You will have annual fees- NAR, MLS, etc regardless if you sell a property in those 2-3 months or not.

If you're plan is only to help others once in a while, you'll quickly start to realize that between membership dues (NAR, MLS and local Real Estate membership dues) not to mention monthly office desk fees (regardless of whether or not you work from home) and yearly fees associated with yearly 6 hours of required Continuing Education courses will keep you in the red and start to bleed you dry if you don't have enough business to cover these recurring costs.  

In some locations you must not only be licensed, but also a Realtor (member of NAR). 

I use the standard NAR Hawaii lease which has no mention of pests, which I will definitely amend it moving forward.

You can not have access to MLS unless you are a board member and NAR member which you have to pay a fee and have access to a key. 

I honestly think the Seller was surprised the Buyer did an inspection.Also, there are also Natl Assn of Realtor ethical standards to worry about for anyone who is an NAR member.

Violates NAR code of ethics?

However if the listing agent has not disclosed a variable rate commission, and then subsequently engages in one, that is against the NAR's MLS policy, and though I cant speak to every state, is likely illegal, as it is in the states Im licensed. 

NAR has long known that it was proprietary access to sales prices that gave Realtors an edge in pricing and selling homes, so they want to restrict the data where they can.Most MLS data across the country has now been aggregated (sold) into many databases and major lenders have access.  

A bit NAR-focused and the interviewer needs to come up with new adjectives, but worth the listen overall.
