I prefer to use in- house platform messaging for basic messages, and actually write personal messages for anything else.

You either have personal knowledge or boots on the ground so you won't be throwing a dart at a place you know nothing about outside of a spreadsheet.

They are expensive $200 each but they do not break down and you can track who uses codes so a family could each have their own code per person.

The sharks at the meetups will be obvious avoid them and build relationship with everyone else.

Once you have those personal experiences from managing your own property, you will be able to identify and vet these property management companies when they're trying to make excuses of whatever the reason is as it stops you from achieving your objective. 

When that person said that, we realized how much power we had to negotiate terms that helped us reach our goals.You can't just take what's being offered when you negotiate.

Build the relationship with them.

Just like you would do with any non-family contractor working for you:- get them to complete Form W9 for you, as you will need their SSNs- have them provide receipts for materials/supplies and keep those receipts- have a written labor agreement (how much and for what) - pay for materials separately from labor- make all payments electronically rather than cash so you can trace them- pay out of your business account, not personal- issue them 1099s next year if you paid them $600 or more for labor (for the whole year, not per job): https://www.biggerpockets.com/forums/51/topics/1167632-expla... 

I am currently reviewing the numbers associated with a wraparound mortgage and I need some assistance in determining if they make sense.Can anyone please direct me to the appropriate person who would be able to help me analyze and verify these figures?

A very good local agent would be the starting point of the conversation for me personally.
