+1 on 1, 2, & 4 re CC debt.
SOMETIMES new car can be reasonable buy IF bought at solid discount & held for several years. Price of good clean used cars is high now. Often the "savings" of a used car get eaten up in cost of fuel (usu worse mpg for similar newer car), higher medical pmts in auto insurance (fewer safety features), and cost of major repairs can turn old car into a money pit (e.g. just-1-more-repair syndrome). I generally buy new (going easy on the options!!) & hold for years. Bought my prev car new & held for 8yrs. Had similar (if not lower) overall outlays than certain relatives who dumped huge $$$ into repairs (tranny, engine, etc.). Current car (midsize 4cyl) is 4yrs old & my depreciation is less than what at least 2 diff relatives have put into their older used vehicles over that time- plus my gas savings of 27-28mpg vs their 15-17mpg (suburban driving).
+1 on DRIP stocks IF you stick with solid blue chips and monitor closely. Many once solid blue chips have ended up bust over the years. Most might be better off with mutual fund or ETF focused on consistent dividend payers, and reinvesting the dividends.
#3 is not for me. Real estate investment & management can be tough. Back in mid-80's I felt lucky to break even in sale of my 1st house. And trying to rent it in that market would have been a huge negative cash flow. Tried investing in a rental in 90's & again felt lucky to loose only a few $1,000's over 3yrs depsite putting in lots on time on it.
