With 65 units, I have a revenue manager who is checking it daily. 

This is virtually non-existent with SFH's but is commonplace with 2+ units.

Two repairs can often cost as much as a new unit, and manufacturer warranties can be a headache to use.

I’ve had more success filling vacant units by word of mouth/ networking with other agents in my market recently than I have through the typical advertising methods.

I had listed a 10-unit property in Cincinnati, OH, and found a buyer through an agent from a different office.

I'd estimate that there are less than 1,000 legitimate, or "professional" wholesalers, in the United States of America, as defined by individuals who make $100K flipping contracts, and collecting assignment fees, in any form, and who have made that amount of income more than 3 years in a row.

Today, I used those proceeds to purchase a 5-unit commercial retail building without coming out of pocket at all.

Consider using an FHA loan to secure a 1–4 unit property with just 3.5% down and take advantage of tax benefits by living there for at least two years.

I have them on several units and no issues.

Many of these are low income, government subsidized housing units.
