With the exception of 1 bedroom units, you basically have 2 options:-Oversized/commercial machines (potentially multiple sets)-Off site cleaning with clean spares on siteThe latter is almost always the most efficient and basically what hotels do at scale.

If you self manage, you save that money, but you are basically taking on a side hustle.  

Basically this complex is six unit three-story and all one bedroom with 700 sq. ft. each. and street parking (no parking garage) Please let me know what additional info I need to provide to better helm me on this project.thank you 

@Dwayne RoweWe did a consolidation loan through a commercial banker (basically a multi-property DSCR loan) where we took out one loan that paid off 5 higher interest rate properties, and took out cash as well at the same time.    

You'd basically be doing it entirely new.   

Hawaiian real estate law differs from other western states significantly, mostly due to its monarchal heritage and the Bishop Trust influence.The basics are the same as would be in California; determine the condition of title ownership (individual(s), estate (including conservatorship, if appropriate) OR fiduciary acting for trust.Use a qualified private money equity lender to make a loan sufficient to buy out the cash-only beneficiaryThe legal community in HI and Big Island in particular is small.

You basically own 3 paid for properties. 

Just some basic stuff you should try to follow if able.

I ran some very basic numbers on option 1 and if you can get a ST/MT rental per your comments and other assumptions you list, this could be a deal for you.

Basically, the further you get away from the city the more potential for cashflow, but you're also dealing with a different tenant base that may be tougher to manage.
