I collect apps and fees, then grade them based on a number of factors- rental history, income, credit score, reason for leaving their last place, reason they want this apartment/area (close to school, work etc), whether or not they smoke, if they have a helicopter parent (I rent to a lot of students), how long them plan to stay in the area/apartment, when they need to move in. 

They are hands-off, institutional grade real estate investments, and they allow you the option to diversify.

More than likely you will get non-investment grade tenants depending on the market you are investing.  

Let's say you have no 4-plexes comps in the area but there are duplex comps:1) 2000SF duplex #1 sold for $200,000 -> unit size: $1000SF2) 4000SF duplex #2 sold for $300,000-> unit size: $2000SF3) 1200SF duplex #3 sold for $150,000-> unit size: $600SFlet's assume to make things easier they are all the same grade of quality and they are all leased to tenants at market values.Duplex #1 sold for $100 per SF and $100K per unitDuplex #2 sold for $75 per SF and $150K per unitDuplex #3 sold for $125 per SF and $75K per unitNow you have numbers you can compare to your 4plex.

Don't forget the basement bedroom must have a egress window (2 exits required) and if its below grade it has other requirements.

As for other online resources, www.neighborhoodscout.com offers "Investor-grade insights for every location" (i.e. market data, price appreciation, rental rates, vacancy rates, etc).  

As for condition of the property from what I've been able to tell on the listing the building is your basic investment grade from about 10-15 years ago.

Congratulations on finishing school for Pharmacy!

We really like that area.Gentrification potential: Grade B+Jefferson-Chalmers/CreeksideJefferson Chalmers has been called “a diamond in the rough,” with more than 160 acres of riverfront parks, boat launches, fishing and outdoor recreation opportunities.

I'm still working on if that is an assessed value last sold price recorded or a mixture of the two to arrive at a valuation.Zillow estimates the value of the home at 123,119 it is in a solid C neighborhood (possibly low B not 100% sure of the neighborhood grading scale still learning) It is in a neighborhood of other home that has a weber county parcel search value of 100k+ and Zillow value of 125k+It looks like a good candidate for a flip or the brrrr strategy.
