@Derek Wheeler I'm a CPA full time and also invest in real estate so I might be able to provide some clarity here. What I would recommend is starting an LLC (for asset protection purposes and ease & flexibility in business operations) then elect to be taxed as an S-corp.
If you started a corporation or "C-Corp" then elected to be taxed as an s-corp you would get the tax benefits of an s corp but then you'd have to deal with ongoing filing and record keeping requirements. As an LLC, the rules for maintaining the LLC are much less rigorous. It is also usually less costly to set up an LLC
It's pretty common for real estate investors to start an LLC then elect s corp status. Unless your planning to take your real estate company public with an IPO someday, I would recommend starting LLC then electing s corp. This is just a quick summary but, hope this helps.
I also have a bookkeeping business where we handle the books using quick books or xero. We'll be taking on new clients in the near future if that's something your interested in. Always nice to have your books in order come tax time ;) It's also much nicer to run your business with an accounting software rather than excel spreadsheets. The software goes a long way in saving you time and energy and making everything nice & clean.
