Investing in Townhouse

[Logan Wright]

There’s a townhouse that just came up for sale in my area that I really like. It’s move in ready and all the numbers check out.
my question is about townhomes in general. Do they make good long term investments? Do they increase in value similar to a single family home? 
mare they any drawbacks you can think of that I should know about in the long term? 

Thanks!
