Shovel Ready Permitted Units/Lots - value add factors include expanding paper lot entitlement to reach a stage where the units/lots are shovel ready and can be sold to a 3rd party developer that will build the horizontal (site) improvements and sell the improved site to a vertical developer or both.3.

Some homes I've put in basic Ikea type drapes along living room windows, some of the homes I've put in the faux wood 2" blinds, some the general Home Depot horizontal blinds.

We typically use 3/4" furring strips applied vertically (for horizontal siding) to provide an air space behind the siding.
