MOST IMPORTANT!!!!!
Be wary of low prices. Condo construction plays a HUGE part of whether or not you will be happy with it. Talk to the neighbors. Ask about noise. Then talk to the developer if possible. Ask about noise. Then talk to the BBB. See if the developer has any complaints. Look up the area on the Real Estate system. San Diego has to have one. Talk to the neighbors again and ASK ABOUT NOISE. Also find out about HOA dues and fees and have there been any outrageous assessments. You need to ask the treasurer or President if the reserve funds are there to cover large repairs. You don't want to pay $100/mo only to find out there's a $500 assessment each year because the dues don't cover the expenses. Find out what you can and can't do to your condo. Many only allow paint and flooring changes with nothing being changed on the exterior. HOAs are both really good and really bad. There is rarely an inbetween with condos. And ask the HOA staff if there have been any issues with noise.
If there are ammenities (pool, workout room, etc) how much of this is being paid by the HOA dues? Is there a yearly fee? People forget about all the hidden costs of condos. Power? Gas? water? Trash? what is paid by the HOA and what is paid by the homeowner?
