(They have other properties throughout the area listed as "approximate location" and not just this one, but most are listed as "location" with development name, street name or near an attraction.) 

Seller financing is also quite attractive, though I guess there are few of these kinds of deals available. 

Here’s a comparison:Income reliability and net cash flow: In Las Vegas, a fourplex in reasonable condition costs about the same as two single-family homes, but they attract very different tenants.

I’ve included a photo for reference of the kitchen which is the main attraction of the Mass home.Now I am looking to pursue REI long-term and am looking for tips on how those more experienced in the field have operationalized and scaled the property selection process.Our thinking for this first official investment is to either acquire a duplex/triplex and add our touch or acquire a single family where an ADU can be added.

@Kyle Carter just because a building has all section 8 tenants doesn’t necessarily mean that the cap rate will be higher on exit but it might attract a buyer(s) that are focused cashflow and not appreciation; therefore a lower price to juice the yield.One of my non negotiables if I were you would be to only buy in an area that is desirable.

I'd try to get a 6-month lease at a below-market rate to attract a tenant.

Well, those properties will statistically attract corresponding Class B & C tenants.So, how should an investor account for Tenant Payment Performance/ DEFAULT in their analysis? 

This often attracts broke tenants you will have to soon evict.

 @Jake Baker Love that strategy by being to attract tenants with affordability and getting the stable monthly cash flow compared to weekly rentals which may have a higher profit but a much higher risk making them not really viable in today's market.
