I’ve got a good handle, even if just basic knowledge, on repairs, repair process, and costs. 

Not as much for basic education, the topics last year were for more intermediate/advanced note investors.

It basically means that if you think "I'm an attractive and lucky person.

I am a licensed master electrician, I work for a contractor (great pay, benefits, work truck, etc..) but also own a fully licensed and insured electrical contracting company I basically have just set up (been open 3 years) but no time to do anything with because I am constantly working on both houses.  

My dad basically required each of my sibilings to own at least one income property.

As long as you now have interest in the principle of the property.  

The principles remain the same: you still need a LOCAL team that you trust: Realtor, Contractor/s for starters, and a great Internationally experienced Tax Accountant back home...

However, it is good to get the basic knowledge to avoid the most common mistakes.

The lender will want to know that you are clearing enough in NOI to more than cover the principle and interest of the loan payment.

If the buyer doesn't have an agent, I would guess that you'd probably at least be able to at least come to an arrangement with your agent to take a reduced commission, since otherwise they would be basically getting a double commission for very little work.Also, just bear in mind that if they do make any of these adjustments for you, they are doing you a favor.
