If you're goal is to keep it, you could take a short term personal loan or cash advance with your credit card.

The bid price is $281,000, and I have $180,000 in cash.

Very good cash flow and it has definitely appreciated over the year I had it.  

Focusing on multifamily properties for better income and cash flow potential makes sense, given the current market conditions. 

Purchase price: $1,280,000 Cash invested: $400,000 we were presented with the deal by a flipper needing to exit the deal. it was only rentable for $4500/mo as is, so we created a second unit. now it brings in $7200/mo What made you interested in investing in this type of deal?

I keep coming up with negative cash flow on many of the investments I am interested in.

There are lots of BRRRRs that hit the 1% rule and with positive cash flow!

Typically, 15- 20% NET income based on cash purchases.All the best  

My wife and I live in a duplex I paid $45,000 cash for back in January 2017.

The homes were not in Richardson, one in Paris TX and the other one in Kentucky.I bought them with cash and financed them both, to owner occupants, for $2,000 down and financed the rest.
