I am looking into my STR options but from what I have learned this is a overflowing market in the area and the vacancy's are increasing so I may look into mid term and long term only.

Many good rental options in San Antonio/New Braunfels area.

If you're open to expanding your options, you may want to check the Columbus OH market. 

Unfortunately, such a funding option is not generally available for commercial properties, unless your LLC or Corp that is the borrower has other "unencumbered" assets that can be leveraged to generate the funds you need. 

I’m going to talk to them today about the complaints that I am getting, but if this pursues, what exactly are my options in this situation? 

If you ever want to explore other funding options for future flips, let me know! 

@Nicole ShoafYou are correct and have equity locked up in those units, a good lender can give you options on HELOCs or other loan products that could help get some equity out without selling.

I recognize that commercial real estate is struggling, with ~30% vacancy in downtown Portland and homelessness issues, but I believe this property’s tenant stability and quality make it a lower-risk option. 

I believe it to be a little Southern California hidden treasure for cashflow, mainly class C but if you know what you are doing its a really good option to invest locally in CA with decent returns.

I recommend that you find a trusted or recommended Mortgage Loan Originator (MLO), who can give you options for property-based loans (mostly investment loans) and they don't use your taxes but the P&L of the property.
