If you are using RE investing to try to avoid going to school, your intentions are not in the correct place.

Unless you negotiate a new contract or addendum with your PMC, they do NOT have to abide by any requests/demands you make that contradict what's written in the management contract.If they have in fact NOT followed the terms of their contract, then you'll want to send them something in writing pointing out the specific language in their contract that they violated and ask what they plan to do about it.If they fail to correct or address the issues, then you'll want to start looking for a new PMC.

You are correct there certainly are ways for things to be done badly or illegally, but these are BAD MESSY situations before a sub-to deal would even be considered.

HI, 
Is opening a LOC on my primary a good option to fund flips or is there a better solution to get the funding? There's no charge to me to get these funds except a yearly fee of 200.00. 

Thank you 

Again, all answers that might be better answered in private.You are correct that a lot of lenders just don't understand how we work as investors but that's why some of us hang out here. 

Are there any tools or strategies you swear by?

You are absolutely correct - I have never done this exercise. 

Any tools, APIs, or approaches you’d recommend?

The Tampa Bay area can really be the best of both worlds in terms of appreciation and cash flow, as long as you execute correctly.

You are correct re the POA.
