Printers are no longer a luxury item, they’re $100 and totally deductible. 

Thanks @Sarah Kensinger - this is a luxury RV lot that is gated and right on the water.

Running one AirBnB out of a studio apartment or mother-in-law suite is a great way to live for free and potentially cash flow.

With Florida being the hotspot for international investors, the mortgage process has adapted to suit.

The reality is ADUs, casitas, mother-in-law suites, etc have existed for decades, much longer than the fairly recent state level ADU laws some of which are already 5 years old.  

The new cabin would be a high-end luxury pool cabin with an unobstructed 160deg view like my other cabin.  

This would be the most work for me but I know where to go and putting in the leg work to get sturdy, luxury cabinets and finishes at auction and discount will be a big part of the strategy.

Standard too luxury, and several other factors vary it wildly. 

Some might have a strong NNN tenant in place with 10+ years left on the lease, and it might be a big corporation that you can take to court if they ghost on paying their rent, while others might be office suites broken up into small offices on 6-36 month leases with shaky tenants like a nutrition supplement MLM that uses the office for 3x a week rah rah meetings on how to recruit more people into the pyramid scheme, that are immune to law suits b/c you can't squeeze juice out of a rock.

I invest in mortgage notes, you can google biggerpockets note investor scam artist, fraud etc and will find many posts of people who had to file suit and were successful against a certain investor.
