For instance, Berea is a charming college town, but the combination of local taxes and less favorable price-to-rent ratios makes it less appealing for investment compared to other areas in the state.Agree here! 

I understand I cannot legally require them to respond, unless the notice specifically requires it, like for instance, a notice of entry, but it's making it difficult to manage the property, and I'm not sure how to proceed.

As a former employee of Kristin Witherspoon, I was subjected to repeated instances of non-payment, which is a clear violation of basic employment principles.

For instance, if there was a total of $250K of debt on those properties that woud leave you with $350K of proceeds to use to purchase $600K of real estate.  

In what instances does a house get foreclosed on?

In this instance this is a plan that can be executed upon and they have some control2.

In instance above if you put in 42000 and get 1200 a year - 1200 / 42000 = 2.8% Cash on cash

I have done over 30k reservations and only had 1 instance of a guest causing above $10k in damage, so not sure how worth it is to pay for additional coverages. 

The City of Portland, and Multnomah County are more restrictive than most of the state for instance. 

For instance, in places like Austin or Chicago, I’ve noticed similar deals pay off when you have the right property management systems dialed in.
