@Nick Rivers If you've already taken courses and webinars, then the only thing that will help you become more proficient is by actually underwriting deals on a regular basis. 

Why do you want to try it? 

A professional manager can find qualified tenants who respect your home and handle day-to-day issues.

If the latter, simply give her the notice required (eg 30 or 60 days) that she needs to move. 

Whether it still makes sense will depend on how much you can defer vs. the basis.

We went to Delta Build's office on Monday, left our phone number and was told someone woukd get back to us within 2 days. 4 days have passed and no one has called us back.

@James Boreno You’ll likely owe taxes, but don’t forget to account for your adjusted cost basis, which factors in the original purchase price, depreciation over 10 years, and any capital improvements.

I actually am working with a buyer right now that wants me to manage his house hack.  

If they push back and demand a 60-day notice, then extend your notice to the full 60 days.Example: The lease expires in 40 days and the tenant demands a full 60-day notice.

I would start by listening to the podcasts, i especially liked the older ones!
