I was wondering what would be my better option to get a down payment for my next property.

I know it is too late at this point but should you find yourself in this position in the future I would utilize the 1031 exchange option.

There are lots of lookey loos on this platform that never actually do a deal.

Dividing it up into 17 acre lots would be an option as well.

If you plan to use a third option, look there as well. 

Mom and pop NY brokerages would be a better option, but they will have no training or systems, but will hold your license while you look.

Since you're selling 8 SFRs, this could break up into multiple distinct exchanges (most likely), but you have the option of combining multiple sales into single exchange purchases. 

The self serve option is hit or miss, I wouldn't use it in a city with strong squatters rights.

Do I have any other options?

We've also discussed the fact that these are all optional, cosmetic things that if don't fit in the budget, simply won't be done or will be done at a later date on my own when I get around to it.
