Also make estimates (in years) as to when something is going to need replacing (roof, outside paint, carpets, hot water heater, kitchen repairs, fencing, etc.) and start that bank account ASAP taking into account (use 5%) inflation. This way you'll have the cash at hand to make the changes when needed.
Your loan broker probably didn't tell you but your loan will be sold shortly, expect it within two months.
Now that you have the space, the big sales come annually on items that you'll use...paper products (paper towel, toilet products, Tampax, etc). Remember there are mice in this world, so put out traps and poisons.
If you jump in and buy a whole years supply when the annual price is lowest, generally pre-Spring, you save a couple of hundred dollars on that single purchase. Do the same for home cleaning products and personal products, ie. Windex, shampoos, laundry soaps, anti deodorants, toothpastes, etc.
Instead of looking for new everything, consider used lawnmowers, garden tools, lawn furniture, etc. You can save big dollars buying the used ones that still have a few years left on them. I do this just because the first time you use that new $600 lawnmower it is "used". For a tool that is lucky to see two hours use a month, I can't see spending a lot of money on it.
Become a weasel on food prices. A good used freezer that someone is selling because of a forced move is something to be on the look out for. After you get one, when you see chicken down real low, buy thirty pounds of it. The same for steaks and hamburgers or whatever is a large item in your diet.
Use every coupon that comes your way. Oil changes, haircuts, lawn fertilizer, you name it. Keep track of these savings and you'll find they will pay for the replace/repair bank account payments.
Ask your new neighbors what lawn fertilizers to buy...they've already bought the wrong ones and had lousy lawns before you arrived. The same goes for sprinkler settings. They'll know where the best hardware and plants stores are.
Most of all enjoy your new independence from landlords. Have a Merry Christmas and a Happy New Year.
