Did you know that the city of Corona offers a buyer assistance program that will loan you up to $75k at ZERO percent interest! It's a no interest 2nd. They also offer up to $5k in closing costs. A sweet deal if you can get it.
I don't think many people are aware of this perk. There are of course restrictions but overall the program is pretty straight forward. The thing that may exclude most people are the income restrictions. They are pretty low. For a family of 4 you must make between $53k and $74k per year. It does not say if that's gross, net, adjusted or what (i'd guess that's gross pay).
