Individually, they are small low yielding accounts but liquidated and reinvested they could, potentially provide a higher return.

I see it and have to deal with the extra time and effort needed to work badly structured and submitted offer after offer, house after house.   

MF little trickier to do as they dont have individual water meters.  

And LLC is one of the options. https://sa.www4.irs.gov/modiein/individual/legal-structure.jsp

Not quite worth the median $175k that these buyers paid for the properties from an individual investor perspective.Let’s dive deeper and imagine you bought these 11 homes as an individual investor.

As to tenants taking care of you, that really changes from tenant to tenant and if someone is asking for extras now then they're likely going to start asking for more and more in the future. 

Remember, prices have to drop by more than your ROE per year just to make your extra work worth nothing.  

It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

I love the idea of real-estate and need some extra money so I might try flipping or wholesaling while building money to find a house to make into a rental.

I’d probably create an operating “shell” entity that did all my business (just you) and then create individual property entities with investors that are used to own each property.
