Tenents, time intensive?

[Chaz Moore]

I'm slowly working my wife into the realm of cashing out refinance to buy an investment property but the big hangup I'm running into is the time it will take to manage tenents.

I understand some can be a pain in the but but moderate to good ones shouldn't take up much time. Am I wrong?

My father in law has two 4plexes and he is on the phone, it seems like all the time when he's home. He's the type that will always answer his phone no matter the time of day. And I believe that opens him up to disgruntled begrudery. From noise complaints to someone breaking the dryer from having nails in his pockets. I believe in hookups not the actual appliance.

TL:DR

How much time does it take to manage tenents once their in place?
