Added some decorations and turned the workshop garage into a game room.

Or I might just rent the place and disclose to renter that the fireplace cannot be used and is only for decorative purposes since there is HVAC inside the house.

The only downside is you have to have the right wall to put them on and it is not the most attractive wall decor.

Wall cladding is a great way to add impactful decoration and style to your interior design.

Landlord shall not be obligated to clean, decorate, alter, repair, or otherwise improve the rental, either before or after the execution of this lease, unless agreed to in writing as part of this Agreement.If a tenant moves in and notices something requires repair, I'll fix it.

Plus my wife decorates for Halloween, Christmas, New Years, St Patricks Day, etc.

And nobody has yet mentioned Lumber Liquidators, General Flooring, or Floor and Decor.

Would I probably just have to pay someone I personally trust to decorate the house for an Airbnb, or rental of a furnished house?

Have you seen a bump in bookings  with cosmetic exterior upgrades like updated siding, decorative lumber to front porch rails/bannisters, nice front door etc that would allow you to feature that photo in your listing?
