Funds can come from a gift from family or from a business partner who is a co-borrower on the loan. 

With that said, for my friends first flip he contacted a co-worker and was able to access money from the friends IRA. 

I tried to sell this townhome when I first moved up north, and used a co-worker at the hospital I was working at who was completely horrible, was a realtor as a side hustle and had no idea about the market temp, and listed my townhome waaaay above where it should have been which resulted in it sitting on the market forever.

Have a duplex in RR coming up for $375k being listed by a co-worker

Two bedrooms is great, alas, we're already adding a 5th bedroom into the second living room and running a co-living model.With the carport conversion,it would be 7 bed, 3 bath.

Another route that I’ve explored is getting a commercial loan, which in theory would not require a co-signer, because the bank looks less at your personal income, and more at your ability to pay the down payment and the property’s ability to cash flow.

@Joe SplitrockSo she was given a chance by current landlord to purchase property but she couldn’t get approved by lender even while having a co signer.

However, I am a Co-GP on this deal, not the sponsor. 

I am new to real estate investing and own a co-op in Brooklyn, New York.

As a newbie who wants to get their hands dirty and add value, what tasks can an inexperienced person do as a co-sponsor or GP in their first few deals with a larger company?
