First Investment Property (SFH w/ questions!)

[Christopher Abele]

I am now under contract for my first property. 

We are purchasing with cash, will be renovating the property and, at some point in the future, will likely use it as a rental. (There will be some personal use first.)

Since there will be rental income associated with the property I want to ensure I'm setting myself up for success with taxes. 

Q: When do I ask for a W9?

We are having inspections completed today. The inspection was scheduled through a company but I'm curious as to whether I need a W9 from them since the inspection cost is $615.

For other services, such as the roof or driveway that the property needs, do I ask for a W9? Something different? Then... what do I do with them??
