20% gross rental return in Orlando? Elsewhere?

[Brian M]

I am recently back from a family trip to Orlando. On this trip I noticed what appeared to be numerous single family home listings in the $50K range with market rents that appear in the $800/mo range... for about 20% gross rental yield. These were properties in what appeared to be stable middle class and lower middle class areas.

I am not currently a property investor (other than my primary residence), but this type of rental yield, even after expenses, appears quite attractive.

For those that are in tune with the market in Orlando, do my numbers seem correct?

Also, I have no allegiance to Orlando. Where else across the country might this 20% gross rental yield exist (AZ, Las Vegas, TX, Atlanta)?

Thanks!
