What is the best way to navigate this situation when there is a "buyer's" agent actively involved?

It's best to find a mentor/agent that really knows how to navigate this rental market to minimize risks to your real estate portfolio.    

Hi @Moonhee Kim,By chance, is your husband Korean?

Appreciate the heads up, new to the website and still learning how to navigate communication flow on this site.  

The problem is, with all this noise (literally thousands of aggregation and syndication sites), they are quickly becoming overwhelmed and subsequently hiring an agent to help them navigate the options.  

My perspective from someone that tried to navigate and profit from the 07-08 crash:- Hold lots of liquid assets (i.e. cash) to be in a position to purchase discounted assets.

If you never heard of that before, private lenders are folks - mostly older, well established in the work place or their professions - who have funds such as retirement accounts for which they are seeking safer haven than Wall Street can offer as well as better returns.I personally know of two South Korean brothers in their 20s - immigrants, along with their parents who couldn't even speak English upon arriving - who, in the past three to four years, have developed a "stable" of private funding sources with $5+ Million available to them for their deals.

Rather than having to hunt people down, navigate the city and hope to match up schedules, they got a group of us together at a pub, shared some food and a drink and got to meet with us.

No idea if you are what @Jay Hinrichs would term a professional landlord but from your comments you have the temperament to navigate a lot of the pitfalls encountered in the biz.
