I am sorry about the fire. I can't imagine the devestation you felt.
My modular home (ranch) was installed almost 3 years ago. I replaced the house I grew up in. I love it! I had an amazing house company and contractors that I worked with. It is a lot quicker than a "stick built" house and better built too. I was "homeless" for less than two months, including the 3 weeks it took the electric company to disconnect the power from the old house. Because the house is built in a factory, it is built within a 1/16" of being perfectly square.
Some people confuse modular homes with pre-fabs or mobile homes. My house was built in a factory in two pieces, front and back. Other than wider doorways along the "marriage" wall, you cannot tell that it is a modular. I had all the options I would have had if I had the house built completely on-site. I have a full basement too.
Research the house company and the contractors that will be building and installing the house. Fortunately, mine came with unbelieveable recommendations and they lived up to them.
Good luck! And let me know if you have any questions. I love telling people about my new home.
