P R Ranjit, I work with modular homes on the west coast. In general shipping can be a large cost so most builders stick with companies that build in their area. Therefore I am not familiar with companies in your area. These homes are built to the same codes as stick built / on site built homes. The only difference is one is built in a manufacturing facility and delivered to the site to be connected to a foundation. Once in place they are the same thing as stick built. They can in general be built faster, built with high tech tools not normally found on site, kept out of wet weather, and with features to your specification and budget. So for a similar house built to the same codes, they will go up and down just like the neighbors site built home. Obviously if the neighbors home has a better view, larger rooms, crown molding, real hard wood floors, etc it will be more desirable. those are all things you can put in your modular home too and if your neighbors don't have them then your home will be more valuable. You can get carried away with extras, so be sure to compare with a local builder what their costs would be. Also check the shipping rates as that can add up on a bigger home if the house is coming a great distance.
