Don't listen to any of these idiots on this page. They have no clue what they are talking about.
To lift a house, it's all about the dimensions. Doesn't matter how heavy it is or anything. The second thing is the basement and where the lift equipment needs to lift from. Concrete basement, means that it prolly will crack with the weight of the house.
To life a basement it should only cost 10-15K Depends on the size, yours will be anywhere from 12-15K. That is lifting and excavating to make a new basement or doing any extra work with moving the dirt or debris under the house out, to build the new foundation. Not the issues
The issue if finding a good masonry contractor who can work with your foundation. When it is lifted, if they need to post new wood planks, that will cost you $2,000-$5,000. That is where your house will attach to the actual new foundation, concrete.
The actual process of putting up the wall is what gets tricky. With whatever drains you chose, concrete, rocks, concrete flood finishing the walls with drywall etc. It can run you up to 10-20K. Remember you might need to run new elec, plumbing and such. If some of it needs to be fixed, might as well push in the extra cash to get it all done and not have to worry about anything for a LONG ASS TIME. lol
But the return of all this, refinance the house, will be great. Say this house was worth 100K. Doing the new basement, plumbing, elec, foundation. Will bring this house 100% above the rate. You're refinance will get you @80% $80,000 in pocket. which pays off the bills that you had to do the work and 30K extra to pay back towards the house.
****, might as well take that extra cash and put in new windows, insulation, drywall, paint, bathroom, kitchen supplies. Guess what, that refinance goes up again another 20%. It's all a win win game when you fix up a home. It's up to you if you want to spend the time to do the work and be amazed at how will it will look after it's done
A lift and escalation should NEVER take over a week. the foundation itself, should never take more than 2 weeks. Setting flooring, tiles, block wall, new wood (if needed), inspection and set the house back down on it.
Good Luck. Hope that my response helped, since the idiots in here didn't really have anything knowledgeable to say.
