I guess it's just too many factors to consider and it easy to get overwhelmed and cannot get accurate info and estimation when I conduct analysis (ex. property tax rate, insurance, maintenance fee, rent, repair, closing cost, etc.) 

They will investigate and see if any rules were violated.

It hasn’t been easy, that’s for sure.

Fees should be clearly stated in writing, easy to understand, and justifiable.

My accountant was charging $100 each which I thought was a little high they are very simple if you have an easy platform .

The rule of 5's, or 5% for capex, maintenance and vacancies is going to get you in trouble.

From my experience: SMS has the best conversion but is the most regulated, so it depends on the rules in your market. 

Quote from @Brandon Foster: Hello Ryan,STR is do able in the north county area but there are a lot of rules and regulations.The city of Oceanside right now will not allow anything STR unless it’s west of pacific coast hwy.This is changing a lot too so you need to be aware of that in your plans.Carlsbad is super strict too but there are some condos that are still available to do STR in.Medium term rentals are as safer bet but way less profitable.

Yup, this is exactly the reason that I wouldnt allow delegated correspondent - it's too easy to get greedy and gloss over red flags when you get paid to package and sell risk to your partners instead of bearing it yourself.

Zillow has an easy application for them to fill out. it come back with a credit score and background info.
