I generally incorporate a small increase in rent into all renewals, just to keep up with rising expenses (e.g., taxes, HOA fees), inflation, and fair market value.

The seller owns it in an LLC, not an incorporated entity. 

Almost half of the publicly traded companies in the US are incorporated in Delaware, as are many major banks.Delaware’s tax laws allow corporations to be taxed at a low rate in Delaware and avoid higher taxes in their home states.

If you incorporate, you will need to check with the Secretary of State and make sure that there's nobody else using that name.

If you are in a city that has been incorporated multiple times, was part of unincorporated in 1969, then incorporated into this city in 1975, then was unincorporated again in 1983, then finally incorporated into another city in 1990...you might have to visit various jurisdictions and look up their archives.(2) After you have determined when the zoning of SFH was put in place, you then need to determine what year your house was built, and whether it was originally SFH or converted later. 

My mom said that there are many benefits, but it's so downright different in terms of loopholes and benefits on complicated tax returns that she's glad to be retired and not elbow deep in corporate tax returns.

Second, when doing the math (the BP rental calculator is excellent), incorporate the HOA dues.

I think it Costs around $50 to incorporate there and maybe $100 tops for annual fees.

@Pepper Bradford Perhaps you are missing the primary purpose of incorporating, which is asset protection, not tax treatment on a few grand a year. 

However, they do have an app for cleaning and maintenance which integrates reservations and can incorporate checklists and work orders etc.
