Pros, pros, pros. Bullshiet.
Obviously, none of you giving this advice have ever even sniffed owning a portfolio of rentals. You'd go broke if you hired a "pro" every time you had a problem.
And, that's assuming the pro did a good job. My experience? A LOT of "pros" don't. They shortcut or don't give you what you paid for. For instance, they'll water down the chemicals needed. You usually don't find that out until after the fact.
To each their own.
