I would try and sell the house since it sounds like you can get out of it for little to no loss. But if you choose to do this it better be fast. This spring selling pop won’t last very long. IMHO
Rent until the lease is up on the tenants in the condo then move back into the condo. You are bleeding money every month holding on to both and also have double exposure to the price depreciation in the market.
Also, the condo is on a 30 year fixed more then likely recourse loan and underwater. You can’t get away from this money drain so get rid of what you can….the house.
You have to make the choice that is going to be better for your financial future. If you can take the emotion out of it I think you will come to realize that moving back into the condo is the best course financially by far.
