HOA is like $350ish/month. Special assessment is a big chunk. Like over 10k, but if you look at where these prices are going it seems totally worth it. They are definitley not fucking around with the reno work. New sheathing, insulation, and siding. All new trim work. New windows. Even new structure under the sheathing in alot of instances.
For what it's worth, my buddy who just moved into a pimped out 2bd/2ba loft unit will be paying much less with mortgage + HOA at Hill than he was renting in the meadow at a place with propane heat (which we all know heats nice but its like burning piles of cash in Big Sky).
