Most will likely stick to the technical limit of Sept 2021 when it ceased being a primary residence, but some may be comfortable going by the address on the 2021 return and others may explore a partial exclusion, depending on the reasons for your move abroad.If you'd like to read up on the technical rules, the IRS publication 523 gets into more detail than most people would like to know, but it does have some helpful tables and examples for different scenarios.

Thanks so much for a detailed response. 

Buy another property.I can assist with financing options on either route, let me know if you'd like more details!

Highlighting the STR revenue potential, especially in a prime location, could attract investors looking for both income and future appreciation.Steps to take:Prepare a detailed financial breakdown of the property's current performance and future projections.Include comparables in the area to show both STR potential and anticipated appreciation.Offer flexibility in the buyout terms (e.g., structuring it as an installment plan if needed).If you can’t find an individual investor, you might look for a property management company or real estate investor group that specializes in STRs.

Awesome and detailed reply.

I wont go into details about that place, but i wouldn't feel safe walking my dog there at all.

Jon Holdman thank you so much for the detail in your reply.
