Preapproved buyer wants a Residential Income Property In Hayward, Castro Valley, San Lorenzo, or San Leandro

Any current homeowners or agents out there trying to sell their investment property in the Hayward, Castro Valley, San Lorenzo, or San Leandro areas? I have a buyer that's preapproved up to $350,000 and is looking to close like yesterday. They would like each unit two have at least 2 or more bedrooms. A duplex, triplex, quadruplex, 2 homes on one lot will absolutely work for them. The best time for my client to view some homes are usually the weekend or weekdays after 2:30 pm.
