The net value of any piece of realty, for purposes of posting bail, shall be determined by multiplying the assessed valuation of said property by the applicable county factor, and subtracting therefrom any mortgages, liens, or encumbrances. Alternatively, or if such calculation shall yield a value insufficient for the posting of bail, the surety may present a verified appraisal report from a licensed real estate broker doing business in the county where the realty is located, establishing a higher valuation for the realty. Such appraisal may be substituted for the multiple of assessed valuation.
