Well, I survived, and STBX seems to have recovered from his hissy fit earlier. Put on my pleasant face and actually wasn't very hard to act pleasant around the realtor, who was really nice. It sounds like her assessment was about the same as the guy from last week who put us at a price that's too low for me to handle.
I did ask about renting and her agency handles it. She suggested it wouldn't be hard to get more than our current mortgage amount in rent but said she would talk to her partners who handle rentals to see what they thought. STBX seemed receptive to the idea. Heck - if we could make money off of this for a few years, that's good news for me. Then maybe I could use the extra rent to pay down the mortgage faster to an amount I could refinance by myself?.... options are good.
