If you are looking at HRA the one thing really worth buying there is the dedicated ("Deluxe") 2BR unit, which is the 2BR portion of the 3BR lockoff.
There aren't many of them because I believe they are only located in Phase 2 (buildings 3-6) and the developer had to split a 3BR unit to make a sale. The square footage is about as large as the 1BR Premium which also translates to similar MFs (~$2100 for 2Br Deluxe vs $1900 for the Premium 1BR vs. $3200 for the 2BR lockoff). But it's still a 2BR/2BA and the layout is actually more convenient for a family with kids, without all that extra wasted space that you have in the lockoff and the kids being a long hike away. And it being a 2BR, it can also rent at 2BR prices which means $1500-$2000 over MFs for both Spring break and Summer season (this implies it should have a relatively high resale value as well). Since they eliminated rollaways, anyone with a party of 5+ now needs a 2BR unit, so rental demand for these has actually increased in the last 3-4 years.
The flipside is that whoever owns these is not in a hurry to sell them. Out of 48 HRA resales on RedWeek, just 1 is a 2BR Deluxe and it's for Silver season. If you're patient, it will eventually pop up but expect to pay a price premium which, imo, pays off over time.
Another good alternative is the 3BR lockoff which gives you the aforementioned 2BR Deluxe unit plus a corner studio that has an actual balcony. I think these are totally underpriced (Platinum for dirt cheap on RedWeek - no Gold available as of now) in the resale market because the MFs are like a 2BR lockoff but if you rent out the Studio side you still have the 2BR Deluxe and cover a substantial part of the MFs - you may even come out ahead versus just owning the Deluxe 2BR only, and also pay maybe less overall upfront, but it's a bit more hassle renting it even in years you use it.
