BIL and SIL live in an 8-unit HOA, which operates as a subset of a few hundred mixed units with pools, tennis courts, golf course, water front docks, and a restaurant. Their experience has not been good. In a group this small, you are essentially on the HOA board, with constant communications. There is always something going on, and we were often read aloud the emails form “Jane” who seems to work this full time. This complicates their involvement, since they are only at their unit 5 months out of the year, so they can’t always see or be there for discussions. Whether it is roof, stucco repair, lawn maintenance, or other items, there is always something to discuss in group-think. Keep in mind most of these people are successful, Type A personalities, so it can be very dynamic. They were hit by two hurricanes, which introduces complexities of what is covered by HOA, personal insurance, or not at all. Due in part to the HOA, they plan on selling their unit soon after only a few years of ownership.
MIL and FIL lived in an 80-unit condo on the beach in Florida. HOA was a constant issue for them. Decisions were made on large assessments such as hurricane doors, balcony repairs, and various other items. It was not unusual to be assessed additional $10,000 for these items, above and beyond their $500 month fee, since there was little reserve in the budget.
We lived in a 300-unit townhome community for 4 years. The HOA was tightly run by a strong board who reported to an outside management company that ran the numbers. It had a healthy reserve, even during the real estate bubble. There was never any impact to us, and we were always happy with the maintenance and service, all for $135 per month. There were no increases, no special assessments, and not idiots to deal with.
So our experience is that more units is better, but it really depends on the individuals and the management structure and process for decisions.
Right now we are in a single family home in a neighborhood in Florida. No HOA, and it’s the best situation in our opinion. Good luck in your decision
