I personally have success in doing flips with my partner here in Ohio.Lakewood and Edgewater are gentrifying neighborhoods in Cleveland.

I have considered it but I keep things at a flat rate for the exact reasons you stated.I want people to get the exact price when they stay at our lake house.

I am the only person that will be able to update you in this matter.

A new person moves in and she says the upstairs neighbors are creating a ton of noise.

Is your goal to use being an agent for your own personal investments or actively try and grow your agent business to eventually leave your W2?

Remember that for most owners, their business is very personal to them.

If the management fees stay in Sch-E, it is exposed to ordinary income both at Federal and state level, which is way higher than SE taxes of 9.55% (15.75-6.2 (personal social tax already maxed out)).2.

I have no personal experience with them but they are the only company I know of that are built more for self managers and small portfolios. 

You could sell one house and buy two with that money. 

It will still be reported on your personal tax return.
