In The Tampa Bay Area local investor in the items inside the home/business but looking to get with the right people to build a team.

Hi does anyone have experience with providing direct STR stays (so not through Airbnb or VRBO) and charging, collecting, and remitting the local Chicago hotel tax?

You may be able to deduct mortgage interest and property taxes before the property is in service.

No matter where you settle upon, your idea to build really comes down to your goals.
