This is going to sound harsh but if tenants lock themselves out, they're on their own. 

Yes, you will have drama and issues but I can tell you that my returns are through the roof.

SFH might be less tenant drama and easier management.  

I hate to be harsh but ....Leasing a car is foolish and costly  .

Not to be harsh, but if you don't know what RUBS is, you're under-educated for multifamily investing.

Ditto on online applications, makes it so much easier, no drama trying to meet to collect app fees.

Came for the multi-family info, stayed for the drama.

If the home is newer and in a more upscale community, the likelihood of drama is lower, (though never eliminated), simply because common life events, (car issues for instance), are less likely to financially derail a tenant with a higher income; they are simply more, (financially), resilient.An alternative, if you don't want to engage ongoing management services, is to  simply hire a PM to get it leased.  

It must be decided by a "trier of fact" (a judge or jury)If you like drama, want to learn all kinds of things about law you had no idea existed, have a bunch of money to throw around and frankly are currently bored, by all means, Use A Quit Claim Deed.Or, take some kind advice - don't do it.

Gave me a laundry list of things I need to fix and drama the second I entered.
