Oh, here goes a few thousand for a nice bed/frame/mattress.
Oh, here goes a few thousand for a nice coach.
Oh, here goes a few thousand for new refrigerator/stove/freezer/dishwasher.
Oh, here goes a few thousand for a washer and dryer.

Oh, did I also mention need for "man equipment"... like toolshed stuff. Pressure washers are awesome! Leave blower if you want.
Hire a landscaping/gardner if you don't want to maintain your outside greenery. (mostly depends on if you have trees that drop leaves year round).
