@Chris Lopez has an outstanding podcast called the Denver Real Estate Investing Podcast, which has loads of excellent  information to supplement all of the great content on BiggerPockets!

not all lenders are nation wide or lend in rural communities are restricted to certain states.

I mastered every aspect of this game until I eventually found out I could showcase my skills at nationwide tournaments and play for very large cash prizes.

Current building owners do not have an outstanding mortgage. 

(Of course, I'm assuming all the tenants are month-to-month - if they're on leases you'll need to wait until the leases are going to expire.)I also find that tenants are a lot more accepting of rent increases when they see that you improve their units and address any deferred maintenance or outstanding maintenance requests that the previous owner may have neglected.

The market out here is strong with a lot of tech companies (including Google and Facebook) and Fortune 500 companies (Nationwide, Big Lots, L Brands, Cardinal Health, etc.) laying down roots here.

Some examples include Nationwide, CoverMyMeds, Mount Camel, Facebook, etc. 

This is a standard thing that they do nationwide, and I prefer this method quite a bit as I know how much my contractors are spending in real time.
