The master bath in the house my brother chose is larger than my bedroom and his closet is the size of my kitchen.

Take your $100k and put it in your back pocket and go find 10 other people from your RE meetup with 100K and put together a larger deal in the Indiana market.

And if it is, can my personal LLC withdraw 50% of the profits (rent, gains at sale) legally? 

If you have a RE license/real estate is your full time profession, you pay reg taxes on profits from selling real estate- I buy and hold for at least a year and sell some flips periodically so that is not my main business and I pay a much lower tax rate as mine are capital gains

Are properties that are profitable grouped together forming the micro-markets you are looking for?

Also, I am considering building a storage building larger than 120 sqft.

It appears to be a larger issue than a bug in the app.https://play.google.com/music/listen?

I was told not to be greedy, which is fine, so the overall profit on my end I went down on.

Can i charge 150$ as an application fee but set rents at 10% lower than market to get the best possible tenant and profit off the rest?

Also, make sure you hold on to a property as a rental so you don't end up being designated as an IRS "dealer" (a tax term) that takes about 1/2 of your profits.
