Sold our home recently but did this for 30 years.
There is the big stuff, like the roof, hot water heater, windows, furnace and HVAC, even floors like carpeting need to be addressed over time. If these things are aging out you might want to start a fund to replace. If they need it and you can, then try to do windows over time, same with doors inside and out. Look at your handrails, do they need work? Cabinets can get a really refreshed look with painting and a lot can be managed yourself with replacing door knobs and locks slowly over time. All
Overall don't be cheap with homeowners insurance. It is not worth the extra $35 a month savings if your roof collapses during a hurricane and insurance tells you that you get $2000 for a $25,000 job due to depreciation, get replacement cost value RCV not ACV where you only get the equity value remaining in your stuff. After hurricane Sandy I got a new roof for a $500 deductible and the neighbor got a $2k check, most of our neighbors got wrecked financially. Read your policy closely and know what the regional risks are, I knew someone who couldn't sell their home during a messy divorce because the insurance didn't cover sink holes and they couldn't afford to fix the one in their yard. yikes
Also, my utilities company offered insurance on my hot water heater, furnace and HVAC, plus washer and dryer. I think that I also found insurance for the water and sewer lines from my house to the street which, I discovered insurance doesn't cover as it only covers water that comes down not water that seeps up.. tricky and crafty.
Yes, these things nickel and dime you but the coverage I had meant not big surprises, I do not like financial shocks
