By no means am I an expert but I tend to be very organized and our systems have worked well for us.  

Even when wholesalers “kinda’ admit to the seller that they are going to “wholesale” the property, they still tend to mislead the seller by talking about “financing partners”, “equity positions”, “mentors” “membership” etc.So, various states have, under the banner of consumer protection, enacted legislation to restrict the use of the “wholesale” transaction in RESIDENTIAL OWNER OCCUPIED real estate - note, not commercial property and not residential when the transaction is between 2 investors. 

Also, most deals tend to require a lot of capital ($50K+).Most states exempt business purpose loans from licensing requirements but there are still certain rules/regulations you have to be mindful of.

There are a lot of HOAs there, but they tend to be STR-friendly.

Campers tend to be more leisurely in nature than tenants too. :)   

Furniture tends to rapidly depreciate while real estate tends to appreciate.

I don’t tend to do much plumbing drawings, especially when it get complex or extensive. 

Insurance placement guests tend to be very last minute, often will want to sign an initial 30-day contract and then the amount of time they will extend is very unpredictable but can sometimes be upwards of 9 months.

Cosigners tend to be helicopter parents that meddle too much and then refuse to pay when little Johnny runs up the bill.

Same goes for number of LLCs and what to fund them with, since bear in mind that CA tends to be more cumbersome and expensive to have LLCs than other states.California is generally more cumbersome than other states when it comes to taxes and filings.
