I agree the question revolves around what you want your life to look like. I buy and hold. I live in an urban multifamily that throws off ~40k in income, besides living free in a place that would rent for $3000+. Including 2 other properties I have 12 rentals. So I spend time at maintenance, but it's not a full time gig.
The way I look at these investments: if you buy a place for 25% down that just pays it's own way over a 15 yr mortgage (debt service, maintenance, everything) at year 15 you've made 9.4% on your money even if the property didn't appreciate at all and the rents didn't go up. 9.4% is very high for relatively low risk return, Bernie Madoff only promised 10%! However we pay for that with high participation. But rents always go up, and values usually do too, values here are about back up to late 2005 levels according to Zillow.
I don't view RE as a living, or a fast money scam like some newbys seem to, but as a secure retirement, since my other freelance business does very little for me in that way.
