We sit around a fire with friends , drink a bit too much and sleep in the camper . 

The way you opened the topic left me thinking that you're asking a moral/ethical question, like "how do investors sleep at night?".

It will make you sleep better at night. 

This isn’t typical living noise; it’s loud enough to disrupt our sleep and daily lives.

I sleep a lot better at night.Good Investing.

Yah I vote we just sleep in the bed we have created a stagnate economy could be worse peoples!

I feel like I am sleeping with the enemy..Yes, you can escrow the rent until it is fixxed.

Additionally-Sleep a few nights in it.

They're good to have open access to capital/cash/equity to a property ahead of time so you can execute a deal or purchase when the time comes on a split second decision (versus having to apply to a loan at that time which might take 20-45 days to get approved/closed/etc plus by that time you dont know what your future income/credit/assets will be like in order to qualify anyway).The second use is sleep at night factor and having a reserve of capital in the event an emergency event occurs in life.For these two reasons is why I use lines of credit.

Plus, a PM needs to be managed, if the house is across the street you'll probably sleep better at night if you're in control, the extra cashflow will be nice as well!
