When I rented a townhome, they would not do anything with the space inside our fence, but they would maintain the part outside it....only that didn't seem to include clearing the parking lot from snow. If you wanted to fence in your yard, you had to choose only their fencing options, and use their approved contractors.They didn't like our fall decorations and issued us a nasty gram. And when it was time to repaint, they did everyone and you had 4 color combinations to choose from. I don't know the monthly fees because we paid the owners and they paid all that for us.
My SIL was harassed repeatedly by her old HOA because of things that she was never told about (as a renter) or things she wasn't given a chance to correct. For example, her son is a mechanic and changed a tire in front of their house. Someone took it on themselves to report her for doing car repairs on the property and she had to argue the fine she was presented. Or they said her flower garden wasn't properly maintained and threatened to remove it and have her pay for it, when she had JUST moved in.
I've read some horror stories like "no car more than 4 yrs old". So decide what is a true benefit to you and what's an annoyance and what's uncool.
The county has their own rules about things like junk in the yard or tall grass. But some HOAs take it upon themselves to babysit people to their standards. I like being able to chose the color of my home and based on the prices around here, our neighborhood has stayed stable or above average without an HOA.
