A $300,000 house with $10% down is a $270,000 mortgage.
$270,000 mortgage at 3.75% payment including principal, interest, taxes and insurance will equate to about $1,700 per month.
Assuming you not only have great credit but a monthly income that can support this mortgage and any other debts you may have, then there are homes "close by"
I suggest you meet with a Loan Officer and get a pre-approval letter to find out exactly what you can buy. Then call an Agent in your area. I strongly recommend Shannon Chang 626-319-8545. She is extremely knowledgeable, helpful and reliable.
