@Kevin Holmes -  mentorship is a romantic Hollywood idea.

A family necessity, a job transfer, a romantic involvement, or just having an enlightenment and wanted to walk the earth?

I think he has a romantic idea about building super efficient units to cut down on utilities.  

They don't want the romantic notion of high returns in quick time with minimal effort to not be true.  

There's no reason this would be any different, marital status or romantic involvement in general is not any sort of requirement in 2016.

Also, let's not be romantic about living in our investments.

I think anything over $100 positive cash flow is a good deal, especially if the property is located in a romantic location with lots of appreciation… You're benefiting from owning and controlling that asset, while your tenant is making the payment!

Those partnerships are sometimes more intense / complex than an actual romantic relationship and you really need to vet your partners prior to going in on a deal. 

However, in this deal, you are akin to the third wheel in a romantic relationship.There is no need to go into panic mode.

Your post sounds like you had a romantic interest in her.
