Th u uhite-lead paintetl homes at Aew Salem. 1 White lead paint in creases the salability of 3 small homes by making the house decoration beautiful and lasting first and lasting impression, and these two points are often the determining factors in either the sale of a home or in a prospective client's selection of a builder or architect. The exteriors of small development homes are very similar to window displays in stores. If attractive, prospective customers are drawn in. and the operator has a better chance to demonstrate in detail the complete home. On the other hand if inferior quality paint or unskilled application has gone into the painting, the attractiveness of the development will suffer and clients will not be fa vorable impressed or wish to investi gate the project more closely. In this respect one point must be remembered. It is not enough that the exterior paint decoration be attractive when first applied. It must remain so. In anv development, the houses first erected have usually been standing for some time before the whole project is completed. Although, when first painted, the original few homes may have been attractive, if the paint used is not durable this beauty will fade rapidly and the sale of later homes must suffer due to the uninviting ap pearance of those first constructed. \\ illiams-HarterCorporation.build ers of New Salem have fully realized this important part that paint plavs in successful development building.
