Your offer was not valid, it is not legal for a CA real estate agent to sell real estate in NJ, they have to have a NJ license to do that.
You can't get the tax credit no matter what you do, you had to be under contract by 4/30, obviously that did not happen.
Quick answers are not necessarily correct answers.
Veh C 23152 is not felony DUI. Felony DUI requires injury to somebody other than the driver. (Veh. Code sec. 23153.) If this is a 23152, and he has no prior in the past 10 years, the maximum sentence is 6 months in jail. The maximum sentence for felony DUI is three years in prison. (Veh C sec. 23554.)
The maximum sentence for felony evading, which is the statute you cited (Veh C sec. 2800.2) is three years. If this is a misdemeanor DUI and a felony evading, the maximum would be three years in prison and six months in jail. If it is a felony DUI, because of the way consecutive sentences are calculated in California, the total maximum sentence would be four years, four months, in prison.
Nothing even close to 15 years could be imposed in this case, and the more likely outcome would be probation with some time in county jail.
