for double closing you would need your funds to buy then sell it to end buyer at premium. there are transactional funding companies that can lend the cash for a fee.

I would recommend you look for a good neighborhood to buy a multi family in.

Would you recommend their realtor team for the buying process or should I look elsewhere? 

However, can you buy real estate without using any of your own money?

@Eric L Conry you are essentially borrowing on your property to buy stocks.

or any experience buying homes at auction in Sac? 

I try to help people with their issues even if that means I dont buy the house.

Also, I've always wondered why arbitragers don't negotiate an option to buy upfront?

In some cases, federal tax credits like those for low-income housing or economic development might also apply if the project aligns with certain goals.Instead of buying the land outright, developers often lease it from the tribe, which can reduce upfront costs and sometimes come with favorable lease terms.
