And now you have access to me and my people (and of course you can meet your own people)! 

I don't have access to the MLS to run comps.

Remember, no system is perfect, so avoid the temptation of constantly chasing after the next shiny object.

For us, we do batch showings instead of individualized showings; it cuts down on labor cost of having constant showings and it actually incentivizes competitions among the "applicants". 

If you need access to the $200,000, you could use a HELOC to temporarily pull equity from the property when good opportunities arise. 

We have lived in our apartment for nearly three years without any issues, but since April, new neighbors moved in upstairs, and the noise has become unbearable.At all hours of the day and night, it sounds like constant walking, furniture screeching, and items being dropped—even until 4 a.m.

You even graduated from IU so you have access to some awesome loan programs from IUCreditUnion.Keep your job and connections to buy a house, then rent out rooms to traveling nurses. 

I have only done a few deals but the thing I constantly having to remind myself is R/E is a long game. 

Unfortunately, Texas has a law prohibiting HELOCs on rental properties and I believe they also have a 70-75% max total loans allowed on the property which cuts into the equity I've built and would only allow for me to access 30K which would make it less appealing to go through the process for only 30K.

A licensed property manager should have access to the MLS which would put you on realtor.com, Zillow, and probably a dozen or more other websites.You don't need professional photographs, but they should be improved.
