The lower rate and fixed terms are more attractive.  

Course there are other really scary signs such as the return of No Doc loans, very attractive credit options, easy access to other funding, TV shows creating a large class of buyers that think they can get rich quick by flipping houses and the huge surge in interest for "passive investments" by people who may not be prepared to properly vet the provider or to live with the problems when they come up. 

I try to avoid a lot of 1/1s because they don't attract stable tenants. 

Quality units attract quality tenants.

Are the suburbs in better condition and attracting better tenants?  

A 10% return in today's market will be very attractive to a lot of people, and you could offer that and still save a bundle vs. a hard money loan.  

Twitter, like all social media is about mass,  The more mass someone has the more followers they attract.

Would the price ever be attractive enough to give it a go?  

Get to the point where you have an intuitive idea for what deals look good, so that you can pass on the 99% of mediocre/crappy ones, and only investigate the attractive few.You need to learn to value deals better than the realtors, because their incentive is to complete a transaction and move on, unless you have a demonstrated capacity to do several deals in the near future.

Although SFH doe attract better tenants you just have to be specific in filtering your tenants.
