Existing Airbnb-Commercial realestate ? conventional? ideas?

[Kaloa Devine]

We found an Airbnb property that went on the market.  12.5 acres, a 4/2 home, and 4 cabins w/ kitchenettes and Bathrooms, and another outbuilding that has a laundry room and a full bathroom for guests (they also have some glamping type spots). asking is 925k   They are saying 109k gross income a year from the rentals (this looks to include renting the house on Airbnb), I'm still waiting on additional financials, so there's lots I don't know yet. 

We would love to add this property to our little vacation rental business. Currently, we own (and live in) a building with basically a mother-in-law apartment that we've been renting successfully for the past two years. We do not want to sell or even mortgage this building if we can help it. 

If we can make this happen, We'd like to live in the home on the new property and rent both the units out where we currently live. This would get us a larger home and office (we have 2 businesses we work from home and we need the space) and a total of 6 rental units plus the glamping spaces.  

So the question is.... what's the best way to finance this? what type of loan? commercial or residential or ??   And is there any way to do this without pulling downpayment funds out of our current home?  Or at least as little as possible, I'm over 60 now and would rather keep totally paid-off properties, paid off. TIA :)
