I live in a condo complex - the style is comprised of townhomes - and we get an increase every few years or so, based on the projected budget for the coming year, and also based on keeping a healthy balance for future maintenance projects.
Ask what the fees have been over the past 5 years to see how many increases there have been.
Make sure any complex you are considering is financially sound, and ask if there have been , or currently are, any special assessments (these cover larger than usual updates or repairs).
Know that older complexes will/may be dealing with upgrades that younger complexes might not need as yet.
Ask enough questions - get the answers - so you won't be in for any unexpected surprises!
Is it because you like the Security and easy maintenance?
Or is it because you think you are getting a lower price, a better deal?
When you factor in the HOA, their management impact, and the Fee; are you really saving anything.
The Agreement that you will sign with the HOA gives them dictatorial power over your living conditions, and, yes, they can raise the HOA fee every year, if they choose.
