@George Zev I have both an S-corp and a Partnership in Colorado. The only cost is $10 each per year to stay registered with the Colorado Secretary of State. Until you have established track record you probably won't find a lender willing to help you acquire (mortgage) a property in the name of an LLC. However, once you have the proper paperwork in place you can open bank accounts, get credit cards, have utilities, etc. For flipping my accountant recommended an S-Corp (flipping income is handled differently and so is insurance). For holding, a Partnership or LLC is fine. The paperwork you need should be available online and cost to set up is minimal or free. Articles of Organization (depending on the entity you choose), Statement of Authority, Operating Agreement (can be optional), Employer Identification Number (EIN). Your entity will need a name and you can check the SOS database to make sure there isn't someone out there already using the name you choose. Other than lending limitations, I can't think of any cons - always better to have clean, segregated bookkeeping and general separation between what is "business" vs. what is personal. Tax implications? Check with your accountant; but all profit/income should be pass through and show up on your personal return. However, you will have to file a return for your entity and if you don't do that yourself then you could end up paying a tax preparer.
