So I have learned this lesson the hard way. The answer to your question is YES, there is a difference between what the city (Sioux Falls) will allow you to do yourself depending on whether you buy with an entity or your personal name. My partners and I bought a property with the intent to do a lot of the work ourselves, but we bought with an LLC.
Sioux Falls does issue permits to non-licensed homeowners who are residents. But, if they suspect you are buying it just to fix and sell they will require licensed contractors. Turned out for us, holding the property in our LLC was enough to make it so the city would not issue us homeowners permits and we had to hire licensed contractors for all the work that required permits. So if you want to do the work yourself you may be better off holding the property in your personal name.
Btw, it's not entirely accurate that just because you own something with an LLC that protects everything else you own. It does add a safety barrier, and it is generally worth doing, but if someone sues you they're going to come after whatever you own, they don't care how you own it. If you do the work yourself, make sure to pull permits and have everything inspected. If you hire contractors, make sure they're licensed and insured. If you do that you're relatively protected.
