they charge a fee to the sponsor to list their projects and provide them the platform with access to their registered investors?

I think the bank will start to charge additional fee when the number of accounts exceed certain level.   

My title company charges me $5.00 for that.

So if a house costs $565,000 and escrow charges 0.8%, escrow costs $4,520, right?

He may come out and give you a quote for no charge. 

That will cause almost anything to fail and wear out far faster than normal, probably void any warranties, plus will likely create a trip hazard at doorways and perhaps unsteady walking conditions across the expanse of the flooring, which would be a hazard to health and safety in itself and expose you to liability if someone were to get hurt as a result. 

The faster you can make that happen, the better.  

Consider coming out to our REA this Monday night (free of charge). 

My other question, seems like most banks charge fees for accounts with less than certain amounts.

If you have a good amount of cash reserves, you will find an partner / investor faster.
