I would just set it up differently than you have.Make your "purchase price" any up-front investment, such as furniture, decorating, web site, etc.Make your "mortgage payment" the same as the monthly rentMake your "rent" the net rent from the properties less any fees you pay to third parties, such as cleaning, advertising, etc

It’s about 8-10k to furnish and decorate. 

Bonus Points if you can refer Decorators/ Vacation Furnishers in Connecticut or Michigan. 

I want to be able to offer several options to sellers, including a quick sale at reduced price to investor connections, listing on the MLS if it doesn't make sense as an investor deal, and recommending anyone they might need (contractors, decorators, cleaners, etc) if they want to improve their property before listing it on the MLS.

I'm have also been involved in other businesses mainly import and distribution of Hamptons Style furniture and decor. 

Like in my Whiskey cabin I did a whiskey theme and added decor and barrels etc.

The deduction depends on the usage and that is determined via tracking mileage.If you put the car on display (not use) in your office or place of business as a decoration, maybe.  

Overlooking these things will result in bad reviews.Most importantly, is the home themed and decorated for the WOW factor?

You need good location, decor, amenities, and customer service.

Just wrapping up my furnishings for a 4-unit (8 bedrooms + 4 living rooms) and was getting ready to pull the trigger on ordering a massive amount of throw pillows for the bedrooms, couches, and side seating when I realized they were probably going to be tossed onto the ground and not used as intended, leading to dirty decorations that my cleaner would have to launder.
