Investors & landlords

@Carl Thank you for the detailed response. 

How would you address the TurboTax question of Ownership?

 

Since my wife and I file jointly, designated owners are either her, me or jointly though legally neither one of us owns the property at this time.

 

What would be a good and accepted metric to divide common costs between the two buildings? The buildings which is available for personal use (100%) is also only occupied maybe 4-6 weeks per year as a vacation home. Would square footage be good or overall occupancy days of each section?

Thank you
