On seller side of seller financing

[Justin Ake]

I have an opportunity to sell one of my properties using seller financing. I hope someone can help me navigate the pros and cons. 
1. Can I still use this home’s equity for other deals while the buyer is paying it off in the next few years?

2. Can I still depreciate it until the buyer makes the final mortgage payment?

3. How are my taxes calculated and what years would I pay for the profit I make?

Never done this before so I’m flying blind and hoping someone has a few tips to help me figure this out. Thank you all!
