How much money an addition costs depends on the variables of your home and what you want.

The bigger the project, the more money it will cost. If you're hiring a contractor, you may see a wide range among different contractor estimates.

You may be able to DIY the project, but you must be confident in your skill and willing to sacrifice your time. If you end up needing some financial help, there are some strategies you can use, including a cash-out refinance, construction loans, home improvement loans and more.
