to overcome the appraisal gap and/or a solution is worked out financially between buyer and seller to make it feasible.So if appraisal gap is a concernBefore accepting:- Ensure the sales price on the contract is inline with market expectations. 

I was just gonna say, if you look at baby boomers, those who were in blue areas are probably going to be able to retire more comfortably than those who were in red areas. 

Regarding renting the mobile home, it depends on your comfort level with the types of clientele the home attracts.

I usually will say who referred me to them and say that they are a friend, neighbor, family, etc and will then ask what their lead times usually are for work to be completed, how they communicate, are they comfortable working with me being out of state, how do they collect payment (terms and preferred method) and do they offer a business rate?

When they see multiple new construction projects around the area they are more comfortable making their decision to rent your unit. 

Not all buyers may be comfortable or eligible to take over an existing mortgage in this manner.Feel free to reach out directly if you have any other questions!

You can also offer to be there on site while they are out to make them feel more comfortable.

They can't be vague and are specifically designed not to be left open to the subjective interpretation of a fact finder. 

@Jagan ReddyI'm not a CPA or a cost segregation specialist, but I do know that if you are not designated as a  real estate professional, then you can only offset passive income by your passive losses.Qualifying as a real estate professional is more challenging than most people want you to think.
