How much income is the property currently producing? 

Lot rents at $250 and running at a 40% expense ratio produces only $16k/year net  Is it worth it for the massive amount of work this place will require?

I can see a ton on the web, but don't know if there is something that generally stands out in the real estate community as a cut above. 

I own 30 properties in western PA that produce cash flow, but no appreciation. 

Working with web and app developers to create best-in-class management tools that drive down costs, streamline processes, and attract and engage millenial customers.

They are all in c class areas and produce very well.If you plan to enter the C class investment world, I would suggest that you have a plan to scale up.

Just ball parking on the numbers you gave, in which it appears that 11 units are producing the current income.

Long-term I'm hoping to build a portfolio of cash-flowing properties that produce enough income to live off of! 

I don't have any experience with them.however since they are CA based and did not post a CA BRE license number or CFL or NMLS I suspect they do not lend on 1 to 4 units as those require those above licenses if your in CA.Also I am always a little curious about those that say they lend from 20k to 20 million LOL.. no one can make a dime on a 20k loan... so thats curious.Lastly and this is just a personal pet peeve I just don't care for companies that don't list their principals and a small bio on their web page so you can look into the owners on google and make sure they are upstanding citizens.. again maybe its a marketing thing and maybe I am all wet but thats my preference I want to see who the principals are... they should be proud to put themselves up there ( again my pet peeve LOL)Just don't sent any up front money..

My recommendation would be to get into the local REIA AZREIA.org they are one of the best in the country and you can learn tons and meet seem great contacts.I have looked at some of the 'flips' in scottsdale and in my opinion many of them are Subpar so if you produce a superior product than I would imagine that as long as you can find the right deal you will not have any problems.
