What are the differences between condo vs condo townhouses other than the obvious like the fact that you have more privacy in townhouses. Benefits / drawbacks of them? And other things that you guys have in mind when deciding between the 2 choices.
First off please read the thread about why condo's suck as investments and the reasons why.
Second I actually like condo townhouses vs freehold townhouses or attached houses of any kind.

The reason why is uniformity of appearance. The problem with the freehold and attached houses is that every owner has the option of renovating their home as they like. Problem is that after 20 years every house has a different roof color and different door styles and to my eye it looks like crap. God forbid that you buy the semi next to the guy who painted his house bright pink and has a huge statue of the Virgin Mary in his front yard. (this is a house I have seen)
Condo townhouses have rules like you must have XX model of light by your front door and they are all the same and that's that. If they don't make said model anymore they change them all to another approved model and again all the houses have a uniform appearance.
Also you get economies of scale, for instance it cost less to have the same landscaper come out and mow 40 lawns than it does to have 40 different landscapers come out at 40 different times to mow. Or it should anyways.
One advantage to condominiums is that you generally have a lot of amenities. Pools, work out rooms etc. If you use them that is a real bonus. If you don't use them then it really sucks because you pay for them. So really examine if you are going to use them or if you just want them in case because most people in fact do not use them. Also it may be cheaper and more enjoyable to go to the Y.
Ok condo townhouses have rules and that's a good thing except when you decide to plant pink flowers instead of the approved red or you get a notice asking you to take off your door wreath. In every complex there seems to be a retired crone who's sole purpose in life is to ensure that you follow the rules. So that can be very irritating.
In any case if you want the real dirt on the place ditch your real estate agent go back and ask around what it's like to live there. People will tell you if it's a dive or a nice place to live. Stick to smaller complexes and no extra amenities to reduce maintenance fees.
