J., I hardly know where to start. I see where Kemp has a population of less than 1200 people according to the 2000 census so you don't have much competition in the grocery stores. It may pay you to shop the major chains in Dallas.
In my opinion, the most expensive, low quality furniture comes from Rent-a Center or places like it. They take advantage of people with little knowledge of quality and value. They sucker you in by telling you its only $X a month. The next thing you know, your entire check is going for stuff that looks good on the show room, but nowhere else, especially after its been there a month or two. Send EVERYTHING you can back to Rent-a-Center so you have some money that isn't committed. If your bed is from Rent A Center, go into Dallas to the closest Goodwill or Salvation Army or something similar and buy a matress and box springs so you will have something to sleep on. Get four cinder blocks and four 2 by 6's and place your mattress and box springs on the cinder blocks so your bed is not on the floor. Go to your closest grocery store, and that may be Dallas also, and get enough banana boxes to put your clothes in so when they come to get your chest of drawers they won't take your clothes or just empty the drawers out on the floor. My wife and I bought our first "bed" from a garage sale for $25. It was an uncomfortable, ugly, sleeper sofa. We paid cash. We bought a table and two chairs for $10, cash. I realize this was 37 years ago, but the idea is we lived poor because we were poor. I have been to garage sales within the last year where I have seen a table and 4 chairs for $40, a dresser for $10, a couch for $50, a TV for $25. I bought a queen sized mattress and box springs for $35 because they were moving and didn't want to take it with them. Dallas has a lot of TV channels so you don't need cable. Most young married people are used to living in their parents home. And want RIGHT NOW what it took their parents 20+ years to accumulate. Pay as you go. Start a garden. Kemp is in the country. Buy 6 or so chickens for their eggs. Let them roam the yard and lock them up at night and let them out in the day time. This will keep you from feeding chickens to the local foxes, raccoons, possums, etc. By letting them roam, you get high quality eggs, that are much better than you can buy in the store and the chickens will fend for themselves. Give them left overs from the table and garden.
You said you bought your truck from a lot where you make payments at the lot. I know from examining the books (financial statements) at dealers that dealers usually make 75% to 100%+ profit on a car or truck they sell on a Tote-the-Note lot. They usually sell the same truck or car two or three times and make 100% each time. (They sell it. Repo it for non payment and sell it again.) Most of the time, the down payment and first payment covers the dealer's entire cost of the vehicle. Pay the truck off and NEVER go to a tote the note lot again. Take the note you are paying on the truck and, after the truck is paid off, deposit the payment for the next two or three years into a savings account. When the truck dies/quits running, take the money you deposited and use it for the down payment on the next one. Don't go to a Tote-the-Note lot to find your next vehicle.
Start by making a list of all your debts, how much interest they are charging you and how much you owe. Find the bill with the smallest balance, with the highest interest rate, and pay it off first. Then do that with the second lowest balance with the highest interest rate and so on.
You can save a lot on food. Quit buying ready made meals. If you want fried chicken, cook it yourself, don't buy banquet, or Church's or KFC. If you don't know how, ask. Most good cooks will be glad to show someone that is interested. Don't buy boneless skinnless chicken breasts. Buy chicken leg 1/4's. BTW, Chicken breasts selling for $.99 lb are boneless skinless chicken breasts for $1.41 per pound with the bone removed and the skin off. (I went to a butcher and he cut the breast meat out and we weighed the boneless skinless part.)
I know this is a lot to take in. I was a finance major in college. I've done financial councelling for my church. If you have questions, e-mail me.
As a rule of thumb, you should be saving 10% of your gross income. Gross income is your income before taxes. My wife and I did that and we paid off our cars and home and learned to live on much less than we made. Until my kids left for college, I was eligible for some sort of public assistance my entire working life and NEVER took it. We earned our own way and paid our own way. We taught our kids to so too.
Good luck to you and yours.
