San Diego is the most HOA-dominated county in the state after Los Angeles. For history and operations of HOA as well as various horror stories, you can pretty much get them by searching internet. Here I’m just going to focus on things that you should pay attention when buying a home.
First, you need to know what HOA assessment covers for a particular home. Seller agent does not necessarily specify in entirety in a listing. I would suggest you contact HOA Management directly to get that information, asking what are included, such as water, trash pickup, exterior termite, HO-6 (a few HOAs cover this one, or before the close of escrow, as long as you mortgage, lender mandates you purchase HO-6 coverage). HOA fee runs roughly between $ 250 to $350 if water bill is included. An HOA fee of $ 350/month is considered above average. If you could find a home with low month HOA due below $150 and that home owners are responsible for their own water and HOA is only responsible for common area, it would be fantastic, though sometimes you don’t have much choice.
Then, you have to confirm the fee in the listing is really the one. Recently I saw a condo in Carmel Valley listed $ 200/month HOA due, but in reality it is $ 310. The seller agent wrote "Up to buyer and buyer agent to verify all information" to unload her job at ease. There is another situation that if the property was listed last year, you better call to find out if there is any change in the new year.
For those who are buying investment properties, it’s even more so crucial as this part of the costs is paid by home owner.
