it sucks when everything goes at once. But overall - I would choose home ownership over renting ANY DAY!!!
My neighbor is renting - her landlord has taken TWO YEARS to fix the floors from a leak. She's moving out at the end of this month as the landlord doesn't want to put money into the house.
Nothing in our home is "easy" - what some would say is a "five minute" project? Turns into an all day thing!! no kidding - the ceiling fan in the master bedroom? Supposed to take about 15 minutes according to the directions - and in someone else's home - yep! Ours? Nope!! All freaking day! Wires, etc. urgh!!
Windows? I would replace them with more energy efficient ones. Yes, it's a big cost, however, so worth it in the long run!!!
We've lived here for 16 years. We have replaced the roof ($5K), replaced the windows ($7,500), replaced the garbage disposal ($250), replaced the garage door ($1500), painted the house (outside) $3K, replaced the family room floor (got a total steal on this project!!) $2,300!!!! Replaced the water heater ($400 as my husband did it himself). This has been spread over time.
I could pull out our books on the house and tell you - but really - each home and location is different.
I would replace all carpeting with hardwood floors - that's me. Next up is the kitchen - hopefully this summer - replace the floor, new refrigerator, dishwasher and add a pantry, above stove microwave and granite counter tops).
