California is my 2nd biggest market, I hate the franchise tax lol behind Texas I have never done a flip and made less than 70k..what you have to keep in mind is that all markets are the same.

So my biggest question is, what are the main things I have to remember when doing wholesale here in Hawaii??

Maybe look at FHA 203k...google it..At the end of the day if the numbers make sense in your area then it's pretty cut and dry...Also if your circumstances allow you may want to actually reside in the in-law and rent out the rooms individually in the house which will almost certainly generate more revenue. 

One of the biggest advantages to becoming an agent/investor is the great networking opportunities that you can get from your team both locally and nationally.

One thing that I would recommend, particularly when you start out, is having multiple revenue streams.

Most brokerages today are not insanely different, but what makes the biggest difference is the people there.

The biggest things to understand: Buying right, getting the rehab amount correct, having a rehab contingency, completing the rehab on time, getting the ARV right, and being able to refinance out into good debt. 

As a Broker the biggest problem we encounter is a license performing licensed activities outside of the brokerage.   

One of the biggest mistakes is going outside of your criteria when it's taking longer than expected to get something under contract that fits your criteria.

Networking has been my biggest help in my real estate career.
