But sometimes life does happen, and if my communication with the tenant is good, usually we can come to a reasonable compromise. 

I thought it would be a nice compromise between fully handwritten and printed.

Where the ethics become compromised is when a tenant is put into the unit purchased in this manner without first informing that tenant of the facts of the situation.I can say that some of the entities purchasing second position NPN are also using this same practice, as I know somebody involved with that and I was so informed.

We tried to find a compromise with them multiple times, but they essentially moved out in 3 days and stopped responding to us.

We're going to post the 3 Day Notice to Quit, as well as a letter explaining that if they want to avoid a legal filing for rent and fees due, we need a signed agreement stating their intent to vacate and hopefully a compromise amount. 

Or I can walk away if we can't come to a compromise.

With house hacking a SFR, you usually have to compromise on things like privacy, especially if you go the rent by room method and share common spaces like living/dining and kitchen areas.

There are several factors I am now considering when looking at a property in Rhode Island and a compromise will have to be made somewhere in order for this plan to work.

@Michael Moreno I might go against the grain here but consider compromising paying your mortgage off in 15 years.

What responsibility do you have if tenants, say, shop online and somehow your network is compromised?
