This is you are the reporting taxpayer on both ends of the transactions. 

Sorry for the late reply @Linda Weygant, I missed the alert and didn't think I got any replies...Great response, and that's pretty much how I set things up w/my CPA.  

Some red flags alerted me because I have seen this scam a ton recently.

For purposes of this paragraph (e)(3), an activity involving the use of tangible property is not a rental activity for a taxable year if for such taxable year—(A) The average period of customer use for such property is seven days or less;(B) The average period of customer use for such property is 30 days or less, and significant personal services (within the meaning of paragraph (e)(3)(iv) of this section) are provided by or on behalf of the owner of the property in connection with making the property available for use by customers;(C) Extraordinary personal services (within the meaning of paragraph (e)(3)(v) of this section) are provided by or on behalf of the owner of the property in connection with making such property available for use by customers (without regard to the average period of customer use);(D) The rental of such property is treated as incidental to a nonrental activity of the taxpayer under paragraph (e)(3)(vi) of this section;(E) The taxpayer customarily makes the property available during defined business hours for nonexclusive use by various customers; or(F) The provision of the property for use in an activity conducted by a partnership, S corporation, or joint venture in which the taxpayer owns an interest is not a rental activity under paragraph (e)(3)(vii) of this section.

Sounds like they weren't or they would have caught the non-compliant work and stopped the Contractor and alerted you.

Where it gets complex is combining properties with different ownership structures.A good rule of thumb is the what needs to be the same is the end TAXPAYER, so for example, we just did a 1031 where 2 separate LLCs (Single-member and thus disregarded entities from a tax standpoint) both owned by the same parent LLC  sold (relinquished) properties and a 3rd and different Single Member LLC (also owned by the same parent LLC) bought the replacement property.   

As above, keep a record, alert the police and keep them informed.

I expect them to be done on their timeline, for the price they said it would be, and if something changes they are to alert me right away.
