Can you split your property in Poway?

Sell it direct and there's no realtor commission: In a direct sale without a homeowner listing agent, no listing-agent commission is charged to the homeowner. Escrow, title, lender, tax, permitting, and other expenses may still apply. The written agreement specifies which party pays each cost. See how selling part of your backyard works.
