With the recent appreciation, it made sense to refi back to a highly leveraged position and redeploy that capital to where it can produce higher return than it was achieving trapped in a property which was reducing the leverage.  

The good news is that there is an unusual split in the market now, which won’t last forever, of which you can take advantage.Residential properties, at least in SoCal where you own, are still selling for relatively high prices.

Street lights, pot hole maintenance, water quality, sewers and hospitals... are vital to safety and the value of your real estate.

Your input will be highly appreciated.

High liquid cash is fairly low as I am just finishing up a rehab.

There are high yield funds and securities doing over 8% you can use if you want.Also, you could take the funds and do private lending at around 12%. 

The seller falling off the radar has a high likelihood, I never thought of that.

Consider taking advantage of high interest rates by buying first trust deeds, currently paying 9.5% and outperforming most new rental purchases.

Also @Ashish Acharya and @Michael Plaks are very active in the forums and highly recommended.

It's in Rosharon, Texas and property taxes seem high at 3.19%3.
