Ill shoot you a DM I know a great broker there that can help in home selection and contract negotiation, but cannot improve the ROI if it simply isn't there

First, whether you are renting or selling these are two rooms sellers and tenants place greater emphasis on when selecting their housing.

The difficulty was not finding properties that would make money, it was selecting the property that would make the most money.  

To avoid going through the same poor experience, keep reading.Even if someone gives you a referral here, do NOT make the mistake of assuming that the PMC will meet your expectations, just because they met the expectations of the referral source.In our experience, the #1 mistake owners make when selecting a Property Management Company (PMC) is ASSUMING instead of CONFIRMING.It's often a case of not doing enough research, as they don't know what they don't know!

On average, the profits from such a strategy might be higher in Boulder than all but a select few markets in the country (maybe certain parts of SoCal offer slightly better opportunities?). 

You have to be quite selective and in some cases make some changes to the property to make it cashflow (ie add a garage, renovations etc).

Better tenant selection and regular inspections will stop this from happening.

Find the lender, agent, whoever that meets those values, then execute upon selection.

Then open a new Google Sheet file, click Open and then select Upload.

@V Reddy First, setting up an LLC to invest in real estate is generally to limit personal liability and for asset protection (select "magnifying glass icon" in top-right corner and search "LLC", you'll get a lot of feedback).
