Best way to use $100K on additional properties

[Anthony Arredondo]

Hey guys, someone told me to check out Bigger Pockets when I asked this question elsewhere, so I'll give it a whirl by seeing if anyone here has any opinions about this.  I'm a full time landlord now with three properties, and I've managed to accumulate $100K through short term rentals, long term tenants, and a bit of cryptocurrency on the side.  It's not hard to find a duplex here for $80K.  Does anyone have any thoughts on the best use of this money to step up my real estate game and buy more properties?

I figure buying a house with cash would give me some negotiating power and maybe I could talk them down $5 or $10K.  Then I could cash out refi and buy another.

Alternatively, I could just use it for three downpayments and get three more houses.

Alternatively, I could just hold onto it and see if the market takes a hit in the next year or so, then be glad I waited for the right time to buy.  

Anyone have any thoughts?
