Sentence Correction

Any real estate professional will tell you that the value of a parcel of a land is most directly affected by How extensively it has been developedand how close it is to a major business,

Both the bolded part of the sentecnes are parallel right ! but "how" is repeated in both the sentences isnt it redundant ? cant we remove 'how" after "and" ... please elucidate


Thanks in advance
