This is correct but remember when the community transitions all of the capital assets (pool, clubhouse, tennis courts, etc. are new so if the HOA begins to fund the reserve right off the bat it should be okay.
Sure; but they should identify what the upkeep/replacement costs will be and it's simple math to figure out how much you need to place in reserves over the lifespan of the item.
E.g. Fencing: 20-25 yr lifespan; $30,000 replacement cost (est w/ inflation); that means you need to be putting in around $1200-1500/yr to have that "fully funded" when its expected lifespan is reached.
And my HOA doesn't just randomly replace something because the "expected lifespan" is reached; if it's still serviceable, we'll delay fixes until it's really necessary and put the extra reserve funds toward other "buckets". It's not hard to work these things through, but it does require some time and effort to really lay out a clear and reasonably accurate plan. You're not going to hit every item on the nose for costs and when it needs replacing, but if you are close, it is very easy to shift reserve budgets around from other things a long way off from repairing, and you have ample time to recover those costs if you end up overbudget.
The place where HOAs run into problems is NOT funding things that are significant cost items. And not realizing that until they're basically at the end of usable life, and either an amenity is shut down, or you have something (like roofs for condo complexes) which can/will result in substantially higher risk of damage to individual owner properties.
Once people learn how this works, and IMPLEMENT a reserve plan, it's really quite easy to maintain one; the problem is they never actually do the upfront work and end up in trouble.
