I prefer the term "Manufactured home," thank you very much! :p Even though I have a title for my house, because legally it's two trailers.
So, just for fun, we looked at "Modular/Manufactured" houses this weekend. I must say, I was impressed by the floorplans and value. 1800-2000 sq ft. There were some amazing master bedrooms with "retreats" and a huge master bath with rainfall showers, gigantic closets, tons of windows, sliding doors, new kitchens, etc etc etc for prices that bowled you over. Delivered, on "blocks" (no foundation) $90,000 to $110,000. Yeah, some of the furnishings were cheap (thin doors, thin drywall, fake wood baseboards), but wow.
Well, we were impressed enough that we bought one. :)
I would highly suggest getting a proper foundation poured, though. I think our foundation was $25k and that has a huge impact on the stability and longevity of the house. You can upgrade quite a few things if you want - we've got quartz counters (didn't care for granite), made a few changes in the master bathroom that leads to a comically huge toilet alcove with shelving, have a nice shower instead of a soaking tub and a phone booth shower, 20A circuits around, gas piping to anything that might use gas (even though we don't have gas to the site, we might put propane in some day), etc.
Any counsel or direction on simply buying a plot of land (acreage) for $60,000 and towing a trailer and utilities for $110K+$10K = $180,000 for a brand new "house"? Yeah, the house will likely depreciate. But it would probably depreciate less than the cost of the mortgage interest expenses, insurance, taxes, repair, etc on a big fancy house. Any issue having a house without a foundation? Other gotchas?
What utilities are you planning to run for $10k? Because unless you're in a subdivision, that's not going to cover power/water/sewer. Consider that you may need a well and septic system, which is $20k or more depending on your area. Plus power. We were able to put our house where a previous house had been, so we had well and power already onsite.
Look into a foundation for a double wide. I really, really think that you'll want that if you're going for 10+ years. The house is more stable, and you're a lot less likely to freeze your water piping up (which is a common way of burning down houses). It's been below zero, I don't have the insulation on the piping in our crawlspace, and things have been fine.
Another option to consider would be getting a little singlewide ($30k new, a lot less used), putting that on stands, and building your own house over time. You can save a ton of money that way.
I do realize, there are more expenses out there...like, for example, no garage. I guess I could have a TuffShed built for $5000 that would suit me. Anyone have experience?
I like my Tuff-Shed office, and we're planning to put up a carport and shed this next summer.
The cost savings on a manufactured over a site-built are a bit less when you work in things like a foundation, but we're still very, very happy with ours, and the time to build was insanely short compared to a site-built.
Ask around, though, and find out who makes the best homes in your area. The quality of different manufacturers varies, even if they all meet HUD standards, and it's worth paying a bit more for something nice.
For what it's worth, we plan to stay in ours the rest of our lives. :)
