We have a house on the smaller side and could really use an addition as we have 6 children in a 3 bedroom 1 bathroom home. We do not wish to sell our current home with the current economy and take a loss on equity. We own our home 100% free and clear. We could use more bedrooms and another bathroom. I noticed on craigslist there are a lot of repo'd double and singlewides for low prices. I was wondering about taking one of those repo'd trailers and attaching it to our current home and making it into an L shape. Course we would need to match the siding so we dont look like total rednecks but I just wondered if there was any reason NOT to do this sort of thing? I was thinking we could attach it for now and in 20 years when all of our kids (SHOULD) be gone, we can remove it and go back to the smaller home/dwelling which would work great. Our septic is large enough to already handle another bathroom. Our lot is wide enough to handle it within the offset restrictions or whatever it is called. the cost of a doublewide would be less than all the taxes/closing costs plus moving cost it would take to sell our home and move somewhere else. It seems the more frugal option. It would be cheaper than frame building an addition with an additional 2-3 bedrooms and bathroom. Anyways. Has anyone done this before? regret or grateful? anything I should keep in mind?
