1031exchange or buy out ex-husband

[Jen Hoang]

I have a property I own with my ex-husband. It's in Houston, TX. I consider it an "A" property. Good Area, good school district. Tenant always pays on time and has a great job. The lease is coming up for renewal and my ex wants to 1031 the property or sell it. I don't want to sell it and I am not ready to do a 1031. Here are my questions:

Can we both 1031 into separate properties?

If I buy him out, how do I calculate the price? This property is worth ~250k, and we owe about ~$45k. 

Thanks in advance!
