Buying another property via 1031 exchange

[Julie J.]

1) I bought this home in prior to marriage and it has over 500k in equity. I am trying to sell it and buy another property via 1031 exchange, but will I owe taxes because my husband is not on the title?

Ex. 500k deduction is not allowed because I bought it as a single woman.

2) what happens if I buy another home as "second home" and sell above home afterwards, can I still sell it under 1031 exchange and receive tax benefits?

Ex. I am worried about second home is not being the same investment property.

Someone please answer!!!

Thank you in advance
