Quote from @Garrett Brown: I have had maybe 2 to 3 guests trying to check in early or "just go by and check the place out," which always scared me to give the information that far in advance.

These issues should have been ironed out in advance.  

Thank you in advance for any advice! 

If the proper reports and documentation are not completed, you run the risk of failing an IRS audit and the cost segregation not being honored.

This is my first deal of this kind and I want to make sure I am considering everything.Thanks in advance!

Did you also include financials/ POF for the down payment/ credit report/ info on yourself such as your experience level operating rentals, to give the seller more peace of mind to lend to you?

@Hoai Nguyen suggest modifying your current lease to cover multi-family setup.Parking, shared access, police report required for landlord to get involved in disputes, etc.

Our problem is, with our pet-friendly cabins, guests are bringing their pets and not reporting (nor paying) for them.

Thanks in advance. 

Lien waivers are also helpful tools and always require them as you advance through stages of the project.
