The only way I can access is money is through my primary residence and doing a HELOC.

For the second property, I would expect to have to put money into it in some fashion.

We were paying a bookkeeper $450/month, plus the $90 QB subscription to do our books but I felt like we were still having to tell her how to categorize everything so it just didn't feel like we were getting our money's worth.

hard money How did you add value to the deal?

Move the money in and out as tenants move in and out.You need two accounts: checking and savings.

The days of cash flowing and not leaving any money in the deal is gone(unless it's a unicorn). 

If not and you wrote them the check, then most likely the $ is gone and suing for that money will cost you more than $1000 unfortunately.So cancel the agreement and request the funds

Yes, they are actually selling individual units as well

If the cash-out refinance option isn’t providing enough liquidity, you could also consider a hard money loan, though these tend to come with higher interest rates and shorter terms.
