Sorry but your question is unclear. If you are inquiring if these factors are a concern when a buyer is looking at a home on a Zero lot compared to a standard lot 60 X100.
Both have set backs. However the privacy issue favors the standard lot. Developers found that they could provide a savings to those that did not require a full size lot. When you are pricing a home to sell using the comparison of the size of the lot, pool, sqft, privacy walls do count. Adjustments in price are made where one property is inferior to an other.
