Lawn mowing costs for row-houses in Baltimore, MD?

[Adam Grumet]

I own several properties in the Baltimore, MD area. Mostly small SFH or 2-unit row-houses. All the lawns (both front and back) are small and modest (i.e. no flower beds, or complicated plantings - just mediocre lawn to mow). I've been paying $35 per mow for bi-weekly service. This seems high, and has turned into quite the capital cost.

I am curious to know what others have been paying for simple lawn mowing, especially in the Baltimore area, but any information is welcome.  Also, if there are any landscapers out there who can offer their services at a better rate, I am all ears.

Thanks, 

Adam
