Is that monthly expense worth the guaranteed of having access to that amount for future investments?

There is no guarantee you will have access to those funds later so secure them now and be ready. 

When you talk about "finder's fees" I don't know if you're talking deal assignment fees (which we do pay and are normally 5% to 10% of face value of deal) but if you're talking about a "buyer's broker" I would not touch that as it will end your access to "pocket listings" which are the best of the broker's listings (and not publicly available). 

Turns out the flashing along the siding of the house was shot.I run Connecticut Property Management, and make our contractors list completely accessible to the public. 

Hello,I currently own a rental property in Littleton CO and at a point, I need to sell it in 2020 to access my equity to purchase more rental properties.

My Bank has approved a loan for the balance but I won’t have access to the money for another 10 days.

If you have MLS access, you can download sales data by neighborhood (at least in my market).

I feel I could be a great real estate agent and it would be a good way to make money until I started investing but if I could find a way into real estate before I’m 18 ( unlikely but not impossible ) then I think it would be more of a hinderance and something I’d have to schedule around, but then again 2 years of struggle could give me access to mls listings for the rest of my life.

If you don't have access to comps, get your realtor to put some comps together. 

What sold me was the calculators + the treasure trove of back material + potential for mastermind access.
