Will I just have to pay Self-Employment tax and Federal Income tax? 

Go to your county recorder's office and request the lists (they may also have self service computers to look up these files).

If they will, I'd make sure I'd get a policy for the value I believe the property will have after I do the repairs so I'm not self-insured.

note to self: always read @Steve K.s post before responding. what he said, :)

My interests related to real estate investing are househacking, buying rental properties, fix and flips, and the BRRRR method aswell as learning more everydayALL WE NEED IN THIS LIFE IS FAITH, BELIEF, and EACHOTHER“My self”, “I” , “Me”, “Us”, “We”, Use these words when you speak about yourself to yourself.

I am looking for landlords that self-manage their 100 doors or more residential rentals (SFH, duplex, triplex, quad, 10 units or less) to discover better ways to manage, automate, and better systematize the process.

Responsible tenants, with healthy self respect, won't want to become freeloaders.

You would have to self-manage?
