The biggest reason I would consider doing it is quality control.

Regarding paying off the SBA-HEDCO loan, the primary downside to paying it off early would be losing out on a relatively low interest rate.

The down side is this will cost you a higher rate, but the property will be in your LLC.

I have found an off market multi family property I think I could get a good deal but I noticed the quit claim deed when doing research and was wondering what the down sides could be? 

Naturally my biggest hurdle is the capital to fund the projects.

I would tell you the biggest thing is finding which market is a good rental/appreciation area.

The biggest (that people talk about) is 'due on sale'.  

The downside of this may be high turnover rates.The real estate agents and property managers operating in this zip code, may have more to say on this. 

The biggest key to you doing a refinance will be to target your monthly savings. 

.- my biggest complain to 401k is actually not the employer matching, but lack of diversfication where I can receive high cash flow with low beta structured portfolio.- for example, although SPY lost 28% their value in 202, but as total return, my portfolio is flat because my dividend income is offsetting the market gain losses.- what I am trying to say is that, if you are a "professional fund manager", you could create your set of portfolio that could beat the market , in this situation , the 401k is even less important.
