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?  

You'll need to find someone in your desired market who eats, sleeps and breathes valuations to get a full idea of your cost in and your expected cash out.A buy and hold strategy is good if you don't need large cash flow and don't mind looking at residual income.

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.

I obviously would rather have the tenants pay but, would that make my rental less attractive?

That is unless you have a management company that eats, sleeps and breaths property management and lives on site. or the property is in a transitioning area that is moving from c to b, or b to a and better paying residents are moving in. 

The only thing really attractive about it is the owner financing..

This will extend the life of the floor and will give an apartment a fresh look that will attract tenants.
