If you see a lock box on the door to your rental (when you live downstairs), why wouldn't you call the tenant and question them?

So this really isn't a 1031 question so much of a trigger of deemed sale question.  

And personally I cannot pull the trigger on a turnkey operator.

For example, any foreclosure of a home equity loan must be through judicial proceedings (court), and cannot proceed as a private foreclosure.All home equity loans are non-recourse loans, meaning that if the lender does not recover the full amount owed by the borrower through the foreclosure process, the borrower has no personal liability for the loan and cannot be sued for any remaining balance owed.Back to topConsiderations When Taking Out a Home Equity LoanHome equity loans can be a useful tool to allow a homeowner to obtain funds that are otherwise locked up in their home.

I would like to learn more before I pull the trigger in the next 6 months. 

Send them the lock code in pre-check-in instructions and at time of check-in (because not everyone reads the full message first time round), and automate a "how are you liking the place?"

Any one of these could and regularly trigger a special assessment.

One more tip – people remember stories that trigger their emotions.

Our current mortgage is a 30 year conventional locked in at 2.75% and the monthly payment is roughly $2000 ($1000/person).

Tenant also claims they lost the key so I quoted her to change the locks because I will not pay for the locks if they lost key.
