The fact that you  already had two closings in your 1st four months is amazing.

Called a few Foremost agents in NYC and either no pickup or don't do over 3 units. :( :( 

The real estate agent doesn’t pay for problems.

Also you should inquire with insurance agents about the cost to insure.

When my loan was not going to close, it was one of the options that my broker and lender told me about and actually referred me to for a conversation.

If you’re In a title state make proof of utility pay off a condition of closing.

@Jason Weidmann what do you think of every agent responding telling you to go, go, go!

I have found that they worked really well when it comes to getting better tenants and better rents, and having less hassle, less headaches, and then getting a higher sales price; without paying closing costs or realtor fees.

Quote from @Shawn Questa: A few times I've reached out to Cash Buyers and they would tell me that they are a part of an Investment Group and that they are ready to quickly Close Deals would be happy to work with me.Later I would come to find out that they are actually a Group of Wholesalers, like me.I guess I would prefer to Work directly with the Investor, Cash Buyer or Flipper. 

I own a few and so do agents on our team.
