I'd go ahead and work on trying to buy. That would make the most sense to me.
You will have to put your personal belongings somewhere so you'll be paying a hundred or more each month for storage rental. That will also be uninsured so if they get wet or destroyed in storage that will be an extra cost for your family.
Houses can't go down much more can they? It seems they have pretty much hit rock bottom price wise. I can only think if I had the opportunity to buy something I would just on it and take off running.
I would not do anything different if it wasn't going to make a HUGE HUGE difference in our qualifying criteria.
When we were looking for a home we had all kinds of things on our credit stuff. We had accounts with all kinds of places. We didn't owe them money but it showed the accounts. That meant that even though we didn't have anything charged we could pick up the phone the next day and order a bunch of stuff and owe them big bucks. So that effected our ability to qualify.
Hubby called each and every place and canceled our accounts. He paid off a credit card each month and canceled it. We didn't owe more than a couple hundred on any of them though.
He paid off everything he could one thing at a time. We qualified for double his yearly salary.
You would also have so much stress from the move, I can't imagine putting 3 kids with such an age range in one bedroom. If they are different genders the manager may not even consider renting to you.
There is no way a 17 year old, a 4 year old and a 3 year old can share a room T.. I think this idea is just not doable with the size of your family. 5 people in 4 rooms is just not a good thing. No matter how much you think it would work and be fun, it's just too stressful.
A friend of mine has 2 kids still at home. One boy and one girl. She is a neat freak to the max and always has an immaculate home. They lived in a nearby apartment and they were awesome renters. Always on time, no complaining, clean, no bugs or loud stuff. Kids were well behaved, etc...
They got evicted due to the kids all getting to school age. It was against their policies for different gender kids to live in the same bedroom. HUD won't allow it so many apartment complexes do the same standards.
I think focus on getting qualified and get a house as soon as you can. Once you move in it will be so much better.
