Hello my name is Paul Bouchard and have been a builder since early 1980s, and a modular builder since 1990. And first licensed to sell real estate since 1985, and presently am still Lisenced and selling as well as helping people but develop land and develop my lots. In all these efforts I have developed and built stick built , modular and panelized. And if the modulars are built with proper specifications they are being appraised for newly built or resale at the same values as others homes of the same spesicication. Of course the exceptions are when they are built with poor spesicication (roof sheathing, floor sheathing etc ) or if the company builds in a less than exceptable building methods (starting with poor base materials and building methods) or if a home has been neglected and it resale value reflects the condition. Actually most good manufacturers build their homes much much stronger to be able to sustain the transportation. Also there are differences in how one manufurer build versus another so it pays to do a factory tours to see which manufacturer you like. So feel free to develop your home with a modular , BUT if it is a quality home you are likely to save no more than 5% to 10% if all goes well
