It's all about mentality and perspective.

Now, that letter might not have been from Castro (is he even mentally competent to do so?)

Mentally it prepares everyone for the expectations and formalizes things you may have said.

.,  My advice would be to put yourself in the buyer's shoes and mentally walk in the house for the first time so you can visualize their reaction.  

That mindset serves millions of investors on this platform well each and every day, and the positive, selfless willingness to help others get started, succeed, and invest is what makes this platform so great - and incidentally that's the mentality that will help you win far more business from BiggerPockets over the long run.I'd encourage you to start here to review who and what we are at BiggerPockets.

But I'm in a good mental space.

Sounds like you have the right mentality for this business as well!  

A family of six hoping to rent a two bedroom apt, a mentally challenged woman with two small children trying to escape an abusive husband, and a young couple, maybe nineteen or twenty, who were looking for a place they could share with his parents who'd just had their trailer repossessed are some of the people who applied for my most recent vacancy.  

Individuals that purchase to rent are not of the same mentality and not the same quality of owner as the owner occupied units.

I dont just have a "lets-go, NOW" mentality, in fact, I probably am more "let-me-dwell-on-this-a-bit-and-by-bit-I-mean-a-month-or-two" before making decisions.
