So I’m renovating the one side and going to rent out the boat slips where I can put 5 boats tied stern too, but he shows me on his lease where the seller and realtor signed a revised lease that he has use of the dock for his boat. 

We’ve been developing at both ends of the spectrum (high paid tech and middle class manufacturing/service industry).

The cost for signing up for classes is about $300.00, and I've heard from other sources that the exam itself costs around $125, with a few administrative fees once you pass. 

Also, a side note, the education their child has received has been sub-par due to at home and hybrid classes.

I'm in a similar boat, but i have out of state properties that cash flow (less than 2 years) - my lender has told me the majority of the cash flow will essentially count as income for me. 

I am currently taking property management classes at the same time looking to get into a landlord training class either way i'm jumping into my first multifamily with in the next 25-30 (when my cash out refi closes) In the meantime I have been learning as much as i can in the landlord/property management areas while still searching and analyzing deals.I am investing in Massachusetts  and not apposed to investing out of state.

If their buyers agent has done only a few deals it's really no different than working with someone unrepresented anyway because at least in PA the licensing classes teach you nothing about actual real estate practice.  

Instead of asking if you should get it, you should research what being a real estate agent entails and if it will benefit you.if you have another job, you will likely be doing the real estate license part-time.There are two main reasons that people get the real estate license1) To make money via commissions2) to have access to the MLS and view properties(I don't think this is a good reason as you can view sites like zillow/trulia/redfin)Real Estate investing is hard in itself, no need to spend the many hours taking classes/exams to complicate the investing portion of real estate.

You need to really drill down to the market, neighborhood, property type, property class/condition, etc. 

The property is in a B-class neighborhood, built in 1920s. 2 of the 4 units are rented.
