So I'm in a unique situation where I own a property worth around $213,000 that is paid off.

@Ross Flaharty doing a true calculation will be challenging. 

My challenge is limited time with the demands of medical school and family.

@Frank Crianza The BEST advice/tips/tricks I can give - I have already given ... research is one thing, but obtaining the financing is another - I have a boatload of assets and a ton of net worth but obtaining "good" financing is a challenge without a paycheck from an employer ... you can find short term financing with higher rates and costs based on the value of the property you are buying, but you will find it difficult to obtain good long term financing for long term long term investments while self employed

NZ is one of the least affordable places to buy in the world believe it or not so the barriers for people getting into their first home (20% deposit) are very high and challenging.

It's extremely unique.

It has helped build a great relationship with the sellers we work with.Just thought I share some of our experiences dealing with sellers.You guys run into some challenges?

Unfortunately hindsight is 20/20  however I decided to do something about it  my first step was to create my own business about four years ago on HR outsourcing and consulting  which increase my income pretty well, however scaling it up has been a challenge, Specifically after I got hooked on real estate.

Crime statisticsFind a real estate agent that is investor friendly that will help you understand the market, and even more important, find investors that you want to emulate, and find a way to add value to their operation in return for them teaching you the ropes in your unique market.I will leave tax liens for someone who is in your local area and knows how Georgia handles things. 

Side note: I think it would be cool to have a small meetup for landlords / wannabe landlords to discuss and share tips on all the peculiarities that come with this unique territory.
