A city, county, or city and county that receives a grant from the BEGIN Fund shall use the proceeds from the grant for downpayment assistance to a prospective first-time home buyer who enters into an agreement to purchase a newly constructed home, or a newly erected manufactured home placed on a permanent foundation, with the sponsor or developer of the identified newly constructed project within this city, county, or city and county provided the first-time home buyer qualifies as a person or family of low- or moderate-income, as defined in Section 50093. Any

residence assisted with downpayment financing provided by the BEGIN Fund shall be continuously occupied by the home buyer as his or her principal residence for at least five years following recordation of the deed of trust. If the home buyer fails to meet this condition, the loan amount shall become immediately due and payable to the grantee city, county, or city and county.
