You want this to be your backup plan if things take longer than anticipated, you do not want to dip into personal credit cards so i would use a heloc to help with down payment but try to keep a nice available balance on a heloc as your insurance policy. 

I don't charge for anything under though especially if the guest was easy overall.

because I was paying my bird-dogs vs having them pay me and just promise how someday, maybe just maybe they will bring the grand-slam of a deal and then I will be paying them oh-so much $$$$$ Seriously, from those buying into this I gotta understand how your mind works, no insult meant, I am genuinely intrigued and baffled because if it's a good deal you can go to any number of investors and get $, not a one will charge you for the opportunity to present them deal. 

I rented out the additional bedrooms to friends and family, charging them well below market, and sold when it was time for my wife and I to start our own adventures.

The tenant pays a monthly premium and keeps an active bank account and credit card on file.

Typically people charging for that service are doing it because they need the money...if you catch my drift.

The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

For all you know it a violent situation and she could get a judge’s order and you pry couldn’t/shouldn’t charge then. 

I already run up expenses for my trading income on a credit card because Im responsible and its helpful when building credit, Im also on my families card or something of that nature, but at my age I am not entirely sure what the best course of action for credit building is any tips would be very helpful!
