My thing is I dont think I will ever rent again. After owning a home without having a payment, you just cant see paying rent to someone else. Even if I have to make repairs on this home it makes more sense than to pay someone else for their property. I own this. Why would I move and line someone else's pockets? If I had to move, I would sell this one and get a smaller one and if I had to make a small payment for a couple of years, at least I was putting it towards something for me.
The new HVAC system we just put in was the best thing we did. Cut our utilities down dramatically. When it comes down to time for you to look for one, I can tell you what type I got.
