Shorter term CD's actually have higher rates than longer term so staying in the 3-6 month range is best.  

Because of where interest rates are at—and how slow everything is moving—we basically made a "take it or leave it" deal.

What is the current interest rate on a private money loan approximately $300Kthanks 

If you've owned for at least that, you're good.If you do a rate/term refinance, where just the hard money balance is paid off, rates will be much better.

I will say that during that time, the HELOC interest rates were very low.  

Hey @Brett Baker, generally, any place with a great water view or directly on the water will bring more revenue.Of course profitability will all be based on purchase price and prevailing nightly rates in the area.If you find a cool 2/2 or 3/2 right on the water with a great view for 1.5m or a 2/2 or 3/2 house a block away for 600k, then I would look at the house over the condo.

Our primary property management partner oversees more than 200 of our clients' properties and offers MTR management at competitive rates (I do not receive any referrals btw).

There are other options, the $60,350 mortgage does exist, but you didn't say what the value of the property is, but the variable rate mortgage of 8.75% to 11.75% indicates several thing. 

I just got something small and well within my means - refinanced when rates got low and now it's a decent little cash flowing rental 

While a western WA deal might not meet some Midwest cf metric like 1%, it will be above the market cap rate or below FMV of comparibles and give you options.
