Betting on future price appreciation and equity growth is just that "betting". 

I did buy a website which was expensive and produced nothing, still trying to decide what to do with that sunk cost.

@Devin James My bet is on that they close. 

Another way is to check out this website.

Nothing is a sure bet.

First, there are small grammatical issues with their website that could indicate it might have been built by someone whose native language isn't English. 

When you have a duplex and tenants on both sides stay for ten years, it almost guarantees that something isn't right.I would study your market and determine the value of your rental, because I bet you are losing money every month.

Is this just someone betting big on inflation?  

The debt may not report to your personal credit (unless you are late on or miss payments, then all bets are off)2.

They can serve the initial notice to vacate but the actual court filing needs to come from you as the owner or through an attorney.Given you're out of state, working with a local eviction attorney is definitely your best bet here.
