Its hard to reach the 1% rule here now. 

The FCC rules are here: https://www.fcc.gov/sites/defa... 

There are rules to follow!

Consulting a tax professional or financial advisor familiar with these rules would be a wise step before making any decisions.

Looking for something with low acquisition cost, and meets or exceeds the 1% rule.  

When you have studied your market properly you should be able to provide the answer of if single family or residential multifamily is better for cash flow. 1% rule was for a time when almost all deals were decent as a way to rule out the lessor deals and concentrate on the best deals.

Even in philly in D class area it is tough to hit the 1% rule.

In Columbus, you can still find the 1% rule and there's amazing appreciation potential due to how much population growth, job growth, and companies moving/developing there (recently Anduril just announced another 4,000 jobs coming to Columbus Ohio on top of Intel, Google, Amazon, FB, Nationwide, Ohio State University, etc.).

Depending on where exactly the property is located they may have some different rules/laws in place.
