Need an Investor for Richmond, El Sobrante Home (richmond / point / annex)

We are retired and have low income, some money and great credit.
Our rent is skyrocketing so it makes sense to buy a home.
Our son has bad credit, no savings and good income.
We are looking for an investor who would like to part own a home with us in Richmond or El Sobrante (El Cerrito, etc too expensive) area.
