@Matt Motil - You hit the nail on the head.

Matter of fact when he had me come to his Christmas party at his home ( 2 million ocean front digs) I asked him you know your much more polished than most brokers who work for r me and he then explained his past job.Even today most agents did something else in their career's  rare is the person like me who started at 18 and never have done anything else.I work with no less than 20 brokers in 12 states..

And having helped hundreds of other investors do the same, I believe I've nailed down a successful system.  

A friend of mine once said "When you are an Energy Analyst / Building Automation Programmer, all of your problems look like a nail." 

He of course came back to sabotage my roof my driving long nails into it creating a leak that damage drywall.

Stop speculating, nail down your criteria, stick to your criteria, and only buy at DEEP discounts from MOTIVATED sellers.Good luck.

There are some 4 unit buildings in older parts of Westminster 72nd and Lowell-ish as well.You hit the nail on the head about inventory - there is nothing available in the Denver Metro - I just saw today that year Feb 14 vs Feb 15 there were 25% less listings.

The only problem with that is like it is a nail polish, when it starts to peel off, it will start to look ugly, just a thought.

I think @Steve Vaughan hit the nail on the head in terms of your drywall issue.  

Kevin F.has hit the nail on the head.
