I don't know what it's like to be a billionaire, but I'm guessing they didn't get there by listening to pitches from amateurs.

It's important to know your law, one of the biggest failings of amateur investors.Do yourself a favor: buy "Every Landlord's Legal Guide" by NOLO.

You will better understand the law, and you will develop policies and procedures that enable you to manage more effectively than an amateur landlord. 

Quote from @Matthew Bowling: I suspect the Landlord is a typical amateur that failed to increase rent over the years.

Worked on photoshop and made a nice logo (I'm a hobbyist photographer and very amateur graphic designer), and am working on a website, company email address and business bank account right now.

Investors must do their research and find a REALTOR that understands investments, landlording, Property Management, etc.Unfortunately, the qualified agents don't want to waste their time on amateur investors.

It sets apart as a professional among amateurs. 

I can't be successful if I'm involving amateurs in my decision-making process.

I am a amateur landlord who is looking for opinions on what others would do and have done in this situation.

Any amateur can make a roof look good, but you may not find the problems until five years down the road.
