I am not a very trusting person and therefore come up with lots of conspiracy theories with no help at all, so I am always afraid to buy something too pretty and then being at the mercy of my employers who I might not 100% trust or the banks, that can change payments, etc....therefore, I am with a pretty good score, myself. Even my husband who has had his identity stolen at least 5 times that we are aware of, somehow has a good score, but I am still considering your situation.
Okay, if I had a deadline of 3 months to fix as much of my problems as I could, I would have to get on the table with all my assets and liabilities and compare all of them and do at least a temporary overhall.
Needless to say, I would do many of the things listed on the topic of "What did you do to save $ today?" I would also consider getting everything I don't absolutely NEED, disconnected. I know that sounds extreme, but look at where you hope to be 3 months down the road. I think I would have to serve beans 2Xs a week and eat lots of leftovers. And I'd walk thru the house turning off switches and even unplugging things.
Honestly, I can save over 200 dollars a month, just by disconnecting the cable, land phone and internet service. With those things off, I can start making small payments on little bills and clean house real fast.
I don't know your exact complete situation, but would you be able to work? DH and I are both employed full time in really easy jobs, but I have a nursing career that I tap into sometimes and I can make more money doing that. Lately I feel I want to work less and make more, so I am taking steps toward that direction. In the meantime, I am not marking my extra deposits from nursing into my checking account....its all part of a game I am playing with myself. I go thru life playing little games with myself to fix everything.
If you only work @ home, can you make your homestead more profitable? Clean house and have a garage sale, kill extra roosters to save on feed, cover windows in the summer and such.
I know this is not what you looking for, but I would hope that in 3 months, you can fix all the issues you have against you. You might even take a temporary job, just so you can tap into your own credit history, while fixing DH's problems. Then you can always quit after you secure your family with a better deal.
