Also I should make it clear, I am really not all that successful of an agent, I'm not pulling down huge production numbers, but I'm also not really interested in sacrificing quality of service for volume and Ive not yet figured out how to scale in my way yet...but I've been at it about 3 years full time, so I'm still working it out I feel.  

It helps me to feel more confident in allowing the termination and waiving the fee.

Does this affect a cash-out refinance or pulling out equity in the form of a HELOC/equity loan?

Its like 100 bux a month, meaningless fee for them to handle it all Good luck  That was a momentary lapse in judgement lol.

Because you have to keep the same taxpayer as owner from the relinquished property to the replacement property I'd worry that the legal protection you'd want for a development TIC won't be there.DSTs have high fee but probably are the best path forward for someone who wants to be fully passive and avoid legal risk.

Paid cash for the purchase, and then financed into a HELOC to pull most of my funds back out and have access to the remainder if needed.

I would keep in mind HOA Fees and Assessments.

Real estate is not my primary job, and I travel quite a bit, so having the piece of mind that I don't have to worry about the 2am call is absolutely worth the fee. 

But, if you want to be nice, give them a warning after the first one then start the process the next time it occurs.  6 times in a row means it's probably time.However, if they pay every month and you are collecting your late fee as well... 

Provides “proof” of funds but the account is a corporate retirement plan that the buyer can not access without quitting his job or paying huge taxes, penalties and fees 6.
