As @John Thedford would say, and I 100% back this up, If you don’t have the capital or the financial disciplines, get your finances right, get your license, work for a property manager or a broker, get out there and earn some income while you learn the realestate industry and meet people like, investors, experienced agents, property managers, and landlords.

I realize that you are emotionally invested, but don't be afraid to walk away.

Don't get emotional about getting the property.

But they don't ask about learning financial responsibility and discipline. 

Its a rental, a rental is a tool, to make money, end of story, so many get to emotional.

@Eric SamuelsControlling your emotions.

So, basically negotiating price and terms without getting emotional is the key element.

First, try not to get emotional.

I also include a binding arbitration in my contracts because litigation is hugely expensive and emotionally draining so I want to stay out of court, period. 

They can negotiate on your behalf while remaining emotionally uninvolved.
