I am an experienced investor and unexpectely find myself managing a duplex myself and wondering if there is a small landlord (aka inexpensive) simple solution for marketing, background checks and lease creation that markets on zillow? 

The key for me wasn't to invest in the 'best place' but to know a market so well that a deal jumps off the page when it appears.

Logan county has the highest price per square foot new build in our market right now almost $400 per square foot.

From there we identify properties that could have some potential and if you are interesting in diving deeper, 1) we do a thorough video walkthrough to give you a realistic look of the property, 2) we give a ballpark estimate of rehab costs (we do 40 a year with our GCs o we will get pretty close), 3) we talk through market rent with our property management team, ARV, and potential highest and best use.Ideally you find great investor agents who know their market really well and have a network of resources to provide you with enough confidence to take reasonable action. 

On my new builds we hit the double cash on cash in certain markets sometimes its only 50%.

I'm not super familiar with the real estate market in Couer d'alene like I am with East Idaho or even southern Idaho or the Treasure valley.

Then they will start the process over.As for finding a market. 

Quote from @Shayan Sameer: Quote from @Samuel Diouf: Columbus, Ohio is a great market to consider if you're looking for appreciation markets that still have cashflowing deals under $200k.

Thus, the realistic options are 1031 to DSTs or sell, pay tax, and invest in marketable securities!?  

In many ways, this is the best market for buyers in Austin in years.
