If you want to face the problem full on then you could simply contact your lender and ask them re the current status of things with your property. This would involve telling them where you are now etc etc and will probably start the ball rolling with a shortfall claim from them.(posted 7554 days ago)If you simply want to know if the house is up for sale why don't you contact the estate agent as a prospective buyer and have them mail the info to a friend? that way you'll know how much they're trying to sell the house for?
To safeguard your new life might not be that straightforward but not necessarily total doom and gloom. £15,000 is not a big salary and you have to live etc..there won't be much left after everything is accounted for ....they can't take what you don't have. They can't take your home as it's tied.
You don't need any stress with a baby on the way but only you can decide what approach to take...
I don't know if I've been any help....someone else might come up with something more constructive hopefully.
For the moment I would concentrate on looking after yourself and your baby before confronting them full on.
Take Care
