Partial VR ownership; house visit expense deductions

[Kris Barney]

Some friends and I are considering buying a VR together, which we plan to use a little and rent out the rest of the time. I believe if I owned the property outright, I could deduct 1-2 visits per year to the property to "check up on it". (1) Would I still be able to deduct these trip expenses as a partial owner? (2) if yes, is there a certain percent of the property I would need to own to be able to deduct the trip cost? (3) is there any type of co-ownership entity (LLC, S-corp, GP/LP) that would provide more preferential treatment for this? (4) if #1 is yes, what expenses of a family of 4 trip to the property for 7 days could I deduct? All 4 plane tickets, or just 1? Meals for all 4 ppl, or just me? Rental car? Lodging cost (assume me/partners agree we have to at least partially pay for our use when we use the co-owned property)?
