Tips for converting attics and garages

[Jonah Kolsrud]

I am currently in the market to buy my first house hack in Charleston, SC. I am looking for creative ways to add value to a property and have seen a number of posts on converting garages/attics into bedrooms. I am wondering if anyone has had experience with this and could throw some tips/tricks in what I should be looking for in a house to see if this is possible and also what major pitfalls should I avoid.
