. #2 reason is that rentals already bypass self-employment taxes (usually) which is the primary benefit of an S Corp (reduce SE tax plus PTET possibility).There is zero harm leaving it in the S Corp just don't revoke your election.

My fee is usually in the $800-1000 range.

So I guess adding 2 new properties was an extra $250.

I have a rental property so extra documents included things like leases, proof of no HOA on the rental property, etc.

$25 extra per cleaning shouldn't move the needle much.

Usually investment properties will want a 20-30% down payment in addition to closing costs, so it's not going to be a good idea in your current state.

You are required to have landlord seasoning usually at least 12 month some lenders require 2-3 years.

Your 4 financed properties net $250/door - equaling $1,000/month.You might say... geez... for $83/month, why would I want all the extra headache?

That usually doesn't work well... 

In short, in the context of real estate, the majority of your time has to be spent in real estate activities (usually full-time workers in other professions fail at this level of the test because convincing the IRS that you work two full-time jobs presents a problem) and the time spent must exceed 750 hours.
