I think modulars are good in some areas and not so good in others. They are a cheaper substitute than a regular stick framed home. Alot will have to do with the quality of the company and the contractor you use to finish the installation process.
DO YOUR HOMEWORK...I say that to my 10 year old alot...Check out a list of references and ask them about any problem customers you can talk to. They will not want you to talk to them but insist so you can make an honest decision. Tell them you want to take the good with the bad and not encounter the same mistakes. If you are all on the same page from the start ...it ends up with a better product.. Also check out another company...there must be more than one around.
In this market today they will compete for your business. If they are not interested you would be better off without them, now you know what kind of service you will get up front.
Make it clear you want an open, honest line of communication at all times. If you need some help and can afford a Home Inspector, get one and you will not be sorry. They are there to work for only you, and they have seen more than you will. Check out
www.ashi.com for a qualified professional, It is the organization I belong to and we are only a professional organization, doing what we were trained to do. For a $500 dollar investment it saves you many times more in the long run, and less headaches since you have someone to explain the issues in a comfortable, easy to understand language. Not the double talk construction, that's not in the contract lingo.
I have installed about 12 modulars and am still not to impressed, but alot had to do with the quality of the products. You get what you pay for. The concept of modular is a good one, but the quality has to be there. So do your homework, it is a big expense.
I hate to ramble and go but...
Tell us how you make out. Everyone is curious.
