Try to put a bigger down payment in than you might need to give yourself some breathing room.2.

I’m doing DD and figuring ways to mitigate risk.

Put a little more money into that one and keep it for a while.

I could have put less down on the primaries but I put down 20% to avoid PMI.

When more buyers come to the market and put in more offers it drives up bids/offers.

Obviously geographically the risk of a major earthquake is real with the New Madrid fault being close by.

- If you are putting an offer in on a property to get that property under contract, part of the contract is that you put up earnest money.

In fact, it is usually an automatic no deal unless you are putting 50-60% down for an investment property, but at that point, it wouldn't be worth putting that much cash down on an investment property where you can get much better returns in markets such as Denver. 

Offer a personal guarantee (reduces investor risk if you have the balance sheet for a PG to be worth anything).  

Quote from @Scott Bloom: You can get a commercial grade policy from major carriers where they lump the risk across multiple properties into one policy, reducing your premiums.
