Would the investor have to use an assignment contract between him and new end buyer to collect the mark-up fee aka assignment fee at closing?

When it comes to getting loans, which is pretty important for real estate investors, simple "mistakes" can make it so that you either don't qualify or you may qualify but with a higher interest rate or higher loan fees. 

I have a non-residential commercial mastermind and the fee started at $2500 in season 1. 

@Edreco AmosMiami’s market can be tricky for cash flow since condo fees and insurance costs can eat into your profits, especially with newer buildings or those near the water.

Quote from @Patrick M Nichols: Cogo is a total scam... lots of fees on the front end.

You let it slide, waive the late fee, and she pays by the 10th.

They will take the permit fee and send an inspector that will provide some assurance that the work was performed correctly.

That is part of the problem with a lot of companies (I am not knocking insula as dont have all the info/facts just stating how the business works), they engage brokers to get them loans and the brokers collect a small fee. unfortunately many of the brokers may be similar to real estate wholesalers - have little to no experience. 

I have already spent quite a bit on attorney's fees myself. 

This is my first time buying a home and let’s just say I learned a lot about these fees.
