Seems like a good deal...

Found on MLS, 4 unit in desirable location in CO. Expensive at $880,000, after rents calculated on the low end of possible and expenses factored in it would cash flow $800-$900 per month, CoCROI is at 6%.

I have listened to many people smarter then me say if it cash flows its great, if the CoCROI is below 12% skip it, 1% rule, 2% rule 50% rule etc. 

What advice would you have for someone new to multifamily investing, currently own just a SF

This is with asking price

Stop trying to use percentages to make your decision.  The day you start spending percentages, you can start using them again.  Use dollars, and ONLY dollars to make your decisions.
