Concentrate on savings, living frugally will be your best approach to increasing savings.

Let’s concentrate on the current one.  

Those requirements are: Reserves savings over 10%, No litigation, no one party owns more than 10% of the total units, low renter and high owner concentration, and sufficient insurance.

First off - I'm total noob so trying to learn a lot.I'm looking to buy a condo or townhouse which I plan on keeping long term as a rental property.From looking at Zillow I noticed that there are some large-ish neighborhoods where there are few to no properties for rent, and others where there are several properties for rent in a condensed area.All things being equal, is it better to avoid areas where there's a high concentration of rental properties?

Skip, I am having the same issue, but with more concentration.

     I'm doing really well in areas around the greater Palm Springs area but am feeling a little concentrated, would like to diversify geographically. 

Concentrate your efforts on finding a job and having 2 years of steady solid income before considering purchasing a property.

Your activity level in Flight School will be intense at times, and I would suggest you don't need other distractions from concentrating on perfecting your aviation skills. 

I would put it on the low end of your priority.I would concentrate on knowing what taxing jurisdiction you truly are in first.In regards to Ohio I would recommend filing the return, however you will most likely not have any tax due. 

I currently work in the human resources department of a petroleum company but would love to leave my 9-5 to concentrate on things I enjoy.
