These 2 comments are Bullshit. In San Diego the low and moderate income programs can be great depending on where you look. You can get a 400K place in Carmel valley at a fixed monthly payment of 1000 dollars or less. Take Airoso in Carmel Valley for instance. They have a low income component. Neighbors paid 600 plus for their place.
Are you going to experience appreciation. NO. The point of these programs are to provide you a place to live, build your credit, save money, then move on and make way for the next family.
