I still think you should get a house. If you're in escrow, your current landlord will probably let you go month to month till you're escrow closes.

If you want to later get a divorce you can decide to stay and maybe rent a room to pay on a second TD your husband would need to carry to get his 1/2 of house.

I've been a Real Estate Broker for over 35 years. In CA. But many things are the same for all of the states.

It would be better for your children. You could little by little make improvements to increase the value.
