There is so much more to that relationship than just the financials so make sure you actually like the person and that they are honest and ethical like yourself!

I would recommend finding a good, quality, honest and ethical lender and sticking with them.

From my perspective, you should have no reason to question the ethical, moral, or legal act of your decision to receive prepayment of rent. 

These are professionals with additional training and a stricter code of ethics.

I've got my mother's work ethic and the carpenter logical mindset of my father.

A good friend waited two years to get their deposit back due to strategic moves by a military landlord to avoid/delay repayment of deposit on a poorly cash flowing rental they owned (I believe they wanted the deposit to handle repairs they couldn't afford or want to pay for that were not the tenants responsibility).BP Service members, is it ethical to delay handling tenant disputes due to a deployment?

These are professionals with additional training and a stricter code of ethics.

Just from an ethical standpoint, I'm sure you contract has outs for you, you should let the seller out if they really want to. 

It’s reasonable if the tenants saw them they assumed they worked or even if you said they were broken that they would be fixed.With having nothing in the lease and hopefully having the desire to be an ethical person In my opinion you should fix them or replace them.

With my work ethic and personal wit, after all said and done, without to much explanation here, I think I could do amazing in this field and I love the grand picture of the profession.
