Home ownership

Maybe I missed a thread similar to this, but that's ok. I have been in my home for 10 years now, and there are some things I wasn't prepared for or aware of as a homeowner. I am not scared to admit them if it helps someone else, and please share any stories you have about things you didn't know when owning a home for the first time, whether they be small or large, costly or not.

I will start with not knowing about changing the furnace filter until the a/c stopped working and I had to spend $300 on a new blower motor. Also, I knew nothing of cleaning my gutters, until one became clogged, held water, froze, and had the weight pull it down. Replacing the gutters was another $1000. I'm sure I'll think of other things but those are the 2 that stand out the most at the moment.

ITT we talk about home ownership, and things that aren't always obvious but need to be done to save on maintenance and repairs.
