Yes but you will need to look for a local commercial bank to facilitate a HELOC or try a commercial lender for a traditional cash out loan.

  (2) Variable cost: platform fees from Airbnb and VRBO, lodging/hotel/transit or whatever pass-through tax your local AHJ requires, cleaning fee, cost of replacement for consumables, repair and maintenance, etc. 

Honestly have never touched the traditional mortgage side of the bank. 

On the RE side - I own/developed 2,000 residential units across the United States focusing on opportunistic residential acquisitions and development, including student housing conversions and luxury multifamily development.On the startup side - it is a third-party guarantor platform that expands your renter pool, increases rents and occupancy, and ultimately boosts your NOI while broadening affordable housing options for renters.

However, I am unfamiliar with any lenders having traditional mortgage options for anything with a VIN number such as a trailer.
