If I had a few (1-3) properties then I'd probably want to make sure I could stomach a short-term scenario where there was zero income from the properties and I still had to pay expenses. 

I think I could stomach ~$30-50k in student debt.

Although this couldn't be further from the truth you still need to deal with that pit in your stomach for months until the evictions are final.

I don't have the stomach for a lot of risk and I only want to deal with A+ tenants so this seems like a safe easy investment with a good return.

Sometimes you will be able to throw in tenants and they won't trash the place too much, but beware about damage to the property.All in all, if you are able to have a good property manager or live near the property yourself and can stomach some damage to the property, the cash flow will be worth it.

I don't have the stomach to buy in those neighborhoods, the return on paper is always better than the return in reality.good luck.

Thanks again @Charlie MacPherson.Looks like if I can stomach the commute there are some nice opportunities in the 5 more south locations.

Don’t go looking for additional stomach acid, because you’ll find it.

Until that changes, you should do lunch or coffee with whomever you deem worthwhile, join a non-competitive networking group, join a community service group (or 5), get involved in local government (if you have the stomach for it), get involved in your alumni association (if you don't have the stomach for local government), and be an extrovert, no matter how uncomfortable it might be at first.That's what I've done, anyway.

For larger houses (which I dont have the stomach for that level of risk yet), I would reduce that %.Also something to consider, around me new houses sell for 10-20% higher $/ft2 than older houses.
