.: Quote from @Sebastian Butler: Can you sub to an existing property you own that is currently owner financed?

Upsells include concierge services, butlers, parking, local tour guides and activities (affiliate partnerships), renting different parts of your property at the same time to different clients, romance packages, spa packages, up charging for high end amenities, massage/wellness packages and affiliate partnerships. 

@Angelo CortezMost STRs report income and expenses on an IRS Schedule E (not Schedule C) unless your STR is offering "substantial services"-> for example, concierge services or a butler to guests. 

 @Eric Lowder since you didn't place the "property in service" (e.g. make it ready and available to rent) until Jan 2024 you'll report the income and expenses on Schedule E in the 2024 tax year.In rare cases, that short-term rental income will be reported on Schedule C, but this is only if the rental offers "substantial service" that includes things like concierge services or a butler. ...

Since you placed the property in service in 2024 you'll include it in the 2024 tax year on IRS Schedule E (in rare cases it would be included on Schedule C, but you need to have "Substantial Service" like concierge or butler for guests as an example).Startup costs are an option in 2023 tax year but this is limited to $5,000....

Forgot to mention - Mike Butler wrote a great book Landlording on Autopilot.

@William Butler, is the property a duplex or two separate town homes with their own individual parcel numbers and separate tax bills?
