It seems that you prepared a lease, the tenant reviewed and accepted (signed?)

I recommend you start with the Real Estate Guides here: http://www.biggerpockets.com/rei/ Also, I would recommend (not just to you, but anyone new to REI) reading the text that brokers use in your state when preparing for real estate exams, so you can understand "quite [SIC] claim deeds" and other real estate fundamentals.

Perhaps that will change in the future.Mini-storage is a business and you have to be prepared to run the business.

Now every time I see wells Fargo involved, I prepare myself for all wrongs and delays that could only happen with them.   

Looking for tips on options, things to look for, potential problems, how to prepare for appraisal to get best valuation...

I'm a tax preparer, specializing in personal income taxes, with prior experience in the workers' comp industry.I'm also an accidental landlord.

Be prepared that it is a commitment, and you will need to study pretty diligently to finish before the course expires.

@Joshua Berube When you say rent to own are you implying:1) a lease (rent) with a separate option to purchase at a preset price; or2) an instalment where you set the price now and begin purchasing the property.The CRA has a different outlook on each and the tax implications will be different for both you and the vendor.With scenario 1) you really do not have any equity in the property, so you will likely encounter difficulty pulling permits, etc in preparation to demolish and rebuild.  

Always be prepared for the unexpected!

What else should I be prepared for?
