Some of those financial assumptions are overly rosy. I did my finance homework and leanred a 5% vacancy rate implies one month every two years--nice if you can get it, but not necessarily realistic. And 10% seems to be the typical management fee, so the management + maintenance figure would need to be higher than that.
Also worth considering: if you can make a sound investment in a house for little money down in a neighborhood with good prospects, why don't your tenants do the same? Perhaps one has overestimated the prospects of the neighborhood or the creditworthiness of one's tenants.
