I am single, aged 51, and I live in a condo because I didn't want to have to worry about mowing the lawn, etc. I also like the added security of living a building with a locked door, neighbors who know each other, an onsite maintance person to be here to sign for any packages delivered and let repairmen etc. in and out. Finally, I love the fact that I could get "more home for the money" with a condo. I could afford a condo on the water with a great view ... but could never have afforded a house in such a nice location.
However ... the very big down side is that the monthly maintanence fee can be very high and I have to live with the decisions made by the condo association as a whole rather than have the freedom to make all the decisions myself. It's nice to have other people to share the responsibility for maintaining the building, the parking lot, etc. ... but it doesn't come free. I may save on having to pay someone to mow the lawn for me or shovel the snow or repair the front steps ... but I do pay monthly fees to cover the costs of those things ... and I have to live with (and pay for) the decisions of the group which may not be in sync with my preferences. I've served on my condo association board of directors, and believe me, it can get very political as not everyone has the same opinion about how much money to spend on making the condo community "luxurious" vs "basic."
Also, don't forget that major repairs to the building or updates may be needed and the owners may have to chip in additional money to pay for those things -- just like you would have to pay for fixing your roof or water sealing a deck, etc. if you owned a single-family home. Some people forget to budget for these sorts of things, assuming that their monthly maintanence fee will always cover everything. It usually covers the small stuff, but not always the major repairs or replacement.
Before I bought my condo 8 years ago, I bought a few books on the subject and read up the whole condo vs house decision. I went to Amazon
.com and easily found a whole bunch of relevant books on the topic (with titles such as "How to Buy a Condo". The books really helped me a lot and walked me through the decision. I also used a "buyers agent" as realator -- an agent that represented me and me alone in the transaction and who did not represent the seller.
