As you may have read below, the Searles Way home you asked about is not a reliable rental. Single-family homes for rent can be a challenge to find in Petaluma, although there is a little more available on the east side of town. With the closure of State Farm's office in Rohnert Park, you might have better luck in the "M" or "L" sections. While there has been a good deal of new construction on the east side of Petaluma, homes have been selling slowly. You might be able to negotiate a lease with a developer - you might be able to persuade them that it is better to have a home occupied than vacant.
There are currently 12 three and four bedroom homes available in Petaluma ranging from $192,000. to $284,000. Depending on your finances, your monthly payments could be comparable to monthly rent.
Please let me know if I can help you in any way.
